Compact Walk In Environmental Chamber

Compact Walk In Environmental Chamber


JOEO compact walk in environmental chamber is used to test full-size solar panels or other large products Performance to meet IEC 61215, 61646, UL-1703 and similar test requirements,Widely used in industries such as electronic products, PCBs, semiconductors, automobiles, aerospace, etc
10.11 Temperature cycling
10.12 Humidity freeze
10.13 Damp heat



  • Compact Walk In Environmental Chamber  provide a test chamber large enough for testing full-size PV modules and other large products in the least amount of floorspace. Can be use for panels 1.2m x 2m or larger.
  • JOEO walk in environmental chamber 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 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.

Structural Features


  • Ideal for high temperature & high humidity applications,High temperature range to 150°C.
  • Suitable for change rates greater than 10-20°C/min.
  • Integral welded floors provide proper drainage of water/liquids.
  • One piece construction make the chambers easy to install.
  • Larger units can be constructed on site.
  • Walk in environmental chamber is a high-efficiency refrigeration system that provides unmatched performance; it features optimal temperature and humidity control accuracy for precise testing results, faster ramp. rates, and up to 40% energy savings.
  • The user interface allows you to program, control and monitor your tests at any time and anywhere – even from your tablet or smartphone.
  • Optional module rack with rollers
         Size 1: rack can hold 1.2m x 2m panels
         Size 2: rack can hold 1.2m x 2.4m panels
         Size 3: rack can hold 1.8m x 2m panels

Temperature and Humidity Control

JOEO walk in environmental chamber Control systems are designed with the proper heating, refrigeration, and humidity control to achieve your desired performance and capabilities. The Control systems simply rolls-up to an assembled panel chamber to complete installation.
Also,touch-screen controller can be managed remotely via our new Ethernet/LAN-based Web Controller, serial port, or GP-IB/LabView. USB access is standard.

Energy-saving operation

Invisible to the end user, 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 and highly appreciated by our customers with this type of large environmental temperature chamber.
