Sierra Lobo, Inc.

Sierra Lobo is a leader in researching, developing, manufacturing and marketing innovative products and processes for advanced cryogenic storage and thermal insulation systems, thermoacoustic cryocoolers, cryogenic instrumentation and electronics.

The Cryo-Tracker® mass gauging system measures and autonomously monitors cryogenic fluid conditions in flight tanks, stationary dewars and road-able dewars. The Cryo-Tracker probe (US Pat. No. 6,431,750) is an ultra-light liquid-level and temperature-sensing probe that provides accurate measurements, independent of liquid type, temperature and tank pressure.

The company has the skills and techniques necessary to design, fabricate, test and optimize multistage, large-scale pulse tube cryocoolers for applications including the following:

• Liquid hydrogen storage systems
• High temperature superconductivity refrigeration
• Propellant densification
• Compressed gas liquefaction
• Cryogenic refrigeration
• Zero boiloff

Sierra Lobo also offers systems analysis capabilities, including cryogenic tank system design and optimization, multilayer insulation system design, cryogenic reactant storage and fuel cell system design, as well as thermoacoustic codes DeltaE and REGEN 3.2 for pulse tube cryocooler design.
