Triple Variable Speed Booster Set – 225L/Min @ 7.0 Bar

The NT Cloke triple variable speed booster set is engineered to deliver strong, consistent water pressure in buildings where the incoming mains supply is insufficient or higher pressure is required across the system.

Delivering up to 225 litres per minute at 7.0 bar, this system is ideal for multi-storey properties, larger residential developments, and light commercial environments where both high flow and high pressure are essential.

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.
