Enviro's military vapor cycle cooling systems are designed and qualified to the most demanding customer specifications. For these applications, systems must possess the ability to function reliably in the most severe environments.

Fixed Wing Passenger Compartment Cooling Enviro Systems manufactures 28VDC and 400Hz AC vapor cycle cooling systems (VCCS) for a variety of fixed wing military applications.

Rotary Wing Passenger Compartment Cooling Enviro's 400Hz, high capacity vapor cycle cooling systems provide passenger compartment cooling for a variety of military helicopter applications. These systems typically consist of one or more pallets containing the compressor, condenser, evaporator, and power controls. In addition to VIP applications for the US Presidential HMX-1 fleet's VH-60N's, the US Army's Military District of Washington's VIP fleet, and the US Navy's VH-3A fleet, and numerous head of state aircraft around the world, Enviro provides vapor cycle cooling for applications such as the US Army's HH-60L Medevac aircraft.

Ground Vehicle Passenger Compartment Cooling Enviro's 28VDC and 400Hz powered airconditioning systems have been adapted for a number of ground vehicle applications where harsh environments and/or light weights mean that commercial systems are not appropriate.

Special Mission Systems Enviro has a long history of providing specially designed systems for unique applications in aircraft R&D environments. In addition to providing cooling, vapor cycle refrigeration is sometimes employed to provide dry air to sensors and optics for these mission.
