The DHI-44F WORKSHOP is a portable workshop induction heater with integrated water cooling for the induction heater and replaceable induction coil extenders.
The induction heater DHI-44F WORKSHOP has a number of innovative features for efficient and quick heating of bolts, nuts, shafts, bearings, sections, round steel, sheets, etc. The DHI-44F WORKSHOP has a fluent power control within a range of 10-100 % and a clear display showing presets and readings. Besides, it has a timer for simply selecting desired heating time, which combined with the controlled power mode enables relatively accurate and repeatable heating with controlled heat introduction, i.e., heating to a set temperature.

Technical data

Its high power capacity, small dimensions and light weight make the DHI-44F WORKSHOP ideal for workshops, car repair shops, general repairs, production, maintenance and industry. A significant advantage of the DHI-44F WORKSHOP compared to other heating methods is its safety, simplicity and high speed of heating and application, particularly compared to flame heating. Moreover, the use of the DHI-44F WORKSHOP induction heater is clean and environmentally friendly.


  • Higher security and better working conditions for operators. The operator is not exposed to open flame, hot gases and the risk of fire and explosion when using a flame.
  • Lower personnel training costs, lower wage costs. There is no need for regular staff to work on autogenous and PB burners.
  • Low operating costs and low cost of consumables. No gas costs. Low power consumption. Energy-efficient heating system.
