We engineered a custom thermal cycling system with cold finger & electric heat that provides high vacuum operation and extreme temperature capability for large-format hardware testing. The 72″ diameter by 110″ long cylindrical chamber integrates an LN₂ cold finger for low-temperature performance and electrically heated channels cast into a large aluminum platen. The combined thermal design supports a –150°C to 150°C operating range. A dual-door layout enables the platen to roll out from one end of the chamber to simplify loading, inspection, and instrumentation. The HVC-3500 Thermal Vacuum Controller regulates temperature transitions, pump sequencing, and chamber operations, while the ruggedized mobile frame supports installation and service access.
LACO engineers can provide onsite engineering support and training to assist in setting up the device, ensuring there are no issues or errors, and training personnel on how to use the system.

Protect your sensitive equipment from contaminants during Ultra High Vacuum (<1-6 Torr) with an LN2-based Cold Finger. With simple integration via an ISO100 port, our LN2 Cold Finger captures outgassed materials and water vapor to ensure the safe, clean, and efficient operation of your vacuum system.
Protect your sensitive equipment from contaminants during High Vacuum (<10-4 Torr) with a refrigerant-based Cold Finger. With simple integration via an ISO160 port, the Refrigerant Cold Finger captures outgassed materials and water vapor to ensure the safe, clean, and efficient operation of your vacuum system.
The Frontier TVAC LACO Infrared (LIR) Bake-out Controller System gives you control of your vacuum chamber bake-out process. This system controls the power to the heat source and uses thermocouple feedback to regulate the temperature of the vacuum chamber. The heaters are small, high power quartz lamps that operate inside of the vacuum chamber. These heaters harness the radiant heat emitted by the IR lamps, enabling them to swiftly achieve surface bake-out temperatures compared to alternative surface heating methods.
LRS Cellular Remote Support Kit with 4G Cellular Connectivity is a small industrial VPN gateway device designed to offer easy remote access, across the internet, to LACO HVC and VC controllers. Kit includes:
The TITAN VERSA helium leak detector package is a proven solution using cutting-edge technology designed for leak detection of your TVAC systems. With its high sensitivity, the system can detect helium leak rates as low as 5×10-12 atm-cc/sec. Equipped with an internal dry membrane vacuum pump the TITAN VERSA achieves 2.5 L/sec helium pumping speed.
The TITAN VERSA is the only helium leak detector engineered and manufactured in the United States.
Thermal vacuum systems simulate the extreme conditions of space, enabling accurate validation of components, materials, and assemblies intended for orbital or deep-space missions. These systems also support thermal cycling, vacuum bake-out, and altitude simulation, allowing them to serve both space simulation and broader environmental testing needs.
Whether you are testing satellites, electronics, optics, or other mission-critical components, LACO’s TVAC platforms deliver repeatable, stable performance. In addition, every configuration aligns with NASA GSFC-STD-7000 and other key environmental test standards. As a result, your team can rely on LACO systems to support development, qualification, and pre-launch readiness with confidence.
