Refrigerant recovery machines are one of the most important tools that contractors and technicians own. They help them get the job done efficiently and quickly, and they can also save them money in the long run by allowing them to recover refrigerants from old equipment that would otherwise be disposed of. However, many times these recovery machines break down or wear out and require new ones. Thankfully, there are plenty of options to choose from for HVAC professionals looking to buy new units.
The first thing that determines how fast a refrigerant recovery machine works is the compressor type. There are 2 types of compressors used in these devices; oil-less and hermetic. Oil-less models usually perform better than hermetic, but they are more expensive as well.
Another factor that affects the speed of a recovery machine is the liquid recovery rate. Liquid recovery takes less time than vapour recovery, so look for a model that has this feature. Also, make sure to use the shortest possible hoses when using a recovery machine. This helps to reduce hose pressure and increases efficiency.
It is also a good idea to check the recovery tank for air. This can be done by simply running a fan over the top of it, or with some models, water flow can even work to cool down the cylinder and speed up the process. It’s best to do this before starting a recovery job, but you should also do it regularly throughout the process of recovering refrigerant. Refrigerant recovery machines for HVAC
