    Temperature Control Systems

    State-of-the-art temperature control system

    Heatmasters’ computerized state-of-the-art temperature control system for digital, easy, and accurate setting, controlling, monitoring, and documentation of the heat treatment process, even remotely.


    Minimized maintenance & downtime

    Thyristor based power output control minimizes maintenance work and decreases equipment downtime. Durable stainless steel covers give our units a sleek look and a long lifetime thanks to enhanced protection.


    Portable & lightweight

    Weighing half of the weight of traditional heat treatment units or less, our solutions are portable and easy to move around on-site.


    Distinct and clear user interface

    Signal lights ensure the status of the electrical network and heating resistors is crystal clear for the operator. Receive alarms and status reports to your phone.

    Preheating Units

    Our semi-automatic preheating units are suitable for the preheating of metal parts. These thyristor-controlled transformer type units have been designed with usability in mind: their simple and lightweight structure allows effortless mobility and efficient pre-heating at any location. These units are almost maintenance-free, ensuring cost-efficient and trouble-free heating operations.

    Induction Heating Units

    Heatmasters induction units are suitable for pre-heating, PWHT, shrink-fitting, and other heating applications. Of course, our induction units also utilize our integrated temperature control systems which ensure accurate and digitally documented heat-treatment processes.

    HM35 INU

    The HM35 INU is a multi-purpose unit, providing induction and resistance heating modes.

    Depending on the size of the workpiece, one or two heating units can be used. Induction coils or resistors are attached on both sides of the weld seam and when using only one heating unit, they are connected in series with a jumper cable.

    Thanks to the units’ portable and lightweight design, it is very useful to take on remote jobs as it is easy to handle and transport and can be easily powered anywhere with a single-phase 230V plug.

    Max Temperature: 750°C with Induction, 1050°C with Resistance Heating
