Our generators
The right power, from 1,5 to 200 kW
Fifteen generators: induction for steel and other metals, dielectric heating for wood, plastic and rubber. You choose the power for the job, and we build the set-up to your requirements.
Built for what you need to heat
Axes are hardened in five to ten seconds per cycle, band saw blades from 6 to 38 mm get their teeth hardened and the band straightened in the same line, and finger joints in wood are preheated at 7 kg a minute. Several of the set-ups are developed together with ALO Center AB.
Built on experience since 1956
Conny Küller began his career at Philips in 1956 and founded HF Teknik AB in 1992. Since 2010 the company is called HF Energy, with Tomas Küller as managing director, and today six employees develop, manufacture and service the generators, inductors and cooling showers in Norrtälje.
Keep your generators running
Service and spare parts for almost every existing HF-generator. Spare parts are delivered fast, some from our own production. In Norrtälje, Sweden, since 1992.
