Twin Variable Speed Booster Set – 100L/Min @ 4.5 Bar

The NT Cloke twin variable speed booster set is designed to provide consistent water pressure in properties where the incoming mains supply is insufficient or demand fluctuates throughout the day.

Delivering up to 100 litres per minute at 4.5 bar, this system is ideal for domestic properties, apartments, and light commercial environments requiring reliable pressure across multiple outlets.

Built with WRAS-approved stainless steel pumps, the system uses 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.
