Improved Environmental Control Units (IECU)



Each size/type IECU will be assigned a separate line item number and will be available as a separate item in accordance with the basis of issue of the supported system. The IECUs will be supported under the existing maintenance structure. The need for IECUs that are lighter, more reliable, consume less power, employ modern control/logic systems, reduce in-rush current and meet statutory ozone depleting chemical requirements is shared by all services. The IECUs will replace legacy MIL-STD ECUs in form, fit and function regardless of inventory type.

The primary shortcoming for existing military standard (MIL-STD) ECUs is that they utilize ozone depleting hydrochlorofluorocarbons (HCFC) refrigerants, namely HCFC-22. This ozone depleting chemical (ODC) has been regulated according to a specific schedule that prohibits manufacturing of new equipment using the ODC after 1 January 2010, and bans its use altogether by 1 January 2020 for servicing of existing equipment. These phase-out dates occur much earlier in some allied nations where the U.S. Army must continue to operate.

The MIL-STD ECUs consume substantial amount of power from military generators and the generators in turn consume large amount of fuel. One of the goals of IECUs is to reduce the power consumption so that each IECU can be powered by smaller size generators, which will consume lesser fuel. Lighter IECUs will also contribute towards the overall system’s weight reduction, allowing more agile and easily moveable Army. As an example, the following table shows smaller size MIL-STD ECUs vs IECUs and which generators are currently required and will be required in the future:
