HKR GMBH

Our fully automated winding centres for fine and self-bonding wire make us the perfect partner for any tasks you require. Our coils are tinned with lead-free coatings (RoHS). To manufacture self-supporting coils, we use self-bonding wire. During winding, the surface of the wire is bonded using hot air. To ensure the coil connections can be soldered, they are then stripped of insulating enamel using a fully automated milling process. PRUFREX is able to make air core coils with wire thicknesses from 0.045 to 1.6 millimetres.

Our fully automated winding centres for fine and self-bonding wire make us the perfect partner for any tasks you require. Our coils are tinned with lead-free coatings (RoHS). We can wind onto any desired coil form using many different press-in ferrite and metallic cores. Multiple tap coils are also possible. Pins are automatically applied to the coil connections during the winding process, with wire drawing electrically controlled. Our winding machines handle single-chamber and multi-chamber coils with wire thicknesses from 0.045 to 0.71 millimetres.

The DRAGON Domestic Vertical Wind Turbine is an efficient and reliable renewable energy solution designed for domestic use. With a turbine power of 500W and a voltage of 48DC, it harnesses the power of wind to generate electricity effectively. What sets it apart is its ability to start producing electricity at low wind speeds, with a starting wind speed of just 1.2 m/s. This means that even in gentle breezes, it can begin generating usable energy. Built with durability in mind, the DRAGON Turbine ensures reliable performance over an extended period. Its lightweight design facilitates easy installation and maintenance, making it accessible for homeowners. Moreover, its modern and sleek aesthetic seamlessly integrates into residential settings, enhancing the visual appeal of your property. By utilizing wind power, this vertical turbine offers an environmentally friendly alternative to traditional energy sources.

Preparatory, finishing and other required operations are carried out using bench drills and grinders and other small tools. For example, we provide winding of electric motor components. Polishing and polishing of workpieces. soldering of printed circuit boards, soldering, welding
