Scope of Work for ATS Scientific Products ThermoJets and Recirculating Coolers

DRD # 3665

14 August 2024

United States ARMY DUGWAY PROVING GROUND

WEST DESERT TEST CENTER, CHEMICAL TEST DIVISION

DUGWAY, UTAH 84022-5000

1. Subject: Purchase ATS ThermoJets and Recirculating Coolers

2. Final Delivery Location: West Desert Test Center, U.S. Army Dugway Proving Ground, Utah.

3. Background:

a. This Scope of Work outlines the requirements for purchasing the ATS ThermoJets and recirculating coolers.

b. Currently WDTC, Chemical Test Divisions (CTD) uses the ThermoJets and Recirculating coolers to provide environmental conditions for several of our major test chambers/fixtures. These systems provide a wide range of high/low controlled temperatures critical to our test programs requirements.

c. The ThermoJets and Recirculating systems have been verified and validated (V&V) as the primary heating and cooling systems for test fixtures such as the SWATCH (SPITFIRE), and the Small Item Decon (SID) Chamber. These units will be the primary environmental controls systems for the newly designed SMARTMAN Boot & Glove and AVLAG Seams & Closure test chambers/fixtures.

d. The CTD established a process to keep common equipment items standard across the test chambers and fixtures. The ThermoJets and Recirculating cooling systems are two components that are common to all test systems and have been V&V by the testing community.
