When walking into any plastics processing plant, you’ll see a device called a temperature control unit, or TCU. A TCU is used to regulate the temperature of an injection molding, blow molding, extrusion, or other plastics process within a narrow range in order to ensure the quality and efficiency of that process. Unlike a chiller, which can only mechanically remove heat, a TCU can raise the temperature with internal heaters and cool it by directly exchanging it with lower temperature water through a heat exchanger.
A common type of TCU used in plastic injection molding facilities is Thermolator® brand units. These compact TCUs have been used since the 1950s, and each one incorporates a pump, a heater, and a cooling system to ensure the proper temperature is achieved and maintained in the injection mold. Thermolators from Conair don’t just heat or cool fluids, but instead, they regulate the temperature of processes to ensure the highest possible product quality and highest possible production rates.
