ESSTER (Evaporative Shallow Sump Thermal
Energy Recovery)

You want assurance that your product will not be over-pasteurized when a line stoppage occurs. ESSTER can prevent these types of problems.

Pronounced like your favorite aunt’s name, this unique feature is standard on pasteurizers, warmers, coolers and pouch coolers from Pro Engineering. ESSTER stands for Evaporative Shallow Sump Thermal Energy Recovery. The ESSTER system divides the machine into zones and cycles water from the sump in the zones where the temperature is cooler to the spray nozzles in those zones where the water temperature is rising too high. This process keeps your product from being over-heated.
