While Enviro can provide everything from components to subsystems of an aircraft Environmental Control System (ECS), the best value for many OEM's is to purchase an ECS consisting of only a few prebuilt, pretested modules. Reduced part count, simplified purchasing, reduced installation time, and simplified troubleshooting are among the advantages of purchasing an integrated package.

Enviro engineers, working with airframer engineers throughout the design process, design a customized, integrated package containing valves, heat exchangers, controllers, and sensors. Exchanging solid models with the customer engineers, the system is designed to be easily installable, servicable, and to minimize installation space while maximizing performance.

For a fixed wing, pressurized, turbine powered aircraft, a system typically consists of a vapor cycle compressor drive, two or more cabin evaparator/fan assemblies, and an integrated Bleed Air Management Module (BAMM).
