Refrigerants generally will have high molecular weight compared to oxygen. When refrigerant is leaked from the system it may replaces oxygen in closed rooms. Therefore there may be situation arise due to lack of oxygen leading to headaches, unconsciousness and even death.

Faster recovery is with warm system and cooler recovery tank. Warmer the system, warmer and denser the vapour will be and faster the recovery time.

Recovered refrigerant shall not be sold without Reclaimed. Reclaimed refrigerant shall meet ARI 700 purity standard.

Refrigerant can be recycled by separating the oil from the refrigerant and also removing moisture by passing through one or more filter dryers. This recycled refrigerant shall be used in system which it is recovered. Recycled refrigerant shall not be sold to new owner.

When chlorinated refrigerant hot vapour is drawn on the heated copper element (heated using hydrocarbon fuel flame), it forms copper chloride which changes flame color from pale blue to bright green

High pressure vapour enters the condenser and flows through the tubes where it rejects the heat. As the heat is removed, refrigerant reaches saturated temperature and changes phase to high pressure liquid

Not just CFCs & HCFCs, all refrigerants shall be recovered before servicing

R-500 – CFC
R-22 – HCFC
R-123 – HCFC
R-134a – HFC

Ozone at lower level of atmosphere (Troposphere) is bad and pollutant. It is created in Troposphere by chemical reaction between oxides of nitrogen and volatile organic compounds. This happens when pollutants from cars, industrial plants, boilers, refineries and other sources reacts chemically in presence of sun light.

Class I refrigerant – Ozone Depletion Potential greater than 0.2 (ex: CFC)
Class II refrigerant – Ozone Depletion Potential less than 0.2 (ex: HCFC)
