About this file
This Statement of Work (SOW) outlines requirements for the U.S. Army Dugway Proving Ground's West Desert Test Center, Chemical Test Division to purchase environmental control equipment. Specifically, they seek to acquire 6 ThermoJet ES Environment Simulator & Precision Temperature Cycling Systems (Part #THJ80ES10000), 6 compatible flexible hoses (Part #CH6), and 6 ULT Recirculating Coolers (Part #RC211C0).
The ThermoJet systems must provide temperature ranges from -80°C to +225°C with ±1°C accuracy, dual-stage mechanical refrigeration, built-in grounded work surface, and microprocessor PLC-based PID controller with remote capabilities. The Recirculating Coolers must operate between -80°C to +75°C, with 880W heat removal at -60°C, include a 5-liter reservoir, and feature digital PID control with RS-232 interface. This equipment will serve as environmental control systems for test chambers/fixtures including SWATCH (SPITFIRE), Small Item Decon Chamber, SMARTMAN Boot & Glove, and AVLAG Seams & Closure test chambers, maintaining standardization across test systems that have been verified and validated by the testing community.

Scope of Work ATS Scientific Products ThermoJets and Recirculating Coolers
DRD # 3665
18 February 2025
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.
