LCHP-7-2 - Western Enterprises LCHP-7-2 Nitrogen Liquid Cylinder Manifold System

Technical Overview of the Western Enterprises LCHP-7-2

The Western Enterprises LCHP-7-2 is a specialized Automatic Analog System designed for the gaseous withdrawal of Nitrogen from liquid cylinders (dewars). Engineered for industrial environments requiring a continuous and reliable gas stream, this manifold system automatically manages the supply from two sources, switching from the primary to the reserve cylinder when pressure drops, thereby eliminating process interruptions associated with manual changeovers.

This system is specifically calibrated for use with liquid cylinders equipped with 350 psig relief valves. It features a maximum inlet pressure rating of 350 psig and a minimum inlet requirement of 250 psig to function correctly. The delivery pressure is user-adjustable between 40 and 210 psig, making it versatile for a wide range of pneumatic and purging applications. The "Analog" designation indicates a robust mechanical design that relies on pressure differentials rather than complex electronics, ensuring durability and ease of maintenance in harsh industrial settings.

Included in the package are two 72-inch nylon-lined cryogenic pigtails. These flexible hoses are designed to withstand the low temperatures associated with cryogenic gas withdrawal and are equipped with integral check valves to prevent backflow. The system is wall-mountable, with all necessary hardware provided, allowing for a clean and organized gas distribution setup. By automating the cylinder management process, the LCHP-7-2 enhances operational efficiency and safety.
