Triple Variable Speed Booster Set – 480L/Min @ 3.5 Bar

The NT Cloke triple variable speed booster set is designed to deliver consistent water flow and pressure in buildings where the incoming mains supply is insufficient or demand is high across multiple outlets.

Delivering up to 480 litres per minute at 3.5 bar, this system is ideal for larger residential developments, commercial buildings, and applications where maintaining strong flow is critical.

Built with WRAS-approved stainless steel pumps, the system uses advanced variable speed inverter control to automatically adjust performance based on demand. This ensures stable pressure, improved energy efficiency, and reduced wear on system components.

Supplied as a fully assembled and pre-tested package, the booster set includes pumps, pressure vessel, controls, and fittings for straightforward installation.

In the event of water supply interruption, the system features dry run protection with automatic shutdown and restart functionality to safeguard the pumps.
