Model ESS Series -Environmental Stress Screening Chambers
The Envirotronics ESS line of Chambers are designed for environmental stress screening applications. ESS systems can be designed in reach-in or cart-based versions based on your requirements.The ESS Series allows highly accelerated product temperature change rates through high air velocity conditioning. Due to the wide variety of products being tested, Envirotronics has developed standard models that feature either our patented horizontal or vertical air flow. Today`s customer demands dictate that different temperature ranges as well as change rate capabilities be offered. Envirotronics will equip your system with single-stage, cascade, twin-screw, LN2 boost, or LN2 cooled refrigeration systems. The powerful Envirotronics Solutions Plus(tm) Controller/Programmer is standard. By utilizing Quick Draw, we ensure that your product reaches set point as quickly as possible to reduce cycle times.
