Compressor performance depends on operating speed and refrigeration system conditions. The published cooling-capacity, input-power and COP values are manufacturer test results under specified test conditions. Actual performance will vary with condenser temperature, evaporator temperature, airflow, expansion device, refrigerant charge and overall system design.

Important Note– Please Read Before Purchase· This listing is for the core components of a custom refrigeration system. It is not a complete plug-and-play refrigeration appliance.
· A complete refrigeration system may also require an evaporator, condenser, expansion device or capillary tube, refrigerant tubing, refrigerant charge, power supply, fans, fittings and other components appropriate to the application.
· The compressor and driver are designed to work as a matched set. Do not substitute an incompatible compressor or driver without verifying electrical and communication compatibility.
· The compressor driver uses TTL-level UART communication. It is not an RS-232 interface.
· The compressor driver requires an appropriate DC power supply capable of supplying the required current.
· Follow the wiring, operating limits, protection requirements and installation instructions in the supplied technical documentation.
· Performance specifications are test results under specified conditions and are not guaranteed values for every refrigeration system.
