    Recirculating Chiller QD25H110


    Small recirculating chillers offer an economical, environmentally-friendly alternative to cooling with tap water.


  • Small & Compact Recirculating Chiller

    This is the best cooling capacity liquid chiller on the market for its ultra-compact size.

    Different from traditional water chillers, the QD25H110 is Air to Water Recirculating Chiller, which is a compact solution, designed to remove small heat loads from external systems such as from Peltier elements, batteries, medical devices, X-ray, materials and components, and beverage machines.


    The chiller QD25H110 combines a continuous flow of plate evaporator with a brand compressor to cool your application properly. It includes the core cooling components (compressor, condenser, expansion capillary, evaporator) and allows the end-user to adapt to the coolant fittings for ultimate flexibility.


    The recirculating chillers also help automate various chemical and scientific workflows and processes. Our compact chiller units have the smallest footprints and lightest weight, they are easily integrated into medical equipment or under laboratory benches.


    The QD25H110 features a compact footprint and is designed specifically for applications where the need thermal management systems that are compact, reliable, lightweight, and efficient. 


    Mini Water Chiller

    Recirculating Chiller QD25H110

    ​​Designed for small application refrigeration, the mini recirculating chiller combines excellent cooling performance, and a smaller footprint. Use a brand compressor (AC 110V-220V / 50-60Hz), the mini chiller unit is incredibly energy efficient and suitable for use all over the world. The low noise variable speed fans make the mini whisper quiet and the perfect addition to your laboratory or workplace.

  • QD25H110 - The Best Water Chiller & Smallest Size on the Market 


    RIGID is a miniature compressor innovation leader in China. We are creative and capture new technologies in compact cooling systems.


    The recirculating chiller - QD25H110, is a compact and most advanced cooling unit produced by RIGID. With a small footprint (similar to a laptop PC), it is easy to integrate into the end-user applications. It consists of 4 major components: a compressor, a micro-channel condenser, an evaporator, and a capillary. By using a brand AC compressor, it has low amps draw, and operates pretty quietly, which is ideal for the laboratory, where noise and space are concerns.


    Recirculating Chiller - QD25H110 is the ideal solution for cooling water for unique water process applications. The compact, modular configuration of the cooling components makes them perfect for many small liquid cooling requirements. This chiller unit's evaporator comes with inlet and outlet pipes and is ready for liquid connection to your application.
