A New Concept in Air Cooling
Cooling time can be reduced by up to 85.7%

A Revolutionary Heating and Cooling Roll without Oil or Water is Born.

The Air-Cooled Hybrid design allows for both "roll heating" and "roll cooling" in one roll without the use of water or oil.
The Air-Cooled Hybrid Rolls achieve excellent temperature ramp up time by induction heating while allowing for temperature reduction performance by utilizing blown or vacuumed air. The Air-Cooled Hybrid Roll is an excellent choice for high-variety, low-volume manufacturing where frequent temperature setting changes are required for grade changes, material changes or for cleaning the roll surface. Decreased time for temperature reduction equals faster startup time which allows for increased production.
The Air-Cooled Hybrid Rolls can also be designed for "balanced cooling" whereas the material makes contact with the roll at a higher temperature than the roll surface temperature. The cooling system will activate, maintaining the desired roll surface temperature. (bakenced cooling operation).
Above all, since neither water nor oil is used, there is no risk of failure due to water leakage or oil leakage.

Some of the benefits of the Air-Cooled Hybrid Rolls
