Use dry nitrogen to push some of the contaminants out of the system by simply attaching the nitrogen regulator to one of the lines and allowing it to blow out the other. This attitude is universal at FourQuest, starting with our President through to the newest member of our team. The emptied air-conditioning system is filled with nitrogen (maximum 12 bar). Traditional nitrogen engine designs work by heating the liquid nitrogen in a heat exchanger, extracting heat from the ambient air and using the resulting pressurized gas to operate a piston or rotary motor. I undid the fitting to examine the o-ring under it and was astonished to find that the o-ring was missing. Liquid nitrogen is used as a refrigerant, which is able to rapidly freeze foods and subjects in medical research, as well as reproductive technology. Further, nitrogen gas is inert and has the capability to absorb moisture to a certain extent. Designed for detecting and locating leaks in automotive air conditioning systems using pressurised Nitrogen gas. While sniffers are highly effective in finding small leaks in charged systems, there are problems with the first two methods. This cool gas mixture is used in the same manner as the gaseous cool down to accelerate the cooling of the reactor system. Local Supply in Fort McMurray When you need to pressure test an air conditioner’s condenser unit with nitrogen gas you might think there is no danger associated with this. LEAK DETECTION USING A NITROGEN SET In addition to its function for drying the system, this tool can also be used for leak tests. The wonderful utility of pressurization was displayed in a repair I just did. Depending on the system design, nitrogen can be used for accelerated cool downs in either a gaseous or liquid phase ranging from -196˚C to +400˚C. The best-case situation of the leak being caused by a bad o-ring—quickly found and easily replaced—is about as likely as a loose gas cap being the cause of your check engine light. The Nitrogen Advantage. Everything we do in the field, we engineer first. We offer compressed and liquid nitrogen in various grades specific to different applications, such as: • A coolant for concrete work • An assist gas for laser cutting • A pressurizing agent in pipelines • A cryogenic for preserving biological material • A welding gas in automotive manufacturing Download spec and safe… Nitrogen is inert, nonreactive, nontoxic, and noncorrosive. SÜA - Nitrogen Gas Regulator 0-600 PSIG - HVAC Purging - Pressure Charge - 1/4" Flare Connector. After all, every breath we take is mostly nitrogen gas. In the book, I describe using nitrogen to pressure-test an empty air conditioning system in order to find leaks. Fuel efficiency dropped by a whopping 20 percent when the windows were open, but only by 10 percent when the air conditioner was on. Refineries, petrochemical plants, and marine tankers use nitrogen to purge equipment, tanks, and pipelines of dangerous vapors and gases (for example, after completing a pipeline transfer operation or ending a production run) and to maintain an inert and protective atmosphere in tanks storing flammable liquids. Regarding dye, I know that people swear by it, and certainly there’s no reason not to use refrigerant oil with dye in it when you’re servicing an A/C system, but I’ve never found it to be the panacea that other folks do. The inert environment created from nitrogen prevents any combustible reactions from occurring. You close the valves on the manifold gauge set, connect the red and blue hoses to the A/C service ports as you need to do for any A/C work, unscrew the regulator on the gas bottle all the way to zero pressure, open the gauge valves, slowly turn the regulator handle to introduce the gas until the manifold gauge set registers about 100 psi of pressure, and then close the manifold valves and shut off the gas valve. It … Virtually any reaction vessel operating at extremely high temperatures can benefit from the thermally engineered accelerated cool down service provided by FourQuest Energy. The time for all that, plus the recharge itself, is always going to make the bill more than $79.95. The liquid nitrogen can be pumped from the truck in its liquid form, or it may be converted to gaseous nitrogen, depending on the application. You can order personally inscribed copies here. Rob Siegel has been writing the column The Hack Mechanic™ for BMW CCA Roundel magazine for 34 years and is the author of five automotive books. The immediate sound of escaping gas from the front of the engine verified that