1. Working Principle
The gaseous refrigerant in the refrigeration system is sucked in and compressed into liquid by a compressor, and the refrigerant is collected into a specific container through filtration, separation and other treatments. Some equipment also has a purification function to remove impurities, moisture and non-condensable gases in the refrigerant for reuse.

2. Product Features
Efficient recovery: It has a high recovery rate. The recovery volume of different models ranges from tens of kilograms to hundreds of kilograms per hour. It can quickly complete the refrigerant recovery work and improve the repair and maintenance efficiency.
Precise control: Equipped with pressure, temperature and other instruments, it can monitor the parameters in the recovery process in real time, which is convenient for operators to accurately control the recovery process and ensure the safety and effect of recovery.
Strong compatibility: It can be applied to a variety of common refrigerants, such as R134a, R22, R407c, R410a, etc., to meet the recovery needs of different refrigeration equipment.
Safe and reliable: It is equipped with multiple safety protection devices, such as overload protection, high-pressure protection, etc., to prevent equipment damage under abnormal conditions and ensure the safety of operators. Some equipment also has a leak-proof design to reduce the impact of refrigerant emissions on the environment.
Easy to operate: The operation interface is simple, and some equipment has automatic functions, such as automatic shutdown and automatic detection, which reduces the difficulty of operation and is convenient for non-professionals to use.
