Profile: Process Heating Co., Inc. concentrates on the use of low watt density, dry well style immersion heaters for heating all types of temperature sensitive products. Our drywell design allows the actual heating elements to be serviced without draining the heated tank/vessel. Our elements are supplied as direct immersion units for heating tanks, vats or reservoirs and built into pressure vessels to be used as circulation heaters & heat transfer systems. We provide hot oil heat transfer systems for automatic temperature control and pumping of transfer fluids.
