Circulatory Cooling Modules with Smallest & Portable Inverter Compressor

Circulatory Cooling Solutions

Rigid circulatory cooling modules are self-contained high-efficient refrigeration compressor with R134A coolant, smallest condenser and evaporator, filter drier and driver board etc. All these refrigeration parts are all well integrated in one unit, sophisticated design by our skilled engineers. The complete one piece unit not only facilitates installation but also assures the user of receiving latest, up to date construction.

The Compact Cooling Unit serves as a source of chilled water for circulation through the water pipes. It adopts Rigid patented tiny compressor provides powerful and sustainable cooling capacity, which enable your cooling device has constant circulatory cooling and without any limits. And the unit has smallest footprint and weight make it portability.

Small cooling system-Circulatory Cooling Solutions

Rigid Micro Cooling Modules have an extreme solutions. Chilled water is pumped from one small water reservoir throughout the vest or system via tubing or pipes. The temperature can be controlled or setted by users, and by the temperature of the water that you pre-setted in the small reservoir.

  • When extream cooling is needed in an intense situation or a tropical areas...
  • When Medical-Aesthetic devices request circulatory pure chilled water...
  • When Firefighting Works request highly portable cooling system...
  • When race car driver requires flexible and efficient cooling...

There is nothing more effective in the market than Rigid small cooling units to produce sustaining and efficient cooling capacity.
