What is “Physical Conditioning”?

“Physical Water Conditioner” is an umbrella term use to describe a group of products which can reduce, prevent or remove the formation of hard (lime) scale in areas supplied with hard water. They are generally small devices which are simple to install and are plumbed in to the water pipe close to the point of entry into the property. The conditioners currently available are the result of decades of product development.

The main reason for the installation of a physical water conditioner, is for scale reduction and/or scale removal – hence the alternative description of the products as “scale reducers”.

For over seventy years Culligan has led the way in water treatment technology supplying our customers with safe high quality water for drinking, cooking, cleaning, bathing and manufacturing, from the smallest to the largest applications, commercial and industrial market sectors.

Our water conditioners can be installed in isolated areas and either vertically or horizontally, treating high flow rates with no dramatic effect on pressure losses.

The Clearscale range requires no electrical connections or power requirements ensuring a cost saving to our customers. The units will not require commissioning or any maintenance plan.

They have been designed with no moving mechanical parts, meaning that they aren’t subject to breaking down and our 10 year guarantee means our users can expect many years of conditioning in their systems.

As there is no power, moving parts or external influences, there is nothing to cause the unit to fail. This means that the unit does not need to be connected to a BMS system. There is no danger of it going offline. So long as the water is flowing, the unit is working.
