DX Refrigeration System


RIGID DC Condensing Unit is a highly efficient and reliable component of a direct expansion (DX) refrigeration system.

The direct expansion system is an important part of the refrigeration system, using the direct expansion evaporator to produce refrigeration. This refrigeration is achieved through the direct expansion process, where the refrigerant is directly evaporated into gas and cooled, producing a cooling effect. The direct expansion evaporator is one of the key components of the refrigeration system and plays a critical role in the performance of the entire system.

RIGID DC condensing unit is the world’s smallest DX Refrigeration System which is assembled with a miniature bldc compressor. The dc refrigeration unit is easily integrated into customers’ applications to deliver efficient and effective direct cooling. The DC condensing unit is a versatile and durable solution for any direct refrigeration or small HVAC application. It is comprised of various parts, including a dc compressor, condenser, and capillary or expansion valve, all of which work together to produce the cooling effect.
