If hooking a can of refrigerant with a single hose/gauge to the car, you will use the low side. 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. 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. Our industrial cleaning services team provide critical services for daily maintenance, turnarounds and outages for the oil and gas, refinery, petrochemical industries. 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. 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. Open All Close All. It then travels through injection piping into the process unit (hydrotreater, sulphur recovery unit, etc.) Learn more about the nitrogen vs. air debate to make the best decision for your vehicle. 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. This cool gas mixture is used in the same manner as the gaseous cool down to accelerate the cooling of the reactor system. I wheeled over the nitrogen bottle, connected it, pressurized the system, and immediately heard hissing from low in the engine compartment. 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. 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. 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. Nitrogen gas of a specific minimum miscible pressure is used for the operation. 24-Hour Support – Call 780-868-9622 We offer nitrogen in multiple purities and supply modes. 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. Local Supply in Fort McMurray Our large fleet of nitrogen pumpers, bulkers and tube trailers are ready to meet any demand you may have. The leak gets identified, thus. 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. The lack of reactivity of nitrogen is its biggest quality and as a result the gas is used to prevent slow and fast oxidation. It has several properties that make it an ideal tool for use in the energy industry. Then you watch the gauges and listen. It is also non-flammable: a nitrogen atmosphere will not support combustion. Under the hood is a 15 horsepower air motor originally designed to power a winch for raising ship anchors. 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 … 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 In the book, I describe using nitrogen to pressure-test an empty air conditioning system in order to find leaks. This liquid is then stored in a vacuum, and heated back into gas at a later time. I re-pressurized the system, and it held. 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… I consulted a dedicated air conditioning specialist, who pressure-checked my car’s system with nitrogen gas, which does not damage the environment. SÜA - Nitrogen Gas Regulator 0-600 PSIG - HVAC Purging - Pressure Charge - 1/4" Flare Connector. 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). Sitting at the heart of these systems is a device about the size of a large coffee can, called a compressor. 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.
