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.
