Built to deliver precise control of environmental conditions

ETC’s HVAC Low-Temperature Air Handler was introduced with the most extreme temperatures in mind. No matter the flow rate or temperature and humidity conditions required, the Low-Temperature Air Handler is built to deliver precise control of environmental conditions. The heavy-duty construction and rugged reinforced housing and access doors make the Extreme Temperature Air Handler the right solution for your extreme temperature air handling needs both indoors and out.


Easy maintenance and environmentally-friendly

The green design of the Extreme Temperature Air Handler ensures it is in line with an organization’s effort’s to reuse, repurpose and recycle. Easy maintenance eliminates the increased requirement for maintenance and/or repair. If space is limited and performance is key, ETC will design a system that meets or exceeds your environmental simulation needs.


User-friendly and sophisticated control system

The controls equipment provided is a sophisticated state of the current technology system for data collection, reduction, calculation and reporting. Sufficient data channel inputs are provided to monitor and control the Chamber. The application software package manages and maintains a database of UUT information, test points and profiles containing test suites. PLC control of the testing is monitored by the PC in a supervisory fashion allowing real time control and safety interlocking of the test process.
