To save energy at a national level, Turkish government has implemented laws and regulations concerning energy saving, requiring companies to be more proactive efforts. At a dairy factory of Ak Gıda Sanayi ve Ticaret A.Ş. (Ak Gıda), Turkiye’s largest dairy company, the increased energy cost is a key factor that may jeopardize productivity and the company’s economics. Improving efficiency was the urgent task in order to reduce energy cost and reinvest in development to produce better dairy products.

The experienced specialists visited the client’s factory, assessed the usage and environmental conditions, provided consulting service for the efficiency improvement. In this factory, one of the main factors determining the energy consumption was the cooling system that required to maintain low temperatures used for sterilization process. Based on the specialist’s advice and mutual discussion, the client decided to replace several low-capacity ammonia screw chillers with a larger centrifugal chiller with higher efficiency manufactured by MHI Thermal Systems, and this chiller replacement contributed to reduced maintenance cost in addition to the electricity cost.</p> <div class="thumbnail-36031 wide-img al-center mb-32"> <div class="cta-modal-banner-item" id="image-src-item"> <div class="cta-modal-body width-m" id="image-src-body"> <div id="modalCloseButton-36031" class="cta-modalCloseButton"> <div class="button-inner"><span></span><span></span></div> </div> <img class = "cta-img-36031" src="/sites/default/files/assets/case-studies/reduction-of-energy-costs-by-60%25-with-energy-audit-and-chiller-system-revamping/energy_audits_cs_1.jpg" alt="Specialists conduct energy audit"> </div> </div> <img class = "img-src-cta p-36031" src="/sites/default/files/assets/case-studies/reduction-of-energy-costs-by-60%25-with-energy-audit-and-chiller-system-revamping/energy_audits_cs_1.jpg" alt=" Specialists conduct energy audit" /> </div> </div> </div> <div class="content-inner free-paragraph paragraph-img_h3_title_description mt-pc-80 mt-sp-64 mb-pc-40 mb-sp-32"> <div class="section-text-area width-s"> <div class="section-text-area width-s"> <h3 class="text-title mb-40 al-center">Replacement with high-efficiency centrifugal chiller in minimum downtime</h3> </div> <p class="text-wide mb-40" style="white-space: pre-line">After discussing ESCON’s audit report, our client decided to optimize the energy efficiency by revamping the chiller system including auxiliary equipment such as pumps, valves, and piping.
