Triple Variable Speed Booster Set – 150L/Min @ 5.25 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 150 litres per minute at 5.25 bar, this system is ideal for domestic and light commercial environments, particularly those with unvented cylinders, modern bathrooms, and high-resistance fittings.

Each unit features variable speed inverter control, allowing the pumps to automatically adjust output based on demand. This ensures consistent pressure, improved 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.

In the event of water supply interruption, the system includes automatic shutdown and restart functionality to protect the pumps and maintain long-term reliability.
