ince being launched in 2014, Lowara’s GHV boosters – now locally marketed as eXpress boosters – have been in high demand. The booster sets are fully automatic for water supply, water pressure increase, and water transfer in buildings, industrial and allied applications. The Lowara eXpress series operates in conjunction with the Xylem
Hydrovar® pump controller and is capable of delivering up to a 70% saving on energy bills. To reduce delivery times, Xylem South Africa has invested in fabrication and assembly facilities in South Africa, reducing the waiting period of eight weeks by more than 75%. Delivery times are confirmed at the time of order placement. “Xylem's Lowara eXpress boosters are a hit with our customers because they provide excellent value,” says Vinesan Govender, engineering manager: Africa, Xylem. “Xylem Africa can now deliver eXpress boosters to customers in less than two weeks and continue to support installation and maintenance through our vast domestic presence and partner network.” Xylem Africa has localised the assembly of six models within the eXpress booster set series.

control panel – all mounted on a frame for easy installation. This series is easy to program, designed for maximum energy efficiency, and can communicate with a BMS system via Modbus or BACnet. End-users benefit from a host of features, including dry-run protection, low noise, small plant room footprints, no large pressure vessels, soft-start, no hydraulic shock, autochangeover, fault history, protection against under-/overvoltage, and backflow protection through the use of a Cat 5 break tank type A/B air gap. It has a timed-delay fill mode, which ensures the pumping system does not flood the building on start-up during a power failure due to the hydraulic surge.
