The GM Treble PH2D Floor-Mounted Pressurisation Unit provides advanced features in a simple, robust and effective design.
Throughout a heating system, there is always potential for slight leaks to occur which gradually decrease system pressure leading to inefﬁcient or disabled heating. Once installed, the PH2D will automatically maintain optimal system pressure by constantly monitoring the system via a pressure transducer. When pressure drops below the entered set point, the unit will top up the system to its original cold ﬁll pressure thus restoring optimum operating conditions.
The PH2D has the added beneﬁt of a secondary standby pump. If one of the pumps were to fail, the digital controller will automatically switch to the standby pump, preventing any downtime. The failed pump can then be isolated and repaired / replaced at the earliest convenience.
The PH2D can be used for the following applications:-
