The Enhanced Environmental Control Unit (E2CU) represents the latest in ultra-efficient, military ready, ducted unitary heat pump systems. It is designed to provide cooling, heating, and ventilation, and includes energy saving features such as compressor soft start, variable speed indoor blower, and microprocessor-based embedded diagnostics. These units were designed to replace the FDECU, LECU, and the IECU while providing better performance, reduced weight, improved power factor, simplified maintenance and increased reliability.

Mainstream’s E2CU has features not found in typical military ECUs. These enhancements include:

Plug-n-play wire harnesses
Microchannel evaporator and condenser
Non-corrosive easily replaceable forklift base
Sheathed wire harnesses
Machine threads, not sheet metal screws
Embedded diagnostics with microgrid compatibility for communication and control
