Heat Transfer Screw Processors
During the processing of many bulk materials, there is a requirement to cool, heat, or maintain a specific product temperature while conveying the product. The desired temperature fluctuations must be calculated and engineered into the system to accomplish the preferred objectives. KWS Heat Transfer Screw Processors are the perfect solution for these applications.

Common Applications for Thermal Processors
- Cooling fly ash from boilers at coal-fired power plants
- Heating lime for asphalt shingle operations
- Maintaining a specific temperature for food products
- Cooling drill cuttings from a rotary dryer
KWS Heat Transfer Screw Processors indirectly transfer heat to or from bulk materials by introducing a heat transfer medium such as cool water, hot oil or steam through a special trough jacket and/or center pipe and hollow flights. Cooling or heating a bulk material to a desired exit temperature is accomplished by the surface area of the screw processor and designing the system flow to match the heat load requirements of the application.
KWS Heat Transfer Screw Processors are very cost-effective when compared to other methods of heat transfer. KWS designs and manufactures Heat Transfer Screw Processors to meet the needs of many industries, such as Chemical, Minerals Processing, Food, Power and Wastewater Treatment.
