The World's Smallest & Tiny Rotary DC Compressor
Only 1/17th of the volume, 1/11th of the weight compared to the reciprocating compressor.
Features and Applications:
RIGID has reduced the size and weight of the rotary mini DC compressor by about 1/17th compared with conventional compressors, which are about the size of a man's fist and work quieter than a library.
As a breakthrough technology, this 0.7cc tiny compressor could be applied to not just home appliances, but also outdoor equipment or cooling jackets to provide heat and cold.
Moreover, it is compatible with AC power for households and DC power for vehicles, so uses are expected to cover a broad spectrum, such as small medical, instruments, small fridges, small aircon, micro cooling, personal cooling, etc. will become even slimmer, quieter, and more energy-efficient or even be produced as portable refrigeration products that can be used at commercial & industrial use.
Drive Board (PCB Circuit)
The tiny compressor comes with our patent drive board, it is a 360° sine wave controller. That is, you can connect it to your software or computer to achieve multiple functions.
The RIGID rotary tiny compressor combines high-efficiency motor design, compression technology for minimizing refrigerant loss, nano-manufacturing technology, and control technology to achieve a 35% increase in efficiency.

Designed to optimize space and weight, mini compressors are perfect for small and mobile refrigeration. The small size of mini compressors makes them perfect for mobile or portable refrigeration, cooling electronics, and numerous commercial appliances where weight and space are important.
As a world leader in miniature refrigeration manufacturing, RIGID rotary mini bldc compressors are recognized for their reliability and quality, as well as for their excellent sound reduction and efficiency.
We are continuously developing our rotary compressors, not only to discover new technological advances but also to improve and reach our most successful results when operating them.
The BLDC rotary mini compressor features an optimal pump that operates quietly, while also providing excellent performance. In addition to heat pumps, air conditioners, and commercial cooling applications, this compressor is also well suited for various compact refrigeration applications.
Compared to traditional compressors, RIGID variable speed rotary compressors offer highly efficient and energy-saving features. Unlike a fixed-speed compressor that constantly runs at 100%, the Inverter Rotary Compressor delivers only as much air as it needs for cooling, saving significant amounts of electricity.
Your products will stand out. Your systems will be outstanding!
RIGID miniature compressors have the size, weight, and durability that make them well-suited to mobile or portable applications, including:
Direct Expansion Evaporator System Unit Frequently Asked Questions
1. What is direct expansion system?
Direct Expansion 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 is Direct Expansion Evaporatorin 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.
3. What is expansion system?
A direct expansion system 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.
4. How does a direct expansion system work?
The expansion parts (valve or capillary) controls 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.
5. 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.
6. 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 air, and the chiller units cool water. Chiller units cool water for use in other liquid systems like chilled water handlers.
7. 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.
