CHILLER PLANT DESIGN FOR ELECTRONICS MANUFACTURING SITE

CONFIDENTIAL CLIENT


Printed circuit board manufacturing operation finds opportunity for 50% reduction in chiller plant energy consumption.

This leading global producer of printed circuit boards approached Enovity looking for opportunities to improve energy efficiency in their China operation and leverage available third-party financing. Understanding that in a production site, production always comes first, we focused on a component of energy use that doesn't vary with production: environment control.

Located within a large manufacturing campus, the facility had grown and expanded several times over its 20-year life span, and as the need for cooling grew, additional chillers were installed around the campus. Enovity performed an investment-grade energy assessment and identified an opportunity to consolidate all cooling needs for the printed circuit board production operation. By serving process and environmental cooling loads from a centralized 3,000-ton chilling plant, the facility was able to reduce distribution losses and upgrade to modern, high-efficiency chillers in the process.

The project located the new chillers in a new dedicated plant building, allowing the production operation to continue uninterrupted as the new plant was constructed and commissioned. Enovity provided design for the new plant building and associated cooling towers, air handling units, and automation systems.

With utility cost savings estimated on the order of $1.5 million per year, the $7-million project would pay back in approximately 5 years prior to any subsidies. Enovity qualified local equipment suppliers, contractors, and operators to deliver the new plant on a long-term Design-Build-Operate-Transfer basis, and also developed bi-lingual project contracting tools that addressed local requirements as well as the client's global procurement standards.
