Resistors : Load banks
We have a product range from 50W to 200K W, standard or custom-made to customer specifications, including low inductance resistors, high voltage cut-off, high operating voltage, suitable for high energy pulses and designs for natural cooling or forced ventilation. Our resistors can be supplied from IP00 to IP54 and in special versions (with special insulation, non-inductive, special terminals or cables and thermal switch.
Boxed
For applications such as variable speed and frequency drives, cranes, industrial automation, motor control, dynamic braking, renewable energies (such as wind and solar) and both loading and unloading, these boxed resistors consist of a tubular helical resistor. That is, it is a ceramic tube with a high degree of thermal dissipation and mechanical strength inside a galvanized sheet metal box IP20 and properly perforated for proper ventilation. This type of boxed resistors is manufactured according to the characteristics requested by the customer, customizing the boxed resistor with a cemented coiled tubular resistor or helical coiled tubular resistor; a high degree…

Braking resistors
Braking resistors are intended to dissipate the energy generated by a motor during deceleration, preventing damage to the drive due to overvoltage and ensuring that it stops safely. TORIVAC is a manufacturer of different types of dynamic braking resistors, which offer an economical and small size solution for braking control by absorbing and dissipating energy efficiently and effectively. A braking resistor helps to slow down or stop a motor by dissipating the excess voltage generated by the decelerating motor.

Cemented
Our high power cemented resistors are manufactured from high quality resistive alloy wire. The ohmic value varies little with the temperature rise of the element. These are wound resistors composed of a resistive element wound on a ceramic tubular core used as a support and coated with a resin to ensure high dissipation capacity and excellent resistance to thermal shock and overload. It is a low inductance open element that allows very low ohmic values.

Grounding resistors
Neutral grounding resistors are especially recommended for the protection of power transformers and generators in case of ground faults in medium and low voltage electrical distribution networks. Our custom-made grounding resistors, equipped with a current transformer, offer a high thermal capacity to absorb large currents. Our resistors can also integrate all types of accessories (switches, contactors, control elements, terminal boxes, etc.).
