Automatic refill units

Masterflow Pressurisation Packages protect town water supply from cross contamination and accommodate the change in water volume from system expansion and minor water losses.

Economical, reliable and convenient

Masterflow MICROFILL Pressurisation Units are generally supplied within a wall mount enclosure, containing pressure pump/s, break tank, regulator valve, pressure switches and associated wiring.

Designed for closed-loop circuits these units provide backflow prevention in accordance with AS3500 National Plumbing and Drainage regulations, and ensure automatic refilling of the system.

WE CAN HELP YOU CHOOSE THE RIGHT Automatic refill units FOR YOUR PROJECT

Masterflow’s pressurisation units do not require regular statutory maintenance checks thus eliminating ongoing expenses. The physical air gap of the break tank eliminates completely the possibility of back flow to the water supply system.

This is often the reason engineers and facility managers choose the Microfill system, due to the safety of these systems against double check valve arrangements. Furthermore, each individual system is factory tested and signed off by qualified personnel.

Case Study

Royal Australian College of Physicians

This charming heritage building nestled between more modern 1970s style structures and stands as a monument to Sydney early Macquarie era days. Originally used as a newspaper printing facility, it is now the home to RACP. This is where overseas medical professionals come to validate their overseas training and gain Australian recognition. In July 2016 an upgrade to their existing chilled water system was approved, and the work finished in July 2018.

The design criteria is necessary to ensure the correct model refill unit is selected for the application. A schematic is always useful, but not imperative. Other aspects of the system to consider include:

  • Max system pressure
  • Static pressure
  • Installation location and number of levels above.
  • Max temperature
  • Min temperature

There are various models within Masterflows’ Automatic Refill unit range, depending on the static pressures and critical nature of the circuit. These are:-

  1. Standard – 300kpa operating pressure
  2. High pressure, type 1 – 550kpa operating pressure.
  3. High pressure, type 2 – 850kpa operating pressure.
  4. Extra High pressure, type 3 – 1600kpa+ operating pressure. Floor mount

Frequently asked Questions

Yes they can. However, the surface finish is powder coated and so over time they will fade. If tanks are to be in salt spray environment, a special paint finish or stainless version will be required at extra cost. Remember to request this with the sales staff when obtaining pricing.

Where the Refill Unit will be located within the building is important and must be communicated to Masterflow Sales Staff to make a suitable selection. By location we mean basement, on roof plant room and so on. The position within the system of the Refill Unit will always be in the return side of the circuit.
The name Pressurisation is common in the UK and other parts of Europe. Because these devices are refilling, they are in effect maintaining the pressure in the circuit (pressurising) and hence the name pressurisation. So yes, they are the same thing!
The standard range of Automatic Refill Units are suitable for system pressures up to 550kpa. Above this special high pressure versions can be custom made. There is no limit to the pressures we can cater for.