a leak was very much apparent, which was … When produced in cryogenic facilities, nitrogen is shipped in liquid form and transported in specialized insulated tank trucks suitable for handling the extreme low temperatures of nitrogen in its liquid state. If the leak is smaller and the pressure drops over minutes or hours, you use an engineered soap solution such as “Big Blu” and look for bubbles. Ending the storage shell game and searching for car-centric property, Watch the Hyperion hydrogen hypercar hit the road, Chip Foose reimagines the iconic Jaguar E-type – Ep. Service both R114a and HFO1234yf gas vehicles with the Sun KoolKare Dual Gas car air conditioning machine – one unit covering two opportunities. It has several properties that make it an ideal tool for use in the energy industry. Potable Water Supply and Wastewater/Sewage Disposal. Although nitrogen-enriched gasoline may provide a slight bump in engine performance, some worry about adding to cars' already substantial air pollution load, especially nitrogen oxide In pressure-testing, you use a moisture-free inert gas to pressurize the A/C system. In pressure-testing, you use a moisture-free inert gas to pressurize the A/C system. The car has a Clardy A/C system in it, the rarest and coldest of the three dealer-installed options for this car when it was new. Our large fleet of nitrogen pumpers, bulkers and tube trailers are ready to meet any demand you may have. I carefully hunted around beneath the compressor on the engine mount and on the top of the subframe and found the smoking gun—a cut o-ring. Your first call nitrogen services provider. 2-Test is a nitrogen regulator/cylinder system, utilizing a lightweight aluminum cylinder and a “state of the art” regulator with an integrated cylinder valve. I tightened it up, re-pressurized the system, and watched the pressure gauges for a few minutes. It then travels through injection piping into the process unit (hydrotreater, sulphur recovery unit, etc.) Gas bottle gauges supplied with fitting for BOC nitrogen cylinders or disposable NitroTrace canisters – (NitroTrace contains enough gas for up to 12 […] Depending on the system design, nitrogen can be used for accelerated cool downs in either a gaseous or liquid phase ranging from -196˚C to +400˚C. These are cars with poor A/C reputations, which is precisely why I continue to use R12 in them. But the vacuum itself is really almost no help in finding the leak. During a once-through (gas-phased) cool down, nitrogen gas is pumped through a process system. Then you watch the gauges and listen. His new book, Resurrecting Bertha: Buying back our wedding car after 26 years in storage, is available on Amazon, as are his other books, like Ran When Parked. If a system needs to be recharged, it’s because the refrigerant has leaked out, so the leak first needs to be found, then needs to be fixed. 4.4 out of 5 stars 133. For the tiniest leaks, using a gas mix of CO2 and Argon is better than nitrogen, as you can then use a chemical sniffer to detect the argon. The nitrogen is vaporized by the warm gas stream and forms mixed gas at a lower temperature. But in 2012, Consumer Reports tested a Honda Accord and found mileage dropping by about 3 miles per gallon when the air conditioner was used and when the car was going 65 miles per hour. Nitrogen gas of a specific minimum miscible pressure is used for the operation. I wheeled over the nitrogen bottle, connected it, pressurized the system, and immediately heard hissing from low in the engine compartment. Nitrogen is an inert (non-flammable) gas – basically, nothing more than dry air with oxygen removed. I got into the habit of using nitrogen, because I had a tank of it left over from a dune buggy project decades ago that used nitrogen-filled shocks, but you can use CO 2 or other inert welding gases. Avoidable Contact #89: If BMW were a person, would this be a cry for help? The high-temperature vessels used in the energy industry for a wide range of processes and products can often take days or even weeks to cool down to manageable working temperatures. When pressurised nitrogen charged into refrigerant circuitry leaks through a soap solution applied on the circuitry, forms bubbles due to chemical reaction with soap solution. The most notable advantage of nitrogen-filled tires deals with tire pressure, which you already know is crucial for keeping your tires in good shape. I continue to use R12 in two of my cars—my 1972 BMW 2002tii and 1973 Bavaria. I felt with my hands and isolated it to the inlet (suction) hose fitting on the compressor itself. The different types of auto compressors vary in how they handle air exchanges between the car … It is therefore used to remove moisture from a refrigerant circuit which may have been subject to some repair involving exposure of inner walls of the circuitry … Additional nitrogen to complete the cool down is brought to site in specialized transport trucks. So, even if it’s a bad o-ring, it’ll never cost you the advertised $79.95 at a service station. If hooking a set of gauges to the vehicle, you will use both. We offer nitrogen in multiple purities and supply modes. Sign up for the latest automotive news and videos—in short, everything for people who love cars. This liquid is then stored in a vacuum, and heated back into gas at a later time. Mr. Zoran Bajic is the Director of Research and Development and one of the co-founders of FourQuest Energy. In fact, ambient air contains about 78% nitrogen, 21% oxygen and 1% miscellaneous gas. For leak tests, a filling adapter is required for the service connection as well as a tube adapter. With zero ozone depletion potential (ODP), our gases meet the world’s toughest environmental standards. A liquid nitrogen vehicle is powered by liquid nitrogen, which is stored in a tank. Top quality British made regulators with Swedish manufactured hose. *Most 1994 and older vehicles used R12 as the original refrigerant, if the vehicle being serviced is still using R12, it must be evacuated and retrofitted. If hooking a can of refrigerant with a single hose/gauge to the car, you will use the low side. 4, 1969 Oldsmobile Toronado: Swank ’60s style, 5 pieces of terrible advice I’ve been given about project cars, Smithology: If you’re a vampire, or maybe a rock, Wrenchin’ Wednesday: Stop hacking up factory harnesses. Put simply, shutdown time is significantly reduced so that maintenance work can start sooner in a safer environment and with lower overall shutdown expenses. Piston Slap: Bringing the notch to an STI’s shifter, 2020 Indy 500 will run with fan capacity limited to 50 percent. to be cooled. FourQuest Energy provides an integrated services platform to the energy industry to help our clients achieve safe plant startup, and efficient maintenance and shutdown servicing events through our detailed engineering and expert field execution. The leak gets identified, thus. Supplied with R134a and R1234yf low side couplers. I pressurized the system, let it sit overnight, saw in the morning that the pressure hadn’t changed more than could be attributed to temperature, evacuated it, charged it up, and was very quickly greeted by a cold car. Through our years of experience utilizing a range of chemical providers, we have determined the Company FQE® Chemicals to be the superior provider in the market. Regardless of whether you choose to use the AC or roll the windows down, there’s no method to cool your car that doesn’t lower your car’s fuel efficiency. Without compressor in the system, you can safely use 250 psig for high pressure refrigerant systems. You can and should pull a vacuum, look at the reading on the manifold gauge set, let it sit for some amount of time (overnight is best), and see if the vacuum reading drops, because if it does, there’s a leak somewhere. 24-Hour Support – Call 780-868-9622 The air we breathe every day is made up of 78 percent nitrogen, 21 percent oxygen, and one percent argon. A-ha! At very pressures (up to 15,000 psi), N 2 forms a miscible slug with a powerful vaporizing drive which improves the hydrocarbon recovery factor. I put a wrench on the fitting and found that it was very loose. Nitrogen is produced in large volumes in both gas and liquid form by cryogenic distillation; smaller volumes may be produced as a gas by pressure swing adsorption (PSA) or diffusion separation processes (permeation through specially designed membrane). And instead of generating plumes of foul exhaust, the LN2000 emits cold nitrogen gas which freezes water vapor in the air to form small clouds behind the vehicle. Leak testing using oxygen free nitrogen (OFN) Nitrogen has a molecular structure which makes it suitable to find most leaks, and in addition it is reasonably priced. Specifications ... Nitrogen leak check kit; Optional extras. Under the hood is a 15 horsepower air motor originally designed to power a winch for raising ship anchors. Our vision is a workplace free of incidents and injuries, and as a result, health and safety is integrated into every aspect of the work process. Proper engineering design optimizes