Boosted gas pressure where the supply falls short
A gas booster lifts the pressure of the incoming gas supply so burners, boilers, and CHP engines get the pressure they are designed for. The Secomak 535/9 handles up to 500 m³/hr and up to 68 mbar.
It runs on natural gas, town gas, or biogas. The impeller is machined from a single piece of aluminium for smooth, balanced running, the bearings are sealed for life to keep out dust and dirt, and the fan chamber is ribbed for extra strength. It can link to a building management system.
The 535/9 comes as a stand-alone booster or as a package with controls and an installation kit, with APS Inverter, Duty Standby, acoustic enclosure, and Gas Sensor System options. Secomak is a British manufacturer that, working with British Gas, built the first gas booster in 1966. Each booster is built and tested in the UK to British Standard 8487.
