Refrigerant recovery is the act of disposing of used refrigerant gas that has previously been used in some type of refrigeration circuit to bring it to the specifications of the new refrigerant gas.

What is the difference between recovered refrigerant and recovered refrigerant?

This is a used refrigerant that should go through a basic spot cleaning process, which is usually done by a contractor who does the job.Instead, the recovered refrigerant is Products reprocessed in licensed facilities Meets industry standard AHRI 700 to match original product.

What does « recovered refrigerant » mean?

Simply put, recovery means Transfer the system’s refrigerant to a refillable refrigerant cylinder. If the refrigerant is not burnt out by an enclosed motor or otherwise contaminated, it may be of sufficient quality to reinject it into the system after repairs are complete.

Why Recycle Refrigerant?

refrigerant is recovered to prevent them from leaking or dispersing into the atmosphere… If the refrigerant is vented to the atmosphere, it will have one of two effects: Chlorine contained in the CFC/HCFC refrigerant will travel upwards into the atmosphere, eventually causing damage to the O-zone layer.

What would happen if a recycling cylinder was filled with liquid refrigerant and allowed to heat up?

Do not overfill the cylinder. Liquid refrigerant expands as its temperature increases. If the cylinder is somehow completely filled with liquid, the pressure will increase dramatically with a relatively small increase in temperature.
