RIGID is the miniature compressor innovation leader in China. We keep looking for novel solutions in compact & portable refrigeration technology.
Since 2010, RIGID has been at the forefront of discovering innovative solutions for compact and portable cooling technology. With over a decade of dedicated investment in micro refrigeration design and over 100 successful customer projects, we bring extensive expertise to the table.
RIGID DC Condensing Unit is directly in contact with the user's evaporator or a cold plate. In fact, with no secondary coolant needed, the system only requires minimal parts. There is no necessary to circulate cool air or to circulate coolant with fans or pumps. Because these additional parts add complexity and inefficiency. The DC condensing unit's major advantage is to get rid of most ductwork and piping, and their ease of integration into the user's equipment.
The DC Condensing Unit is also named the direct expansion system. It typically offers the highest heat transfer rates. It is an ultra-compact chiller by assembling with a mini dc compressor. The direct expansion system use R134a or R290 refrigerant. And the mini compressor drives the refrigerant directly through the evaporator, so that the refrigerant absorbs heat directly at the heat source, minimizing the size and component count of the system.

1. What is DC Condensing Unit?
-DC Condensing Unit is also named Direct Expansion. It means that the refrigerant expands to produce the cooling effect in a coil that is in direct contact with the conditioned air that will be delivered to the space.
2. What Components Included In DC Condensing Unit?
-RIGID DC Condensing Unit is consist of a mini compressor, controller, condenser, capillary, filter drier, as well as other small refrigeration parts.
3. What is Condensing Unit Evaporator in mechanical engineering?
-A direct expansion refrigeration unit, also known as a condensing unit, uses condensed refrigerant liquid to cool the air in a given space. It is widely used in micro refrigeration, small refrigerators, mobile freezers, medical, laser, precision instruments, laboratory equipment, etc.
4. What are RIGID DC Condensing Units Advantages?
-RIGID DC Condensing Unit System consists of an environmentally friendly Refrigerant, R134A, R290 or R1234yf. It is built of Brushless Compressor and driver board, micro channel condenser, and highly efficient dc fan. The DC Condensing Unit is the optimized combination of efficiency, reliability, and ultra-compact size.
A DC brushless motor powers the compressor and is available in DC 12V/24V/48 versions. Additionally, due to its small size, high reliability& efficiency, the direct expansion system has found numerous applications, particularly in medical devices and other small refrigeration equipment.
5. How does a DC Condensing Unit system work?
-The expansion parts (valve or capillary) control the flow of refrigerant into the evaporator coil. Hot air is extracted from the specific space and blown over the heat exchange coil by the evaporator/indoor fan. The refrigerant in the coil absorbs the heat and expands. This lowers the temperature of the air being blown into the space/room.
6. What is the main function of an expansion valve or capillary?
-The expansion valve removes pressure from the liquid refrigerant to allow expansion or change of state from a liquid to a vapor in the evaporator. The high-pressure liquid refrigerant entering the expansion valve is quite warm.
