New pressurisation units released by Wilo

Wilo has announced the release of a new series of Pressurisation Units for closed heating and chilled water systems for use in commercial and industrial premises. 


They 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 (up to 90°C), LTHW and chilled water systems at a predetermined pressure by topping the system up with wholesome water via an AB air gap. 


Available in three different static head options, 35, 60 or 80 metres, these units are unique and amongst the first units of their type to be BACNet compatible making it possible to incorporate them within building management systems and to do so simply utilising a single cable interface.


In addition the display on the units is backlit, essential for many installations where they tend to get installed in the darkest recesses of the plant room. With two lines of text on the interface the units are simple to interrogate unlike those units which flag up feedback using codes that may need to be interpreted.A final benefit is the simple installation making these units ideal replacement units.


Wilo can help you to select  the correct pressurisation unit and expansion vessels for your system in accordance with BS7074 if you provide them with the following information: the static height of the building above the pressurisation unit in metres; the system content (litres) If unknown, provide the boiler power (Kw) which can then be used to estimate the system content; the flow and return temperatures; glycol content, percentage; and the final working pressure.
