Lime or other salts are found in almost every water source in their dissolved forms. In common language limescale is
responsible for hard water.
Depending on the amount of lime/calcium carbonate, the dissolved carbonic acid and the temperature of the water, the
minerals precipitate and start to crystallize. In other words it deposits on surface areas of your oil cooler,
heat exchanger, water chiller etc...
This inevitable process DOES cause substantial problems for technical applications.
The TDS (Total Dissolved Solids) deposits get deposited onto the heat transfer surface of the equipment through
precipitation, reducing heat transfer efficiency in water cooled/heated machinery and lowers the efficiency of the
heating installation/cooling system quite significantly.
Actually 1mm of scale encrustation reduces heat transfer efficiency by up to 30%.
If limescale deposits are left to accumulate, water flow is restricted and piping, water channels and water jackets become
plugged. Ultimately, ignoring scale depositions can lead to the destruction and possible failure of equipment.
In addition to loss of efficiency, process contamination can occur. Increasing pressure losses and decreasing flow
rates are other symptoms associated with limescale build-up.

Huge financial losses to industries are a result of breakdowns, unplanned shutdowns, process contamination,
high product reject rate, expensive parts replacements etc.
ScaleAwayTM descalers are specifically formulated to remove scale from the
water end of all machinery. These proprietary formulae are non-corrosive on construction metals and have
corrosion inhibitors specific to metal type being descaled.
