Ydz Series Liquid Nitrogen Storage Tank Liquid Nitrogen Dewar 100L

The standard working pressure is about 0.05 MPa. The maximum allowable working pressure is 0.09 MPa. The primary safety relief valve opens at 0.099 MPa, and a secondary relief is set around 0.15 MPa. The tank should never be intentionally pressurized above its rated maximum working pressure.

YDZ tanks 100 L and larger come with a built-in float-type liquid level gauge. For smaller models, use a calibrated dipstick or time the fill from an empty state. LDH also offers optional digital level indicators for remote readout or alarms.

Yes, for short-distance transport on casters. For longer distances, secure the tank upright, relieve internal pressure first, and do not lay it on its side. Ensure proper ventilation in enclosed vehicles to avoid oxygen depletion.

The static evaporation rate is very low. For example, a 100 L tank evaporates about 1.3 L/day (1.3% capacity), and a 50 L tank evaporates about 1.0 L/day (2% capacity). Actual hold time varies with usage and ambient conditions.

Connect a cryogenic transfer hose from an LN2 source to the fill port. Open the fill valve slowly until the liquid reaches the fill level indicator or bottom of the neck. Close the valve and disconnect the hose. Wear PPE and follow the manual procedure.
