C99 Compressor Control Box

Description:

The microprocessor-based Control Box controls the compressor mass flow based on the required temperature or pressure value. It was designed to operate only with the C99 externally controlled compressor. The compressor is equipped with a low pressure sensor and a combined discharge pressure and temperature sensor.
