Walk-in Environmental Temperature Humidity Chamber Assembled and Integrated on-Site

Application :
   OTS Walk-In Chamber serves as a test site for large components, assemblies, and finished products in electrical and electronics, aerospace, batteries and automobiles, etc
   OTS manufactures both Static Walk-In Chambers and Dynamic Walk-In Chambers and can be configured as a temperature chamber or a temperature humidity chamber.

   OTS-Series walk-in temperature and climate test chambers are especially developed for large test specimens. Size and design are optimal loading of test specimens. The modular construction and variability in size and equipment is ideally forspecific application.
