Environmental Chambers for Solar Panel Testing

EWS chambers are solid, one-piece construction, using fibreglass insulation and an angle-iron frame. The stainless steel interior liner is reinforced and continuously welded, including leak-testing for integrity.

Our chambers are compliant for the following test methods:

  • Thermal Cycle Test
    Requires temperature cycling between 85°C and -40°C, 50 or 200 times
  • Humidity Freeze Test
    Cycling between hot/humid 85°C/85%rh and subfreezing -40°C ten times, with extended soaks at 85/85
  • Damp Heat Test
    A long term, 1,000 hours, test at 85°C/85%

ESPEC chamber only for Damp Heat Testing is also available.

(Conventional chambers, like our EWP models, are built using panels with foam insulation that cannot withstand higher temperatures and are more susceptible to leaks at the seams under extreme conditions, such as fast temperature cycling.)

The angle-iron frame provides enough structural strength to allow a full-opening door for easy loading of large arrays without restriction. A full-opening door can also allow floor-space saving over panel chambers.

Easy-to-use Programmer

In addition, the SCP-220 programmer makes running an ESPEC environmental test chamber a breeze. The full-color, touch-screen interface is remarkably easy to use and understand. The SCP-220 can be managed remotely via our new Ethernet/LAN-based Web Controller, serial port, or GP-IB/LabView.
