Trebles - BoostBox Cat 5 Booster Set - 18L Tank - Twin Pump - 10 Bar. - 86m Head

Combining high pressure hydraulic performance with the operational resilience of twin pump duty/standby operation, the Trebles BoostBox 5236-260 is the most capable model in the BoostBox range. Designed for wall or floor mounting, this Category 5 compliant cold water booster set houses twin fixed speed pumps, an 18 Litre AB Air Gap break tank, digital controller, and solenoid fill arrangement within a compact enclosed aluminium unit.

Factory set to 8.0 Bar with a 1.0 Bar differential, this model delivers up to 86m Pmax, a maximum operating pressure of 60m, and maximum flow up to 17 L/min. The twin pumps alternate automatically to distribute duty hours and extend service life, with automatic standby changeover providing continuity of supply in the event of a pump fault. Solenoid fill, dry run and low water protection, error logging, password protection, mains isolator switch, and BMS-ready volt-free contacts are all included as standard.
