Model ET27-1-10-WC-HAF


The ET27-1-10-WC-HAF test chamber was designed to maximize the testing capabilities for 19″ rack mountable networking equipment.

It was designed with right-to-left cross-chamber air flow to work with customer product by moving the air in the same direction as current customer-completed chassis designs. This helps to eliminate temperature gradients between upper and lower test tiers found in typical environmental chamber configurations. All chassis are exposed to identical temperature swings, changes, and ramp rates. Additionally, this system was designed with a single stage compressor system for ESS compatible product testing requirements between 0° and 50°C.

The ET27-1-10-WC-HAF Test Chamber’s small size provides a much more flexible system by allowing more rapid load turn times and less impact during chamber down time for preventive maintenance.

The hole pattern in the side walls is characteristic of Techniks’ patented high-velocity horizontal air flow system.

All external connections typically found on other chamber designs such as water inlet/outlet and dry air purge systems have been moved inboard to protect them from accidental damage. Easy access for interconnect is provided through a 14″ x 12″ port which is conveniently located in the rear wall.
