Environmental Control Units (ECU's) are designed for the stringent requirements of the telecommunications industry. Available in cooling capacities of 5,000 to 53,000 BTUH, the design of these units emphasizes a small footprint and quiet operation over an extended temperature range. The SlimPac, MiniPac and DoorPac units are built in a counterflow configuration. The ECUA11 is built in our standard top discharge design and is available in either the built-in economizer or closed loop (no outside air) configuration.

The ECUA59 & 60 solve the continuing problem of increasing heat loads in telecom shelters by providing additional cooling capacity with the same size return and supply openings as smaller capacity wall mount units. The ECUA59 has a nominal cooling capacity of 51,000 BTUH and matches to the same openings as our 2 ton air conditioners. The ECUA60 has a nominal cooling capacity of 53,000 BTUH and matches to the same openings as our 2 ton and 3 ton air conditioners.
