Refrigerant recovery machines for HVAC are used to remove liquid refrigerant from an HVAC system and then transfer it into a storage cylinder. This allows the service tech to reuse the refrigerant in a different piece of equipment without paying for new refrigerant or dumping it back into the atmosphere. These machines are typically used on large commercial HVAC jobs but can be used to recover small amounts of refrigerant for residential use.
There are a number of factors to consider when choosing the best refrigerant recovery machine for your needs. You will want to consider the size, power, and speed of the machine. You will also want to consider the after-sale support offered by the manufacturer. A good warranty will protect your investment.
Another consideration is the type of compressor used by the machine. There are 2 types of compressors used in these machines; oil-less and hermetic. The type of compressor that is used in the recovery machine will affect its performance. Oil-less machines are usually the faster option but tend to cost more than hermetic models.
Lastly, the hoses used by the recovery machine can impact its performance. You will want to choose large hoses that will not restrict the flow of refrigerant. You will also want to make sure that the hoses are properly set up. The little rubber grommet that seals the end of a flare fitting can sometimes become deformed and severely restrict the flow of refrigerant. Refrigerant recovery machines for HVAC
