Our PH1L pressurisation unit is a simple, robust and reliable mechanical pressurisation unit designed with over 50 years of experience in sealed system equipment.
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 PH1L will automatically maintain optimal system pressure by detecting any loss of pressure via pressure switch. The unit will then top up the system to its original cold ﬁll pressure thus maintaining optimum performance and efficiency of the heating system. The continuously rated pump features a stainless steel body with a polymer impeller to help prevent pump seizures through infrequent operation, something common in other pressurisation units.
With its modular build, a PH1L unit can be tailored to the specific requirements of the system.
The PH1L can be used for the following applications:-
