RIGID: Your Premier Small Direct Cooling System Supplier

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.

This concept eliminates the need for a water cooling loop (water pump, reservoir, and associated tubing) resulting in a greatly simplified cooling system. RIGID dc condensing unit is the world’s smallest air direct cooling system, and it can integrate directly into a customer’s compact systems and provide very high heat fluxes at the heat source.

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 or R290. 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. What are RIGID DC Condensing Units Features?

RIGID DC Condensing Unit is a new concept in the refrigeration industry, designed for portable & compact direct refrigeration applications. It is a micro-cooling solution available for reach-in freezers and refrigerators in personal and commercial use, and professional medical refrigeration applications. It also provides outdoor study/operations with several other benefits, as its portable and compact concept offers flexibility and its pocket-size function, allowing users to take it from one place to another.

The DC Condensing Unit can easily install and has sound performance in applications such as portable fridges, medical cooling, laser cooling, direct refrigeration, cold plate, and other equipment. RIGID dc cooling kit is widely used for compact and micro air cooling devices.

6. How Much of DC Condensing Unit Cooling Capacity?

The dimensions are incredibly small for a system with over 360W of cooling capacity. In some portable refrigerators, this system can be easily integrated into refrigeration applications. It is the most efficient cooling system in the market requiring only a small volume of the portable fridge of electrical power for maximum cooling.

7. What is RIGID DC Condensing Unit?

RIGID DC Condensing Unit enables the most compactly designed refrigerant system. A direct expansion system eliminates the use of a secondary coolant loop and uses the refrigerant to directly cool the desired payload via a cold plate. In a DX system, the evaporator absorbs heat directly from the payload.

8. 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.

9. What is the difference between indirect and direct cooling system?

In cooling systems, the distribution can be either direct or indirect. If direct, the cooling water goes directly into the internal piping system of a building. In an indirect system, a heat exchanger separates the internal from the external system.

10. What is the difference between DX system and chilled water system?

The immediate and most noteworthy difference between these two units is that the DX (direct expansion) unit cools the air, and the chiller units cool water. Chiller units cool water for use in other liquid systems like chilled water handlers.

11. 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.

12. Why Choose Rigid DC Condensing Unit?
  • Stationary or portable available.
  • Minimize weight & footprint & noise.
  • Compact refrigeration unit for precise thermal control.
