Gordinier Electronics 359 Cryogenics Timed Fill Alarm Controller 117V 50/60Hz

Gordinier Electronics 359 Cryogenics Timed Fill Alarm Controller 117V 50/60Hz

The Gordinier Electronics 359 is a benchtop cryogenics timed fill alarm controller designed to automate and monitor the filling of cryogenic vessels — most commonly liquid nitrogen (LN2) dewars used in laboratory, medical, and scientific settings. The unit allows the operator to set a timed fill interval (0–16 minutes), monitors probe and supply conditions, and triggers audible and visual alarms when attention is required. It controls an external solenoid valve through its rear-panel valve outlet, making it a complete automated fill and alarm management device for cryogenic systems.

Applications

The Gordinier Electronics 359 was designed for laboratory and scientific environments where cryogenic liquids — primarily liquid nitrogen — are used to maintain low-temperature storage conditions. These controllers are standard equipment in biological sample repositories, NMR/MRI magnet refill stations, cryostat systems, semiconductor research labs, and any facility that requires automated, timed filling of dewars or cryogenic vessels. The timed fill function allows unattended fills of a preset duration, while the probe input monitors actual cryogen level and the supply alarm notifies staff if the source supply runs low. Audible and visual alarms ensure that overfill, supply loss, or fill-cycle completion events do not go unnoticed — a critical safety and operational feature in any lab handling cryogenic liquids. Units of this type from Gordinier Electronics — a Michigan-based manufacturer specializing in cryogenic instrumentation — were widely used in university labs, hospital pathology departments, and industrial research facilities from the 1980s onward and continue to find use wherever legacy cryogenic dewar systems are still in service.
