Pressurisation units for heating and chilled water systems
Wilo pressurisation units are available in four ranges to suit every installation. From open pack base mounted, comfort wall and floor mounted and twin systems able to control both heating and chilled systems. Each range has one and two pump models available with a selection of pumps to suit a range of static requirements. Wilo pressurisation units are designed to keep sealed MTHW*, LTHW and chilled water systems at a predetermined pressure by topping the system up with wholesome water via an AB air gap. 1 or 2 pumps are controlled by the Wilo comfort controller.
Comfort Controller The comfort controller works on closed loop pressure control via an analogue pressure transducer and an electronic micro processor ensuring accurate measurement and feedback of system condition. The control philosophy allows the duty pump to run, ensuring that the cold fill pressure (CF) measured in bar is constantly met. 2 pump models will rotate the duty automatically between both pumps ensuring even wear; if the duty pump fails the standby pump will start automatically. To ensure efficient operation of the sealed system the comfort controller also monitors the number of pump starts and changes in pressure providing excess start or system leak alarms if operating outside of the standard parameters. The controller has a two tier security access with view mode allowing access to the hand / off / auto function and then to view all other parameters only. The user mode requires a password for access to parameters such as cold fill pressure, high pressure, low pressure and excess starts alarms.
System Fill The open pack and comfort range, with exception of wall mount unit, can fill the system without the need for a quick fill loop. The comfort controller has a system fill command that will enable the pump to run for a maximum of 24 hours or until the CF pressure has been met without activating any alarms.
