What Enviro Systems does
Enviro Systems, operating under the consolidated legal identity ACE Thermal Systems, is a US-based private aerospace supplier specializing in environmental control systems (ECS) and thermal management technologies for helicopters and fixed-wing general aviation aircraft. Founded in 1979 and headquartered in Seminole, Oklahoma, the company designs and manufactures the full ECS stack, including vapor cycle air conditioning, cabin pressurization, bleed air heating, and the underlying components such as bleed air valves, axial and centrifugal electric fans, temperature sensors and controllers, and air distribution valves. It complements this product portfolio with FAA Part 145 certified maintenance, repair, and overhaul (MRO) services, STC and PMA development support, and in-house validation and qualification testing against RTCA DO-160 standards, with manufacturing operations based in Thornton, Colorado.
The company sells exclusively to enterprise aerospace OEMs and operators through a direct, collaborative engineering sales motion, positioning itself as a single-source supplier from concept through in-service maintenance. Named customers include Airbus, Pilatus Aircraft, Honda Aircraft, Sikorsky, Textron Aviation (Cessna/Beechcraft), Bell, Cirrus Aircraft, and Piper Aircraft, spanning both rotorcraft and business jet platforms. Revenue is generated through two streams: hardware sales of ECS units and components on new aircraft production lines, and professional services revenue from aftermarket MRO, repair, and certification support.
Enviro Systems is a subsidiary of Signia Aerospace, a diversified aerospace conglomerate that also owns Hartzell Aviation, Hartzell Propeller, Cleveland Wheel & Brake Systems, Onboard Systems, Mezzo Technologies, and several other aerospace component brands. The combined ACE Thermal Systems entity was formed by merging two proven thermal management and ECS providers, pooling engineering, manufacturing, and certification resources. The business is AS9100 certified for design, manufacture, and maintenance, holds Part 21 manufacturing approval, and operates an FAA/ESA Part 145 Repair Station. Pricing is quote-based B2B with no public disclosure.
