What does a heater used on the recovery vessel expedite during the recovery process?

A heater used on the recovery vessel is designed to facilitate the transfer of liquid refrigerant by raising the temperature of the refrigerant within the vessel. When the temperature is increased, the refrigerant's vapor pressure rises, which helps to convert any liquid refrigerant into vapor more effectively. This process accelerates the flow of refrigerant into the recovery system, resulting in a more efficient and faster recovery process.

By helping the conversion of refrigerant from liquid to vapor, the heater also ensures that vaporized refrigerant can be handled effectively without causing the recovery unit to become too cold, which could slow down the recovery process significantly. Thus, the heater is instrumental in enhancing the transfer of liquid refrigerant during recovery, allowing for a quicker extraction and management of refrigerant from the system being serviced.
