VISION TEC

VT-ATHC series are altitude temperature and humidity chambers (Climatic vacuum chambers) for performing temperature and altitude condition testing in one combined test chamber more than one condition can be created simultaneously to satisfy many types of test requirements.

Our ATHC series chambers are designed to simulate altitude conditions up to 100,000ft. also offer simultaneous temperature/altitude and humidity testing from site altitude to 35,000ft.

VT-ATHC series are manufactured according to the Total Quality procedures, in compliance with the ISO 9001 standard.

General Features

1. Silent compressors using ecologically friendly refrigerants.

2. Air temperature variation and quick adaptation of specimens to it.

3. Friendly, flexible, up-to date control and management systems.

4. Allows easy servicing and upgrades.
