Stiral, an innovative company

About Stiral

STIRAL is an innovative company based in the Grenoble area. This French region is renowned worldwide for its scientific dynamism, that offers a breeding ground for the emergence of new technologies.

Pioneer in the design and manufacturing of microchannel heat exchangers, Stiral has developed a breakthrough technology with the ultra-compact heat exchanger Comhex©. Thanks to its smart design, microchannels are now available on the both sides of the heat exchanger. In other words, hot and cold fluids flow through channels with a hydraulic diameter below 500 \; \mu m.

Its high-performance design allows to reach, at reduced costs, a very large area density (above   3000 \; m^{2}/m^{3}).

Key benefits of Comhex©

The intensification of thermal exchanges, thanks to the innovative design, brings major competitive advantages. It helps improving:

  •  Compactness
  •  Low mass
  •  Wide operating range at high efficiency
  •  High energy efficiency
  •  Low refrigerant charge
  •  Safety
  •  Sturdiness
  •  Meet regulations
  •  Low noise levels

Comhex© is not only ultra-compact, but also highly flexible and customizable. Fluids can be both liquid and gas. It can be used as single-phase heat exchanger and two-phase heat exchanger (condenser or evaporator) as well. Whatever your application is, there will be a Comhex© design that fits in.
