An active/passive freezer system includes the capability to both actively cool a payload bay and passively maintain close to that temperature for extended periods of time; a freezer unit with a payload bay that can rapidly reduce its internal temperature; a thermal battery; a heat exchanger where liquid Nitrogen flows through; insulation that significantly reduces heat gain from external sources; and the capability to have separate units for cooling the payload bay and maintaining the temperature within the payload bay.

Active/passive thermal control system utilizing liquid nitrogen

A cryogenic liquid chiller includes a vessel; at least one heat exchanger, which heat exchangers function independently of each other and are comprised of at least one parallel flow path; a pump to circulate liquid within the vessel; a fill pump; and a drain pump.

Cryogenic liquid chiller with multi-fill points optimized for efficiency, capability, and versatility

The present invention is a high-performance ultra-low temperature chest freezer capable of reaching temperatures as low as &#x2212;160&#xb0; C. within several hours with the capability to automatically and continually defrost and dehumidify its payload bay before, during, and after a door open event without needing to cease freezing operations or raise the setpoint.

High performance ULT chest freezer with dehumidification

An alcohol-based solvent chiller includes an insulated vessel; a spiral-shaped heat exchanger designed specifically to chill alcohol-based solvents that become viscous at low temperatures within the insulated vessel; a cryogenic tank with pressure building capability that will force coolant through the heat exchanger at a specific pressure; and a cryogenic pump to circulate viscous cryogenic temperature liquids within the insulated vessel.
