Tenney ETCU Series Temperature Humidity Cycling Chambers
The Tenney ETCU Ultimate Series Temperature Humidity Cycling Chamber features scroll compressor technology that provides quiet operation, fast transition rates, and reliable operations.
The chambers incorporate a ceiling plenum to diffuse conditioned air vertically through the chamber. The top to bottom air circulation guarantees stable and consistent performance over the testing period.
Multiple heating and cooling systems are available, as well as a diverse list of options that together will create the chamber to accommodate your specific application..

Temperature Humidity Cycling Chamber Refrigeration System
The ETC Ultimate Series Temperature Humidity Cycling Chamber uses scroll compressors on all models up to and including 15 hp. The scroll compressor replaces standard, hermetic or semi-hermetic units, providing a more reliable system.
Unlike conventional compressors, which use about 15 parts to compress the refrigerant gas, scroll compressors use four moving parts. The compressors operate at lower internal temperatures. Fewer parts and lower temperatures yield less failures and an extended product life.
Temperature Humidity Cycling Chamber Humidity System
The humidity system is constructed of 100% non-corroding parts and is equipped with its own low water protection system. A transparent Pyrex vessel permits easy inspection and enables easy clean out and maintenance. The system operates at atmospheric pressure and is specially vented to prevent undesired siphoning.
Temperature Humidity Cycling Chamber Heating System
Low-mass nichrome, open wire heating elements are used to reduce thermal lag and provide rapid response to instrument demand. The heating elements are isolated from the workspace to reduce radiant influence on the test item.
Temperature Humidity Cycling Chamber Control System
The Pro-Touch control system uses modern, user-friendly touch screen technology that's powered by Windows CE. Environmental conditions within the chamber can be viewed in real time on the graphical display.
The Pro-Touch control system features:
- Built-in setup wizards and online help
- Standard Ethernet connectivity
- Bi-directional control
Logic circuits to select heating, cooling, and humidity modes.