the accelerated cool-down portion of the plant shutdown process, allowing our clients to better plan and execute shutdown activities beyond the time savings provided by the ACD. It is therefore important to compile as much information as possible regarding these parameters during the engineering assessment. With our wide range of integrated services, our clients can expect a safe plant start-up. A car that is too hot can lead to drowsy or distracted driving, which can … Sometimes leaks are small enough that the amount of visible dye is miniscule, and old dye left over from other work can confuse things. In my book Just Needs a Recharge: The Hack Mechanic™ Guide to Vintage Air Conditioning, I make the case that those “A/C recharge $79.95” signs you see at service stations are perilously close to fraud. Refrigerant Gas Our range of refrigerant gases can be used for transport, refrigeration and air conditioning applications. But admit it, you were just itching to buy those anyway. I re-pressurized the system, and it held. IMPORTANT: DO NOT exceed the recommended pressures (use a pressure regulator). But that’s still the most minimal A/C repair possible, and if you do it yourself, you can find the leak quickly through pressure-testing, and it shouldn’t cost more than the o-ring and the R134a refrigerant. I consulted a dedicated air conditioning specialist, who pressure-checked my car’s system with nitrogen gas, which does not damage the environment. He brought the car by the house, and I connected the manifold gauge set to the charging fittings on the back of the compressor. Flowing cold nitrogen through a unit can also substantially reduce the amount of time it would take to cool the unit than if it were allowed to cool naturally. Our industrial cleaning services team provide critical services for daily maintenance, turnarounds and outages for the oil and gas, refinery, petrochemical industries. Choose the method that makes you the most comfortable while driving. When they were reconnected, it’s likely that the o-ring had gotten pinched. Nitrogen gas is the opposite, providing nonreactive environments where needed. As the gas moves though the reactor, it exchanges heat with any matter it comes into contact with, resulting in an accelerated cool down. Save my name, email, and website in this browser for the next time I comment. I got into the habit of using nitrogen, because I had a tank of it left over from a dune buggy project decades ago that used nitrogen-filled shocks, but you can use CO2 or other inert welding gases. I’d resurrected the A/C in this car about five years back and was so impressed with how well it worked that I searched in vain for years until I found a Clardy system to install in one of my own 2002s. My friend had had the engine replaced in this car last spring, and it was almost certain that, as part of that work, the hoses had been disconnected from the compressor. Learn more about the nitrogen vs. air debate to make the best decision for your vehicle. The heat loss during a cool down can be determined using the following principle: ΔT = change in temperature (final-initial). Nitrogen (N2) is a colorless, odorless, and tasteless gas that makes up 78.09% (by volume) of the air we breathe. This calculation will define the overall heat transfer requirement from which the nitrogen consumption can be determined. 5, Chip Foose reinvents the 1966 Ford Bronco with street-savvy style – Ep. $38.99 $ 38. Nitrogen molecules are larger and slower moving than those of compressed air. They showed zero pressure, so all of the refrigerant had indeed leaked out, corroborating his observation of the white smoke. The nitrogen is transported to the site as a liquid via a nitrogen pump truck, equipped with a storage tank, diesel fired vaporizer, and cryogenic triplex pump. To be clear, using a vacuum pump to evacuate the system is a necessary step that you must perform prior to recharging in order to boil off and remove any moisture that might be inside. Holy moly. Another important application for nitrogen is to use it to cool and inert reactors filled with catalyst during the shutdown process for maintenance work. The next step would normally be to spray soap solution and look for bubbles, but because the suction fitting had been loose, I checked there first. Piston Slap: When the Signal Acquisition Module (SAM) surrenders? Cryogenic processes can produce very pure nitrogen. Nitrogen usually appears in either liquid or gas form (although it is possible to attain solid nitrogen as well). Nitrogen