DGTH is a leading supplier of zinc die-casting components for the automotive industry.


Cooling tower water is used for the cooling of the tools. As makeup water for the cooling tower circuit, DGTH uses a blend of city water with approx. 14° carbonate hardness and rain water. Due to the jellification in the cooling tower, the hardness concentration resulted in a diameter decrease in the cooling ducts of the tools. This issue was countered by a partial softening to approximately 10°dH and coping with the remaining problems. The softening system required regular regeneration with approximately 2m3 fresh water and salts every 3 to 4 weeks.


In May 2003 DGTH installed an ION ScaleBuster SB80-16E for a flow of 40 m3/h (175 gpm) at the discharge of the cooling tower pump and decommissioned the softening system.


The solution resulted in the effect of lime-free tool cooling ducts and the discharge locations of the re-circulating water (which previously required regular de-scaling) was free of scale and maintenance free. DGTH estimates that including the saved salts, the ION ScaleBuster will be amortized after less than 2 years.


The patented ScaleBuster technology completely replaces traditional chemical treatment; providing control of scale and corrosion in various water process systems to create an exceptionally clean system. This dramatically reduces energy and water consumption, while reducing or, in certain cases, eliminating toxic water discharge to the environment.
