If you’re a contractor or technician in the HVAC business, you know that refrigerant recovery machines are a must-have. Recovering and recharging refrigeration systems without one can be a dangerous and expensive undertaking. Refrigerant recovery machines are designed to remove and recover refrigerant from AC units while minimizing environmental impact. They also reduce refrigerant leakage into the atmosphere and make the job easier by reducing manual pumping pressures. There are many different types of refrigerant recovery machines available on the market. You’ll want to choose one that is easy to use and is compatible with the type of refrigerant you’re working with.

In addition to the right refrigerant recovery machine, you’ll need a set of hoses that are properly sized for your needs. The hoses should be UL recognized and rated for the pressure you’re working with. You’ll also want a large filter drier that can reliably sift out the contaminants in the refrigerant. These contaminants can cause a loss of capacity, so it’s important to keep them away from your recovery machine.

Another important consideration is a recovery tank that can be easily emptied. You’ll need a valve that allows the liquid to drain out of the tank, as well as a vent for releasing the air. You may also want to purchase a subcooling loop that helps the refrigerant cool down before entering your recovery machine. This can greatly increase your rate of recovery in high ambient temperatures.

You’ll also need a proper manifold set that is rated for the type of refrigerant you’re using. This will include a center utility port for recharging, as well as the standard blue and red low- and high-side ports. You’ll also need a set of service valves and core removal tools that are rated for the pressure you’re working at. If you’re doing push-pull recovery, you’ll need a sight glass that lets you see when the liquid line is emptying. When you’re finished, turn your recovery unit off and close the “liquid” valve on your recovery tank.

It’s a good idea to run a capful of oil (refrigeration or vacuum pump oil) through the recovery machine after every use. This will help to clear any copper particles or acids that may have made their way into the system, as well as keep the seals lubricated. Keeping your refrigerant recovery machine clean will ensure that it lasts longer and works at a higher level of efficiency. It’s worth the extra effort, as a poorly maintained recovery unit will slow down your work and can even damage the compressor inside the machine. Invest in a quality recovery machine, take the time to understand how it works, and follow the manufacturer’s recommendations to protect your investment. With the right refrigerant recovery machine, your business can be more productive and environmentally friendly. The best refrigerant recovery machines for HVAC are available at Berg Chilling Systems.
