Wire Preheating Systems
In-Process Wire Heating

Preheaters from Beta LaserMike provide uniform, in-process wire heating to eliminate insulation voids in primary cables. When a wire is preheated for only fractions of a second by a low frequency (50/60 Hz) heat cycle, the heat is unevenly applied to the wire, resulting in hot and cold spots. When high frequency preheating is used, more heat cycles are applied to the wire, ensuring more consistent heating all along the length of the wire. For this reason, all Beta LaserMike Preheaters use high frequency heating. Beta LaserMike offers a full range of models to meet your unique wire preheating needs.

  • Industry leading safety features.

    Wire break detection, current overload sensors, and a concealed wire path behind the electrically locked door provide peace-of-mind safety to your equipment, process, and personnel.
