GRIDEX U : For standard applications of long or short periods of operation, Gridex U resistors have a simple design which combines the thermal properties of Gridex G resistors with the technical characteristics of Gridex N and F resistors. Gridex U resistors consist of solid strips, in an extended diamond mesh shape with lateral stiffeners.
GRIDEX N & F:Gridex N and F resistors are designed to optimise the dissipation of heat caused by electrical current into the surrounding environment (i.e. non-adiabatic heating). Gridex N resistors are intended for natural ventilation, Gridex F resistors for forced ventilation.
The Gridex T resistors are made of woven resistive elements. The thread in one direction is not conductive whereas the thread in the other direction is resistive. This technology can provide high resistance values (reaching hundreds of ohms) and can be adapted to high voltage applications (both continuous and transient).
Vectrostar R :
The Vectrohm electrolytic starters are rheostats that always work in the liquid phase. This technology provides a continuous and progressive variation of resistance allowing motors to be started very gently.
