Isn’t an ECU just an HVAC unit?

Posted on August 16th, 2021

At its core, the acronym ECU is the military’s terminology for a heating, ventilating, and air conditioning (HVAC) unit, but key differences in mobility, ruggedization, and ability to face extreme temperatures put these into a category all their own. One common use of an ECU is to provide heated and cooled air to a shelter, […]
