Gas control unit HP 257

The HP 257 is a dual stage panel for central gas supply with automatic changeover. It serves the safe supply of high purity and mixed gases from 2 single cylinders or cylinder bundles. The changeover sets in as soon as the pressure in the first side sinks below a predetermined level. This process is controlled by two installed regulators which are connected by their outlets. Two stage regulators will be used when a stable outlet pressure is required. The station is mounted on a stainless steel console and in standard version it consists of three pressure regulators and the in- and outlet gauges. Special characteristics: The HP 257 is a high flow changeover station for cylinders or bundles. Especially for gases with high requirements on purity up to 6.0, safety and density for which an uninterrupted supply overnight and weekends must be guaranteed. The supply concept can be optimised by options such as contact gauges and gas alarm boxes. Through our special cleaning system our pressure regulators are suitable for ECD – applications.
