Improved Environmental Control Unit (IECU)


Mainstream’s modular Improved Environmental Control Units (IECUs) provide heating and cooling to troop shelters, containers, vehicles, and communications enclosures in ambient temperatures as high as 140°F and as low as -50°F. The IECU is available in three different nominal cooling capacities (9,000, 18,000 and 36,000 Btu/hr) with multiple power input options. Designed to replace legacy R-22 based ECUs, the IECU features improved energy efficiency, lighter weight, and easier maintenance. The IECU uses environmentally safe R-410A refrigerant and meets or exceeds all requirements for military heating and cooling.
