Tenney Ships Environmental Walk-In Chamber to a Manufacturer of Consumer Products

Posted: Feb 19, 2018

Tenney announced the shipment of an environmental walk-in chamber to a manufacturer of consumer products. The walk-in room will be used for R&D environmental testing of products prior to going to market.

The maximum temperature rating of the test chamber is 80°C with an operating temperature range of 0°C to 80°C. The walk-in chamber has work chamber dimensions of 119.5” W X 123.5” D X 102” H and ±5.0% humidity control after stabilization based on an empty chamber. The relative humidity range is 20%-95% RH in the temperature range of 20°C to 80°C limited by a 5°C dew point.

The chamber air temperature is capable of transitioning from 0°C to 80°C and from 80°C to 0°C at 1.5°C per minute on average based on an empty chamber and zero live load present. The environmental walk-in room utilizes vertical air circulation and the air heating is provided by a series of electric heaters isolated from the working interior to prevent direct radiation.

The mechanical refrigeration of the room is a single stage type that utilizes one 5 HP semi-hermetic reciprocating compressor R507 refrigerant. The system features an air-cooled condenser system and operates continuously when cooling is needed. The refrigeration controls provided achieve capacity modulation as required.

“We installed a dry air dehumidification system on this walk-in room to dehumidify the chamber to dew point levels below those attainable by the refrigeration system. This feature provides controlled humidity operation in the chamber that can obtain humidity levels down to approximately 5% RH with temperatures down to + 20° C (+ 68° F).” ~Mike Shaw, Regional Sales Manager

Unique features of this environmental walk-in room include:

  • Synergy NANO control system with total programming capabilities.
  • Process inputs include RTD, thermocouple, voltage and current
  • Dry air dehumidification system
  • TempGard IV over/under temperature protection system
  • Cam-action locking devices
  • Maximum floor loading of 600 PSF
  • 304 stainless steel interiors
