Wilo has launched its new CAT5 Booster set into the marketplace. UK water regulations – G6.1e – states that non-domestic hose union taps cannot be fitted directly to the water supply. It is essential to incorporate a backflow prevention device to ensure no back flow and syphonage leading to contamination of the potable water supply by bacteria returning up the hose pipe into the mains water supply.
The new Wilo CAT5 booster set incorporates a 115 litre polypropylene break tank which is supplied complete with a WRAS approved AB air gap. The overflow and weir are screened to enable connection to hygienic systems.
Applications for this equipment include such uses as non domestic hose union taps, bin and vehicle washdown, garden irrigation, laboratories, mortuary and embalming equipment, butchery and slaughter-house equipment.
The units are supplied with either a single fixed speed pump or a variable speed pump as specified. The single speed sets are controlled via a pressure switch, DOL motor starter and a run on timer, whilst the variable speed sets are controlled via a pressure transducer and motor mounted inverter.
The booster set monitors the system pressure and as demand increases the pressure will fall and the pump will start and continue to run, until demand has stopped and pressure increases to the set point. The fixed speed booster sets have a run on timer that overrides the pressure switch for a set period to minimise the number of starts per hour.
