WHDN Resistors

Fully welded, steel tank WHDN resistors are offered with tanks ranging in diameter from 100mm to 300mm.

A single resistor consists of steel elements with a diameter of 16mm, which are welded to a ring that is positioned within the tank. Different alloys can be used for the resistor elements, tank, and also the junction box. The resistor is positioned within the ring and sealed with a gasket. This design enables the resistor to be opened and the tank to be cleaned from the inside.

The electrical connection can be single, star/delta, or multiple. Inside the junction box, there are main terminals and auxiliary circuits, such as junction box heating, thermal protection circuits, and air bubble detection.

The resistor can be equipped with drainage, closing, or pressure relief valves. The standard mounting position is horizontal, but vertical mounting options are also possible (with height limitations).

Aluminum-cased WHBH resistors have high operating voltage. The active resistor wire has direct contact with the cooling fluid and must be cooled with demineralized water with or without glycol. Water input and output are located on the back side, opposite to the electrical connections.

Fully welded WHBH 16 resistor can have 3 or 6 steel tubes with a diameter of 16mm, welded to a steel tank. The water input and output can be on the top or on the back of the resistor. The connection can be open style with M6 threaded rods, IP00, or the resistor can be equipped with a junction box IP65/IP66.

Fully welded WHBH 32.4 resistor has mica-insulated elements. It has high operating voltage. Water output and input are located on the back side.

All fully welded resistors have undergone a pressure test of 12 psi according to EN 13445.

Resistor WHB 16.3 has an aluminum casing with seals. It has three tubular resistor elements and can be with or without a junction box. Water output and input are located on the back side.

HVB resistors are aluminum-cased resistors for applications with high energy surges. They have high operating voltage. The resistor is insulated and filled with sand (SiO) or magnesium oxide (MgO) to withstand energy surges.
