The closed loop system is filled using local domestic water which has been run through the Puropal Complete. In doing so the water is demineralized, meeting fill water specifications of glycol and boiler manufacturers. It is also convenient to demineralize an existing “water only” system by circulating the system water through the Puropal Complete demineralizer. Not for drinking water.

Puropal Complete is pressure tested to 87 psi (600 kPa) and is therefore suitable for making a permanent connection between the local domestic water supply and the closed loop heating or cooling system.

The capacity of the ion exchange resin depends on the water hardness. The capacity for each Puropal Complete can be read off the graphs below. Example: With a hardness of 11.7 gpg (200 ppm), Puropal Complete 2 provides 53 gal (200 l) of completely demineralized water.

  • Demineralized water meets the strict quality requirements from boiler and glycol manufacturers
  • Removes all the aggressive salts such as chlorides, sulphates, and nitrates which specifically attack metals like stainless steel, copper, and aluminum
  • Removes scale producing ions like calcium and magnesium that damage components and block heat transfer
  • Lowers electrical conductivity, which reduces corrosion
  • Includes conductivity and flow meter
  • Includes ball valves and air vent
  • Easy to install and use
