Quantum Contract

The Quantum contract unit features a pressure switch controller to monitor and control pressure in heating systems.

Quantum Plus & Twin System

Quantum Plus pressurisation units feature the added advantage of twin pumps in a duty/standby configuration. In the unlikely event of a pump failure, the standby pump will continue to operate as normal.

The Quantum Twin System model is capable of managing 2 independent heating and chilled water systems. It features the same advanced feature set as the Quantum, with intelligent control and BMS integration.
