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.
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.
