Associated Environmental Systems offers a range of prefabricated, tight-tolerance environmental walk-in rooms that are easy to ship and install. Major features include:
 

Forced air circulation systems distribute air evenly and constantly recirculate it, maintaining uniform and accurate temperatures and humidity.

Temperature Ranges are from -60°C (-140°F) to +120°C (458°F ).

Refrigeration system meets the room\'s load demand and operates continuously in cooling mode. Single-stage mechanical units operate at -35°C and above and two-stage cascade units at below -35°C.

​Electric heating system provides very accurate and straight line control of temperatures. System is reliable and has a long life.

Humidity System choices are the conditioned fine Mist System or the Steam Generator System. Different ranges are available including special dehumidity ranges to 5% RH.

Prefabricated room construction consists of modular, sandwich-type panels with a metal skin inside and outside. Panels are easy to ship and assemble.

Multipane viewing windows can be ordered in custom sizes.

Incandescent or fluorescent lighting is vapor-proofed and sealed.

Instrumentation consists of single or two-channel microprocessor programmers with an accuracy of ±.25°C or better at the sensor. Other options include: RS-232C, RS-422A, IEEE-488 interface.

Safety standard is a redundant control circuit with its own controller and failsafe contactor. Many other options are available.
