R134A AC Recovery Recycle Recharge Machine , Air Conditioning Charging Station

Why we need AC Recovery Machine?

When the air conditioning system on your vehicle is serviced, federal law requires the old refrigerant in the system to be recovered BEFORE any repairs are made that require opening up the A/C system. Refrigerant recovery prevents refrigerant from escaping into the atmosphere. R-12 can damage the ozone, and R-134a is a greenhouse gas that contributes to global warming.

Refrigerant recovery requires a refrigerant recovery machine that meets Society of Automotive Engineers (SAE) standards. If a repair shop does not have a refrigerant recovery machine (and a certified technician who knows how to use it), they cannot legally service your A/C system.

What is refrigerant recovery machine?

Refrigerant recovery machines remove refrigerant from equipment such as refrigerators , freezers , or air conditioners prior to repair or maintenance . They safely recycle and reclaim used hydrofluorocarbons (HFCs) from mobile and stationary HVAC units to help keep in compliance with EPA standards .

Refrigerant Recovery Procedure

Using a recovery/recycling machine is not difficult. The basic procedure goes as follows:

1. Connect the hoses on the recovery machine to the service fitting on the vehicle.
2. Turn the recovery unit on following the equipment manufacturer's operating instructions. Allow the machine to continue pulling refrigerant from the system until it indicates all of the refrigerant has been recovered (system pressure reads vacuum and holds vacuum for at least 5 minutes). If the machine does not have an automatic timer or shut-off, discontinue recovery at this time, and close and disconnect the service hoses.

TIP: If A/C components show evidence of icing during the recovery process, the components can be gently heated to speed up the flow of refrigerant. Use a hot air blow dryer, never any type of open flame, to heat parts.

3. Once the recovery process is complete, determine how much oil was pulled out along with the refrigerant so you can replace it when the system is recharged. Most machines have an oil cup that will show how much oil was taken out. The cup should usually have about one ounce of oil in it if the system contains the proper amount of oil. If the system is low on oil, there may be little or no oil in the cup. On the other hand, if the system is overcharged with oil, there may be several ounces of oil in the cup.

4. After the refrigerant has been recovered, the recycling process can begin. The time it takes to clean the refrigerant can vary from 20 minutes up to an hour depending on the amount of contamination. During the recycling phase, the refrigerant is filtered and dried. Particulates, moisture, oil and air are all removed until the refrigerant meets purity standards. A moisture indicator light usually signals when the job is done. The refrigerant can then be put back into the vehicle, or saved and reused in another vehicle.
Most machines use "single-pass" recycling where the refrigerant makes only one pass through the cleaning circuit, but some machines also offer "multi-pass" recycling or a choice of single-pass or multi-pass cleaning. Multi-pass cleaning takes longer but may be necessary with refrigerant that contains a lot of moisture.

The filter-drier that removes particulates and moisture from the refrigerant needs to be replaced periodically. Filter capacities vary somewhat from one machine to another, and lifespan depends on how much crud and moisture the filter picks up from the refrigerant. But as a rule, a typical filter will usually clean about 1,000 lbs. of refrigerant before it has to be replaced.
