ETS 5400-Series operating systems are the core of precise environmental control, providing humidity, dehumidification, heating, and cooling capabilities. Designed for use with ETS controllers, these systems can be used individually or in combination to achieve a wide range of environmental conditions.

While commonly used for ETS environmental chambers, 5400-Series systems are also available for upgrading existing environments or integration into custom systems. Each system offers unique advantages depending on conditioning time (short- or long-term), operational range, and the desired combination of environmental parameters (humidity, temperature, and duration). It’s important to note that the combined performance of multiple systems can exceed the individual specifications. Overall performance depends on the chosen operating system(s), chamber size, conditioning time, internal load, ambient conditions, and set points.

These systems support a variety of applications, including bench-top and floor-standing chambers, dry boxes, glove boxes, and desiccator cabinets with volumes up to 60 cu. ft. They can be configured for independent humidity control from <5% to >95% RH and temperature control from –40°C to 60°C, meeting the needs of most humidity and temperature applications. Compatible with ETS and other controllers and chambers, they are ideal for testing, weighing, calibration, assembly, storage, and R&D.
