The initial situation:
fighting limescale with chemicals

Water is a cheap coolant, but: minerals are trapped in the circulation and lead to the formation of limescale throughout the system. This has a detrimental impact on thermal conductivity and cooling performance suffers. In turn this leads to higher energy input and the use of chemicals.

The optimum environmental solution: Win-win – no chemicals, lower energy consumption

The cwe system comprises of at least one flow housing and an electronic control unit. Pulses condition the cooling water as it flows through the housing, changing the crystallisation properties of the minerals that would otherwise form limescale.

cwe-Anlage in der Kältetechnik

No new limescale  but an ultrathin anti-corrosive layer is formed. In the case of legacy systems, the formation of further limescale deposits inside the pipes, heat exchangers etc.  is not only stopped but reversed – until almost complete removal of limescale after a few months.

Rückgang von Kalkablagerungen

The lime is now transported in the water in the form of microscopic crystals. The difference between unconditioned (left) and conditioned (right) water is easily visible with a light microscope.
