Direct Expansion Refrigeration System Cycle
RIGID HVAC specializes in providing highly efficient and reliable refrigerated cooling systems. We have developed the world's smallest rotary compressor and offer custom solutions for various industries, including food, laser, medical, industrial, battery, electric vehicles, and military applications.
Notable products include AlphaCooler, designed for driver body cooling in racing and motorcycles, and compact Liquid Chiller, a core component for liquid refrigeration systems.
RIGID also excels in direct expansion cooling, simplifying system configurations, and maximizing efficiency, particularly in laser, semiconductor, and medical device applications. RIGID company's expertise and proven track record highlight its commitment to delivering compact, efficient, and durable cooling solutions.
DX System Cooling Cycle
Direct refrigeration systems operate by directly connecting the customer's evaporator. The evaporator, placed in the area to be cooled, cools the space by expanding the refrigerant in its coil and absorbing heat from the surroundings.
Examples of systems using this approach include mini-refrigerators, cooling for laboratory equipment, precision instrument cooling, and equipment that needs direct refrigerant cooling packages.
Direct Cooling Features
- 40% greater cooling capacity.
- Maintenance-free and factory-sealed.
- Improved efficiency and energy savings.
- Refrigerant flows directly through the cold plate.
- Smaller and lighter than traditional liquid chiller systems.
- Ideal for laser, semiconductor, and medical device applications.
- No need for pumps, reservoirs, or tubing, reducing potential failures and leaks.
- Simplified system for high reliability (mean time between failures > 90,000 hours).
Direct Expansion Evaporator System Applications
The RIGID Direct Expansion Evaporator System comprises miniature refrigeration modules cooled directly by refrigerants, leveraging RIGID's technology for a highly compact cooling solution.
These mini direct expansion systems easily integrate into compact, quiet, reliable, and cost-effective final solutions. Users have the flexibility to incorporate expanded cold plates directly into our expansion systems, enabling tailored cooling or precise temperature control for specific spaces.
RIGID's direct expansion systems find applications in various fields, such as mini-fridges, industrial settings, medical facilities, scientific laboratories, lasers, instruments, and other scenarios requiring active thermal management. The system, with a directly mounted cold plate, allows for precise temperature control with an accuracy of +/-0.5°C.
Thanks to RIGID's mini compressor, these systems can be exceptionally compact, making them ideal for high heat flux applications in electronics cooling, batteries, laboratory cold plates, and more.
