What does acid scavenger do?
Description: The Rx-Acid Scavenger family of products provides a convenient way to neutralize or “scavenge” acid in refrigeration, air conditioning systems after burnouts or during normal on-going system maintenance. Normal dosage treatment of any Rx-Acid Scavenger product will address up to one gallon of system oil.
How do you flush a refrigeration system?

- Do a nitrogen pre-flush. …
- Prepare the lines. …

What to do after burning out a compressor?
A severe burnout will take much more involved methods of clean up. After replacing the compressor an oversized HH core filter drier and an HH core suction filter should be installed. After proper evacuation (triple evacuation) and recharging the system should be placed back in operation.
How do you remove acid from air conditioner?
The ideal method of removing acid is to liberate (or free) the acid from the refrigerant oil and hard surfaces, allowing the filter-drier in the system to remove it. A filter-drier does an excellent job of removing acid.
What is nitrogen flushing in AC?
It is the responsibility of the air conditioning engineer and AC technician to conduct flushing of the system using dry nitrogen to assure that all soot, contaminants and sludge are removed from the system.
Why is nitrogen used in HVAC?
Nitrogen is used in air conditioning to purge oxygen out of the copper tube to prevent the formation of scales on the inner surface of the copper tube due to oxidation that can cause damage to the air conditioner during operation.
Can we use nitrogen as refrigerant?
NITROGEN is used as a refrigerant. Nitrogen is a liquid at temperatures below −196. 50C and is used as a refrigerant for such things as preservation of blood and cooling of large computer systems, as well as some industrial uses. Being a liquid, it is more convenient to use for low-temperature cooling than dry ice.
What causes compressor to ground out?
Compressor burnout is a very specific mode of failure that may be caused by high temperatures in the motor windings or discharge area of the compressor. High temperatures break down the motor winding insulation, which may cause a loss of electrical resistance and result in a short to the ground or even an open winding.
What causes air compressor to seize?
Oil circulates with the refrigerant, so if the orifice tube or expansion valve is blocked it may cause the compressor to run dry and seize. Even if a compressor is still turning, it may have to be replaced if it’s leaking, making excessive noise or not working correctly.

What causes compressor burnouts?
Some common causes of compressor overheating are lack of external cooling, poor ventilation, short cycling, low suction pressure, high head pressure, lack of lubrication, excessive wear and tear, and electrical problems.
What causes acid in HVAC?
What Causes Acidic Refrigerant. When the refrigerant circuit is subjected to moisture, excessive heat, contaminants, or other impurities, it leads to a chemical reaction that creates acid. This condition is brought about by age (ordinary wear and tear), a lack of maintenance, or an improper system repair.
What is an AC acid Test?
Acid-Test, a universal acid-detecting diagnostic tool created by Cool Air Products, is a highly-portable and incredibly accurate test that all HVAC professionals should have in their toolkits. Compatible with all lubricants, Acid-Test allows for the quick and precise detection of acid in AC/R systems.
What can be used to reduce the acidity of a refrigerant oil?
An alcohol, specifically ethanol, methanol and isopropanol, is used to remove acid from a refrigeration system, a heat pump or an air conditioner. The alcohol vaporizes acid, primarily inorganic acid, in the system and, in the filter/dryer, reacts with surfaces or is adsorbed.
How do I purge my AC with nitrogen?
Purge the Nitrogen through the liquid line toward the compressor and discharged out the compressor discharge line before the compressor is connected. Disconnect the nitrogen after pushing off all contaminants on this point. Connect the nitrogen to the expansion device side of the liquid line.
Why Liquid nitrogen is not used in AC?
The reason Nitrogen isn’t used as a refrigerant is because it wouldn’t be very efficient. (Also, as an aside, refrigerant systems are vapor-compression systems, there is a liquid and a gas component to the system, not just liquid. Meaning, the refrigerant changes phase a couple times throughout the whole process.)
How do you test for AC leak with nitrogen?
Nitrogen Test
In this test, an AC/R professional will remove all refrigerant from the unit, replace the gas with compressed nitrogen, and listen for any sounds. Because nitrogen is held under greater pressure than the coolant, leaks create an audible hissing or whooshing sound as it exits the system.
What happens if a compressor runs with nitrogen?
Yes, it will overheat the compressor, as it requires the refrigerant vapor to cool it. Of course the pressures will be different, its still compressing the gas. If they’re not different, it’s not pumping. Of course it shouldn’t be run like this.
