FlexAir® products include several systems that provide thermally-controlled environments for electronic equipment and batteries within a telecom shelter. Comprised of direct air cooling systems, heat exchangers, battery cooling systems, and heaters, FlexAir solutions are designed to complement FlexSure®, SiteFlex®, StreetFlex® and VaultFlex outdoor enclosures and shelters.

An advanced cooling system family

The FlexAir family of products include the FlexAir Green Free Cooling System (GFCS) series and the FlexAir IsoCool® system. With the FlexAir GFCS series, cooling capacity is managed based on the temperature difference between the interior and exterior of a shelter, as the system measures heat load and degree of pollution in the inlet air filter. FlexAir IsoCool is a standalone battery cooling system that creates a temperature zone for backup batteries that is lower than the ambient temperature in the shelter.

  • Optimized for energy efficiency
