The Terlotherm Delta range scraped surface heat exchanger from Terlet USA is USDA dairy-certified. One 75-square-foot Delta 700 unit can pasteurize 12,000 pounds per hour WPC using hot water. The dual-cylinder design combines maximum heat transfer for heating and cooling with a small footprint (16 square feet) and low maintenance costs (only one motor and one mechanical seal). The increased surface area allows a lower heating medium temperature, increasing plant up times between CIP cycles. U.S.-based pilot units are available for testing. An aseptic version is also available. 856-241-9970;
