Why treated water for technical purposes?

Water circuits need demineralised water

Water-filled systems, such as heating and cooling systems, power plants, industrial installations and ship engines, place high demands on water quality. Tap water contains minerals, salts and gases that lead to deposits of sludge, limescale and rust in water-filled systems. Tap water must be filtered until it is suitable for the desired technological application. In terms of its chemical and physical properties, technical water must comply with the technical standards established by manufacturers, engineers and professional associations.

The main benefits of demineralised water

• greater energy efficiency
• reduced maintenance costs
• allows for guarantee claims and consumer protection

The capacity of the ion exchange resin depends on the water hardness. For capacity values see the tables below, or calculate the value using the capacity figure of the resin quantity.
The PUROTAP® compenso 2 resin filling has a capacity of 4500 l at 1 °fH, or 2500 l at 1 °dH.
For the German hardness scale, use the figure 2500 and divide it by the water hardness in °dH. For the French hardness scale, use the figure 4500 and divide it by the water hardness in °fH. The result indicates the capacity of the resin in litres of water.
Example: At a water hardness of e.g. 12.5 °dH the capacity of the resin is exactly 200 l demineralised water.
