Refrigerant recovery machines for HVAC help remove unwanted refrigerant from systems and transfer it to new cylinders for use in a different system. They help keep refrigerants out of the environment and reduce operating costs for businesses. They also keep technicians safe by reducing the risk of exposure to hazardous materials.
These machines vary in price and size, from small handheld units to larger commercial models. The best machines will be able to handle both liquid and vapor refrigerants, as well as multiple types of refrigerant. They will be capable of processing the refrigerant to prepare it for re-use, including filtering, moisture removal, and dehydration. Some will even be able to reclaim flammable refrigerants.
Before using the recovery machine, it is recommended that a technician evacuate the cylinder. This will help ensure that the cylinder does not have air in it, which can cause problems later on during the recovery process. In addition, it is important to keep the recovery tank cool. This can be done by placing it in an ice bucket or running a hose over the top of the cylinder.
Once the refrigerant is completely recovered and transferred into the cylinder, it is essential to purge the recovery equipment before moving on to the next job. This will clear out any copper particles or acids that may have made it past the filter drier. It will also keep the seals lubricated and working properly. This will help ensure that the recovery equipment is ready for the next job. Refrigerant recovery machines for HVAC
