Liquid Nitrogen Tanks

CL/CLPB Series Dewars, Ideal for Cryogenic Storage and Dispensing

liquid nitrogen tank sizes

CL and CLPB liquid nitrogen tanks are portable, safe, and convenient storage that works equally well for liquid argon or liquid oxygen. The CL Series tanks are not pressurized, while the CLPB tanks are self-pressurizing.

Portable, Sturdy Cryogenic Tanks

Both the CL Series and the CLPB Series cryogenic dewars are intended for low-pressure transport and storage with conventional straight liquid dispensing. These sturdy tanks are ready to roll, they are made of stainless steel and designed with handles and weight-appropriate casters. Larger capacity tanks have pull handles.

Safe and Efficient

An easy-to-read differential pressure-type liquid level gauge makes it convenient to monitor the pressure in the vessel, a relief valve provides an extra measure of safety. The tank’s vent valve has a full tri-cock configuration to guard against over-filling.

CL and CLPB tanks feature convenient fill/withdrawal valves making them ideal for dispensing cryogens like liquid nitrogen. For the ultimate transfer efficiency, the CLPB tanks add a self-pressurizing system that eliminates the need for external pressurization equipment.
