Unlike a chiller or a heat exchanger, the term cooler means different things to different people utilizing process cooling equipment. For some, the definition falls on the side of industrial refrigeration units used in product storage. Others define a cooler more generally: any product that plays a part in a cooling process.
Process Cooling & Equipment's January/ February product roundup includes coolers and cooling products to fit every definition. For more information on any of the coolers included in this roundup, contact
