  • Potable water entering the skid is filtered to 5 μm and UV sterilised before being fed to the pump.
  • The pump boosts the pressure to 45 bar at a maximum rate of 60 litre/min, the actual pumped flow will depend on demand and will be controlled by the variable speed drive.
  • After the pump, the water is split into hot and cold streams as well as to a 12 litre (4 litres x 3) accumulator assembly.
  • The hot water stream is heated and controlled to 55°C in the high-pressure heater tank and then fed in to the hot water ring main.
  • The system is designed in such a way as to create a thermosyphon effect in the hot water ring main, where cooler hot water returns to the skid for reheating which will keep the ring main warm at all times.
  • The cold water is piped directly in to the cold water ring main.
