Extreme low-temperature testing down to 4K — liquid nitrogen and liquid helium cycling for simulating cryogenic fuel systems and space thermal environments.
Description
Experior Laboratories offers liquid nitrogen and liquid helium cycling and exposure for test temperatures down to 4K (-269°C), simulating thermal exposure conditions found in liquid oxygen and liquid hydrogen fuel systems common on upper-stage spacecraft. Test setups use a double-wall vacuum-jacketed immersion dewar with multi-layer super insulation, a baffled reflective top cap, and flexible vacuum-jacketed liquid helium transfer lines to minimize heat transfer. Safety systems include triple-redundant overpressure relief, a shutoff valve on liquid helium transfer lines, and environmental oxygen sensors. Applications include connector/cable harness immersion testing, valve and seal performance during liquid propellant flow, thermal management system simulation, solar cell efficiency testing, and structural materials testing for orbital systems.
