Gridex U:
For standard applications, no matter whether the period of operation is short or long, Gridex U resistors combine the thermal capacity of Gridex G resistors and the technical characteristics of Gridex N and F resistors, although their design is less complicated. Gridex U resistors consist of solid strips, extra-extended diamond meshes and lateral stiffeners.

Gridex N & F:
When the current transit through the resistor provokes heat dissipation into the surrounding environment (non-adiabatic heating), the resistor must be designed to optimize heat exchanges. This is the case of Gridex N and F resistors. Gridex N resistors are intended for natural ventilation, Gridex F resistors for forced ventilation.

Gridex G:
When a resistor does not produce any significant heat exchange with the surrounding environment (adiabatic heating) when heated, it should have as great a mass as possible. This is the case of Gridex G resistors, which consist of steel sheetmetal elements cut into rectangles and mounted in staggered configuration.

Gridex T:
The Gridex T resistors are made of woven resistive elements. The chain warp thread wire is not conductive, the weft thread is resistive . This technology allows high resistance values (reaching hundreds of ohms) and can be adapted to high voltage application (continuous or transient)

Vectrostar R :
The Vectrohm electrolytic staters are rheostats that always work in the liquid phase. This technology provides a continuous and progressive variation of the Resistance value.Therefore, motors are started very softly using these resistors
