EWSX282 Solar Panel Large Walk-in Chambers

Solid walk-in chamber designed for testing up to 20+ PV modules

Large Solar Panel Testing Chamber

ESPEC’s solid construction walk-ins are desirable for testing large loads of PV modules or panels at 85°C/85% as well as humidity-freeze and temperature cycling tests.  Hermetically welded seams and stainless-steel interior ensure integrity under extreme conditions required by IEC.

The models come in different performance versions, depending on your application. More powerful performance allows you to complete the temperature-cycling test faster, or with a maximum number of modules. There also is a 'damp-heat' only model that saves you capital-cost and energy.
