Ion ScaleBuster Water Conditioning - Plastic Industry Cooling System 2 - Case Study
RD Plastics is a leading manufacturer of injection molding plastic components for the automotive industry.
WATER SYSTEM CHALLENGES
Closed circuit cooling water is used for the cooling the tools. As makeup water for the cooling circuit (water-air chillers), RD uses a blend of city water and storm/rain water. Due to the jellification in the chillers, 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 over 25,000 gallon (100m3) of fresh water (and a lot of salt) every week.
