Store utility costs have been on the rise consistently for the past decade, and in 2010 a client called upon Ken Welter, one of our Managers of Refrigeration and Design with more than 30 years of engineering experience, to design a system that would help reduce them. Complicating the project was the size of the store: at 65,000 square feet, it was 50% larger than the average retail grocery store.

Ken, with the assistance of a mechanical and electrical engineer, designed and implemented a Fuel Cell system (outside the normal scope for a refrigeration engineer) that provided 90% of the store’s electrical power requirements and 70% of its space and hot water heat through heat reclaim.

In addition, he was able to reduce refrigerant charge by 75% and significantly cut piping by mounting miniature compressors and condensers on the low temp cases. Instead of conveying refrigerant all the way through the building to a central condenser on the roof, the system was consolidated to just the refrigerated area of the store, cutting the potential for refrigerant leaks.
