Caliper

Induction heating calender actuators
New and unique solution for achieving high efficiency and fast response on on calender temperature control.
Using the proven and well known inductive heating principle, utilising 'state of the art' semi-conductor technology.
Minimal energy losses and stray radiation thanks to special field concentration technique and having the work coils direct on the generators.
Compact design, allows for easy installation and servicing.
Precise control - due to narrow zone widths, as low as 50 mm/zone
Independent actuator control system available, or can be controlled from the existing QCS/DCS system
Automatic control provides typical 2-sigma spread reduction of more than 80%
