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 Systems 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.

Envirotronics will manufacture an ESS chamber to meet your specific environmental stress screening needs.

»Electrical Features:

  • Nichrome wire heating elements
  • Fail safe fusible link high heat limit protection
  • Door interlocks to prevent test interruption

»Instrumentation Systems:

  • Free standing consoles with 15 foot interconnect cables, additional lengths optional
  • Circular or strip chart recorders or System Plus(tm) for data logging
  • Redundant Temp Sentry available as product fail safe protection

»Air Flow Systems:

  • Externally mounted fan motors
  • Jack shaft assemblies on all systems to provide maximum reliability and flexibility
  • Aluminum backwards-inclined blower wheels
  • Vertical or horizontal air flow systems
  • High velocity air provides optimum air flow across your product
