CH Series

The CH Series Horizontal vessel is intended for low pressure transport and storage of liquid nitrogen, oxygen and argon. The horizontal configuration allows for large volumes of liquid to be portable and accessible at conveniently lower heights. This vessel was originally designed for interaction with LN2 liquefiers because of the low profile. Mounted on casters, a standard feature, movement within lab or plant operations is made simple and easy.

A unique support system is used in order to insure strength and durability without sacrificing thermal efficiency. The lowest possible heat leak is the driving force for the design of this product. Loss rates on this model have historically been lower than industrial products normally available. All vessels are fabricated with a stainless steel inner and outer jacket.

The standard configuration is supplied with casters for mobility, 2" bottom clearance for a lower profile, a 1.5" o.d. neck opening, located center top with a flanged termination. Two handles welded to the ends as well as lifting lugs round out the offerings. Maximum allowable working pressure for this vessel is 25 PSI. It is not a DOT or ASME certified fabrication. Sizes range from 300 liters to 2000 liters. The configuration of this vessel can vary significantly when options are added.

**Available Options**
	Top Mounted Plumbing Welded or Removable The standard manifold option is welded to the top neck. A removable style is available as well that allows access to the neck opening and inner vessel possible. The disconnect mechanism is a flanged assembly which is detachable without the use of tools. Included on the manifold are the liquid fill/withdrawal valve & vent valve, pressure gauge and two relief devices.”
	Differential Pressure Liquid Level Gauge This option adds the convenience of level determination without the use of batteries and an electrical connection.
	Self Pressurizing System A built in vaporizer supplies on demand pressure for large volume transfers or pressure maintainability for instrumentation. Standard units come with a regulator factory set at 20 PSI and a shut off valve for a vessel at rest.
	Front Mounted Plumbing For applications where top mounted plumbing cause height issues. The plumbing location gives the unit an even lower profile with a height reduction of 7".
	Auxiliary Access Port Top Mounted Located on the top of the unit with a flanged termination, this accessibility is an added convenience. It can serve as an additional fill or withdrawal port along with supplying accessibility to the inner vessel without disturbing of the working manifold.
	Skid Mounting A substitution for casters, supplies a way to mount vessels inside of trucks or concrete slabs.
Bottom Drain, Trapped with Valve (not shown) A gravity withdrawal option, another way to access liquid.
