Proton Products has extended it range of Induction Wire preheaters with heavy duty models for larger wire sections. With the ever increasing extrusion speeds, we observed a requirement for higher power and larger sections up to 50mm². We have developed a high power inverter and larger preheaters for the range 2.5 to 50mm². Both models are offered with either 25 or 34 KVA of Power. Machines feature high efficiency cores and hyperbolic controllers. Further these and all other PROTON Induction Wire Preheaters can be supplied with the inteliTHERM Spectral Radiation Wire temperature measuring system.
