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.

Get improved performance, energy savings, plus USB access

New P-300 controller with USB

The exclusive ESPEC P-300 controller has USB and Ethernet features to make programming and data collection easier than before. The user interface uses tabs for faster access to any screen. Standard USB and optional Web Controller/Ethernet interfaces make programming and data acquisition much simpler. In addition, improved algorithms make operation faster and smoother.

DEMO: See how easy the P-300 is

USB port for upload/download of test profiles and test data

  • Test programs can uploaded or downloaded from the P-300 via USB thumb drive.
  • Create, edit, and store programs on a PC using the included Pattern Manager Lite software.
  • Accurate, repeatable testing by uploading the same program to multiple chambers.
  • Create your own back-up archive of programs, and get additional profiles from ESPEC's library.
  • Retrieve and download test operation data via USB thumb drive. Data timeframe is selectable.
  • For integrity, viewing test data on a PC and exporting to Excel requires included Pattern Manager Lite software.

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.

Additional capabilities

  • Store up to forty programs, as well as three different constant-mode set-ups.
  • Multilingual display in English, Japanese, Chinese, or Korean.
  • Alarm diagnostics and history, plus a ‘back trace’ feature for troubleshooting.
  • Three programmable timers allow the user to set reminders for maintenance or other actions.
  • Energy saving by using only one compressor when testing above -10°C (for cascade refrigeration models).
  • Optional Ethernet/browser-based Web Controller access can also be used to upload and download programs, as well as data.
  • Optional Product Temperature Control allows faster ramping to the desired conditions on the sample.
  • Computer interface options for specialized programs: RS-232/serial or GP-IB.
