RIGID Mini Water Chiller
RIGID, based in China, is a pioneering force in miniature compressor technology, driving the development of high-performance, compact cooling systems. With a commitment to cutting-edge innovation, we are reshaping the future of cooling technology across industries.
Our Mini Water Chiller is built around four essential components: a miniature compressor, micro-channel condenser, evaporator, and capillary or expansion valve. The plate evaporator serves as the core heat exchange module, efficiently transferring heat from refrigerant to coolant in a highly compact design.
The refrigerant absorbs heat generated by the fluid, facilitated by a circulating pump that directs liquid flow through the evaporator and connected tubing.
This miniature water chiller offers a host of advantages, including an ultra-compact radiator and superior heat dissipation. Designed for environments where space and weight are limited, it uses a mini compressor to achieve an incredibly lightweight, space-saving cooling solution. The Mini Water Chiller excels in precise heat transfer, making it indispensable for applications with strict space and weight constraints.
RIGID provides reliable liquid cooling solutions that blend compactness, affordability, and easy integration into various systems. Explore our extensive range of products. If you don’t find what you need, reach out to us at info@rigidhvac.com or call +86 579 8837 9768 for tailored solutions.
