There are different kinds of heaters and heating elements for different needs. Insulated VET-preheaters are suitable for the preheating of flat or round workpieces and are easy to use. The thermal insulation is part of the element. Fixing onto the workpiece is simple and fast using steel banding or clamping magnets.
VHV-heating mats are suitable for preheating, post-weld, heat treatments process heating, etc. VHV-heating elements are used for flat or round workpieces. VHVP-heating mats are about half the size of VHV-type heating mats and they are designed especially for Heatmasters’ inverters and Heatmasters’ thyristor-type power sources.
Heat treatment devices
The VLV-channel heater is designed for pre-and post-weld heating with normal heat treatment devices
VHY-stud heater is used for pre-and post-weld heating of studs and outlet tubes. The form of the VHY-stud heater enables attaching the heater near the weld. VHK-heating mat spreads like fingers and is suitable for use on cone-shaped workpieces. It is used typically on the welds of studs and outlet tubes etc.
The VLV-channel heater is designed for pre-and post-weld heating with normal heat treatment devices. It is used for the internal heating of tubes and other cylindrical workpieces as well as for heating temporary furnaces. The VLH-Channel heater is designed for pre-and post-weld heating using normal heat treatment devices. VLH is used primarily for preheating and temporary heat treatment furnaces but is also suitable for many other applications.
The VPE-chamber heater is designed for preheating pipes and tubes from the inside using normal heat treatment devices. There are two standard sizes, others are designed and produced according to the order. The maximum produced length is 7,0 m.
