Circulating chilled water or glycol systems are very common in many industries. The chillers often have internal temperature probes that result in unnecessary circulating pump running costs. Moving the temperature probe to another part of the system can be a cost-effective energy saving opportunity.
Read the case study below to find out how Millennium Plastics Ltd changed their chiller control system and reduced annual electricity use by 7,100kWh.
LinkPlas Ltd is a manufacturer of PET containers based in Albany. The company requires a reliable supply of cooling water to cool its injection moulding machine hydraulic-systems.
Their cooling tower is sized to achieve the required cooling duty on the hottest days of the year, and their fan ran continuously at a fixed speed, so much of the time the amount of water cooling far exceeded what was required.
