Compact walk-in chambers for testing solar panels

The ENX112 chambers provide a test chamber large enough for testing full-size PV modules in the least amount of floorspace. Can be used for panels 1.2m x 2m or larger.

These models provide a variety of performance capabilities to meet maximum or minimum change rates in IEC or UL test standards. Incorporated are the features of our smaller Platinum and Global-N lines. The refrigeration systems of these models utilise modern, high performance scroll compressors that allow a small footprint while allowing unparalleled service access.

Performance acording to application

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.

Easy-to-use Programmer

In addition, the P-300 programmer makes running an ESPEC environmental test chamber a breeze. The full-color, touch-screen interface is remarkably easy to use and understand. The P-300 can be managed remotely via our new Ethernet/LAN-based Web Controller, serial port, or GP-IB/LabView.
