Cylinder station

2x1 cylinder (bundle) dual stage with automatic changeover – side by side version

The HP 255 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:
It is a very compact design of an automatic changeover cylinder station.

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.

To identify the correct order code for your HP255

Start with "HP255-", then add the appropriate number options from columns A, B, C & D  in the table below followed by the gas to be used.

HP255-2-1-1-1-Argon specifies a HP255 model in brass with 200 bar inlet pressure, 0.1 - 1 bar outlet pressure & standard gauges, for use with Argon gas.

Material Inlet pressure (p1) Outlet pressure (p2) Gauges
1 = stainless steel 1 = 200 bar 1 = 0.1 - 1 bar 1 = standard gauge
2 = brass 2 = 300 bar 2 = 0.1 - 3 bar 2 = contact gauge ex
    3 = 1 - 6 bar  
    4 = 1 - 17 bar
