Triple Variable Speed Booster Set – 225L/Min @ 5.0 Bar

The NT Cloke triple variable speed booster set is designed to provide reliable, constant water pressure in buildings where the incoming mains supply is insufficient or demand varies throughout the day.

Delivering up to 225 litres per minute at 5.0 bar, this system is well suited to larger domestic properties and light commercial environments where multiple outlets are in use at the same time.

Each unit is equipped with variable speed inverter control, allowing the pumps to automatically adjust output based on demand. This ensures consistent pressure, improved energy efficiency, and reduced wear on system components over time.

Supplied as a complete packaged system, the booster set includes pumps, pressure vessels, and control components, all pre-configured and tested prior to dispatch for straightforward installation.

The system also includes automatic shutdown and restart protection, helping to safeguard the pumps in the event of water supply interruption.
