Automatic Dewar Filling System

Automatic Dewar Filling ADF10 for unattended liquid nitrogen filling. This system is designed to automatically fill a dewar/mobile tank with liquid nitrogen from a piping system or bulk tank.

Automatic shut off for unattended filling
Fastest filling rate compared to any products in the market
Equipped with a user defined safety timeout feature
Provides a true liquid nitrogen fill
Eliminates liquid nitrogen waste

Here are some key advantages of ADF10:

Offers alternative filling using user-defined timeout based on Dewars capacity, ensuring accuracy, while providing flexibility for customized dewar filling.
Includes a safety leak check before filling, preventing operator injuries due to leaking liquid nitrogen from poor fittings.
Uses a Thermistor sensor instead of thermocouple. Thermistors experience such a large change in resistance per °C, which enables ADF10 to accurately differentiate cryogenic phases between liquids and vapor, allowing instant and accurate detection of liquid presence in vapor vent line to prevent dewar overfilling hazard.
Provides multiple inputs to override system automatic filling by external devices, including O2 safety monitoring systems, liquid weight measurements, liquid leak detection sensors, and emergency shutdown manual override capabilities.
24VDC dry output to connect auxiliary equipment like EMO valves or audible/visual alarms for emergency evacuation.
Incorporates a PLC and user interface display panel, providing visual text displays of alarm conditions or diagnostics situations.
