Technical Requirements Document

The 16th Electronic Warfare Squadron (EWS/EWX) Advanced Programs (AP) test laboratory has a vital requirement for the following product to satisfy the mission. Laboratory testing of the defensive systems during Area of Responsibility (AOR) mission data file development enables the process to test, analyze, correct/improve and re-test in a long term organic environment.

The cost saving to the Air Force in organic laboratory testing is significant when compared and contrasted against a traveling to contractor facilities to build a mission data file and test at 16 EWS, Eglin AFB AP laboratory.

Equipment under test must remain at a specific cooling temperature and flow rates. Indoor air-cooled chiller/heater system with advanced temperature control technology allows full proportional cooling from 0% to 100% load conditions. With available temperature stabilities of ±0.05°C for critical applications, even with high cooling power requirements up to 70kW.
