Double Door 35.2 Cubic Constant Temperature Walk-in Environmental Chamber
1. Walk-In Temperature and Climate Test Chambers
The KMHW series of walk-in temperature and climate test chambers are especially developed for large test specimens. Size and design mean optimal loading of test specimens. The modular construction and variability in size and equipment is ideally for costumerspecific application.

4. Description
Flexibility for structure
The panels used in our chamber are 4” (100mm or 150mm) Thick urethane-foam sandwiched between a stainless-steel interior wall and a coated-steel exterior. An assembled box is self-supporting. So that no heavy structural members are required. Different door sizes, flooring upgrades,access ports, and other modifications are possible.
Widest test range, most customizable
