In a custom application, Sterling Inc., New Berlin, Wis., helped a company that produces prepackaged meals maximize the cooling potential for its products. The company installed a SWK030 Winter Kooler with Auto-stage Pump and switchover package, a GPAC 70 (20-hp) portable chiller, 11 Royal Series water temperature control units (TCUs), and three Two-Zone Stack Racks.

According to Sterling, a central chiller system along with a Winter Kooler allows the customer to take advantage of "free" cooling during the winter months and provides more precise and accurate temperature control for the company’s process.
