Your first choice for a medium-size test chamber for PV module testing is ESPEC's ENX48.
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 utilize modern, high performance scroll compressors that allow a small footprint while allowing unparalleled service access.
The models come in different performance versions, depending on your planned use. More powerful performance allows you to complete the temperature-cycling test (10.11) faster, or with a maximum number of modules. There also is a 'damp-heat' (10.13) only model that saves you capital-cost and energy by having only minimal refrigeration.
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.

Energy-saving operation
Invisible to the end user, the P-300 uses advanced cooling control via an electronic expansion valve, saving energy and improving temperature stability. Sophisticated future-looking algorithms make temperature ramping faster and smoother. These high-end features are unique to ESPEC. Additional improvements in refrigeration and heater operation will make the next generation of ESPEC chambers the most energy efficient ever.
