526 CD Series Switchover

Brass pressure differential switchover for high purity carbon dioxide or nitrous oxide
526D121-01-320 shown

The 526 CD Series Switchover is a pressure differential switchover system with a heated line regulator designed to deliver a continuous supply high purity carbon dioxide or nitrous oxide. The integral heaters in the line regulator ensure a high flow of inert gases that are prone to freezing due to flow or the Joule-Thomson effect. The switchover may be used with one cylinder per side or with a manifold that has increased storage capacity, like the CONCOA 52B (brass), 52C (chrome-plated brass), and 52S (stainless steel) Series maniflex manifold system. The CONCOA 526 CD Series switchover may be purchased with or without standard transducers, and with or without the Altos 2™ remote alarm.
