-Liquid injection valves to insure sufficient compressor cooling during all chamber temperature conditions.
-Bypass systems for accurate temperature control while eliminating life-shortening rapid compressor cycling.
-Bypass time-out feature shuts compressor off, after timing out in a standby condition, reducing energy consumption and eliminating standby operation when profiles do not require cooling.
-Refrigeration pressure gauges on all systems.
-System design backed by years of environmental experience and constructed of high quality commercially available components.
HEATING SYSTEM
-Electrical resistance heaters are low mass open nichrome elements supported by ceramic insulators, for fast response and minimal residual heating effects.
-Heaters baffled from test space to prevent direct radiation on test specimens.
-Controlled by heavy duty, quiet mercury contactors rated for millions of cycles.
-Standard thermal links or electronic high temperature limiters with redundant heater contactor.

AIR CIRCULATION SYSTEM
-High volume, propeller type fan blades.
-Externally located fan motors with lubricated-for-life bearings.
-Integral one-piece stainless steel extended fan motor shafts for long life and minimal vibration.
-Chamber conditioning systems are interlocked to the air circulation system.
-Designed to minimize chamber temperature gradients and maximize conditioning system performance.

INSTRUMENTATION
-Microprocessor based programmer/controller on all chambers.
-User selectable Fahrenheit or Celsius temperature indication.
-Humidity setting and indication in units of percent relative humidity, eliminating the need for dry bulb/wet bulb conversion tables .
-Operator-oriented features for easy operation and programming.
-Digital indication of program and control parameters.
-Looping feature to allow repeating complete or partial programs.
-Guaranteed soak feature to let process variable reach setpoint before going to the next step.

-Real-time clock.
-Protection to retain controller parameters and programs in the event of a power failure.
-Three-mode controller action, featuring proportional band, rate and reset adjustment for optimal control.
