Do you have a new project or worried about the design and set up of an existing pressurisation installation?

Working to EN12828 & BS6644 we can assist with full design & calculations either for New installations or for replacement units. We can also help identify “Neutral Point”, a key location on any heating or Chilled Water circuit.

We will always provide copies of our calculations for your records and advise on the following key design elements;

  • Expansion Vessel sizing.
  • System specific vessel pre-charge pressure.
  • Initial “Cold Fill” Pressure.
  • Pump start / Refill set point.
  • Max working pressure.
  • Safety Valve lift pressure (based on Neutral Point Calcs)
  • Expansion Pipe sizing.
  • Identification of Neutral point.
  • High/Low pressure alarm set points.
  • High/Low pressure system interlock set points.

This is a specialist trade and can cost you dearly if you get it wrong.
