Quantum Q4
The Dutypoint Quantum Q4 is the latest in pumpless digital pressurisation technology for light commercial and residential buildings. It’s a slim, wall-mounted, pumpless top-up pressurisation unit, with a top-up flow rate of up to 14 l/min depending on the mains or boosted mains water pressure. It is designed to be connected directly to a building’s incoming water supply using the included flexible hose. It is there to fill and maintain the pressure of a heating or chilled water system without the need for a pump.
The unit comes with a user-friendly controller that displays all operating and error conditions comprehensibly and conveniently. It features extensive data storage for online and offline analysis, microprocessor control, and self-learning algorithms with a graphical display. It comes with MODBUS RTU and BACnet communication protocols as standard and has its key operating parameters password protected.
