Portable Dewars for Liquid Nitrogen, Oxygen & Argon

CL/CLPB Series

liquid nitrogen, liquid oxygen, liquid argon
liquid nitrogen tank / portable dewars

The CL/CLPB is an ideal liquid nitrogen (LN2) tank that works equally well with liquid oxygen or liquid argon. This line of portable cryogenic vessels is intended for low pressure transport and storage with conventional straight liquid dispensing.

These tanks ready to roll with sturdy construction and casters. An easy-to-read differential pressure-type liquid level gauge, full tricock valve and relief devices make the vessels safe and easy to use.

For the ultimate in transfer efficiency, the CLPB tanks add a self-pressurizing system that eliminates the need for external pressurization equipment.