gas is used in the preparation of the catalysts and the transportation of polymer powders, It is used as a medium for the exhaust of emitted heat in the fluid bed reactors, and it is used to control the temperature in the reactors. DO NOT operate the air conditioning system with oxygen free nitrogen (OFN) in the refrigerant circuit. Open All Close All. Our technicians will check for further repairs and replacements to get your air conditioner in top condition. The lack of reactivity of nitrogen is its biggest quality and as a result the gas is used to prevent slow and fast oxidation. You need an adapter like this one available on Amazon to connect the yellow hose on the manifold gauge set to the gas bottle. Sitting at the heart of these systems is a device about the size of a large coffee can, called a compressor. Nitrogen is effective at flushing all contaminants out of the air conditioning unit’s system, enabling the unit to run without spreading contamination Nitrogen gas for air conditioning purging is readily available and relatively cheap to purchase 99 $55.00 $55.00. The liquid phase cool down, however, uses significantly less nitrogen due to the added cooling benefits of phase changing liquid to gas. I can tell you that R12 is some seriously great refrigerant; it gets both of these cars meat … The Dual Gas is a fully automatic and tapless unit. If a leak is large, the pressure readings on the gauges will drop immediately and you’ll hear the pressurized gas escaping. Nitrogen (N2) is a versatile gas used across a wide range of applications and industries, and we’re always ready to supply it for new applications that arise. ( Includes 6 months Warranty.) It is also non-flammable: a nitrogen atmosphere will not support combustion. Traditionally, car tires have been filled with compressed air. And the tools. If no leaks are found and your system passes all legal requirements, we can re-gas your car air conditioning system from $158.00. Do not exceed the system working pressure with nitrogen. It is designed specifically for the HVAC industry, for nitrogen purging AC line sets prior to brazing and leak checking AC line sets after brazing. Vehicles propelled by liquid nitrogen have been demonstrated, but are not used commercially. Most of what you read online says either: A) You find leaks with a vacuum pump during the evacuation phase; B) If you previously filled the system with oil with dye in it, and it worked for a while but now is leaking, you find leaks by using an ultra-violet light to look for the dye; or C) You find leaks by using a chemical sniffer on a system that still has refrigerant in it. His talent and interest in engineering and science have gained him two degrees: a Chemical Science degree from the University of Sarajevo (1985) and a Master’s in Engineering from the University of Alberta (1999). One such vehicle, Liquid Air … When using nitrogen in its liquid phase, cryogenic nitrogen fluid is pumped into a recirculating process of the unit gas stream with a specially designed nozzle. I’ve long been surprised that this is not a widely used technique. How liquid nitrogen could be used to power cars . When this happens, you can usually isolate where it’s coming from by simply turning the gas back on, opening the manifold gauge valves, and laying your hands all over the system components to feel the escaping air and localize it—or putting a piece of a garden hose to your ear and moving the other end around. Because of nitrogen’s inert properties, it is often used in highly specialized tire … Air conditioning (A/C) systems for cars can be an invaluable feature, especially in warm climate areas. I installed a new o-ring and for good measure removed the discharge fitting and replaced its o-ring (which was present) with a new one as well. Occasionally, however, you get lucky. It didn’t take long to see the pressure drop by about 1 psi per minute. A buddy of mine contacted me, saying that the A/C in his 1976 BMW 2002 was working fine until he saw a puff of white smoke from under the hood and the A/C quit working. Specific elements of the process unit, i.e., catalyst and metallurgy, each contribute to the total nitrogen requirement based on their individual masses and material properties. I then thought about it and realized that the odds that the system had been working for all these years with a missing o-ring were zero. During a once-through (gas-phased) cool down, nitrogen gas is pumped through a process system. Meet any demand you may have the warm gas stream and forms gas.
