Masterflow MICROFILL Pressurisation Units provide a dual purpose, both in back flow prevention and automatic refilling of the system, in accordance with AS3500 National Plumbing and Drainage regulations.
They are supplied as a complete package incorporating pump/s, break tank, expansion tank, pressure switch/pressure transducer and regulator valves all housed in a wall mounted cabinet. Designed for closed loop circuits to accommodate the expansion that results from increased water volume and also the refilling which is necessary when there are minor losses in the system. In the event of major system leaks the make up water is regulated which may limit the water damage.
The physical air gap of the break tank eliminates the possibility of back flow to the water supply system. The Masterflow MICROFILL units do not require regular statutory maintenance checks that other pressurisation systems require, thus eliminating ongoing expenses.
