Gas control unit HP 252

The HP 252 is a single 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 through one mutual housing. The station is mounted on a stainless steel console and in standard version it consists of two pressure regulators and the in- and outlet gauges. Special characteristics: The HP 252 is a special version of a typical cylinder station with automatic changeover. It combines two pressure regulators which are placed in sequential position in one housing to save space. Especially for gases with high requirements on urity 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.
