Professional Power Resistors from 3 Phase Power Systems

Since 1919 Danotherm Electric has designed and produced electro thermal components. Today their products includes traditional wirewound resistors, steel grid resistors, the most advanced insulated high pulse load aluminum housed resistors and steel tube resistors also for high voltage applications.

As a service to custumers Danotherm has developed THERMAL SIMULATION for all products intended for pulse load application. In this way Danotherm insures that the first choice of products is the right choice.

Very High PULSE LOAD compared to the average load

– Insulated resistors

-IP50 – IP65

– Can easily be mounted in compact constructions.

– The nominal load can be improved by forced air cooling or by mounting the resistors on a heat sink.

Power range 30 W – 6 kW Average Short time pulse load up to 300 kW/component Protection degree IP20/IP50/IP65

The traditional Brake Resistor Type.
This Resistor type has proven its reliability since the childhood of the Drive Technology.

Power Range from 100W to 5kW Average.

Pulse Load 10X PN at cycle 10S / 120S

There are two product lines; a traditional and one being UL listed

Aluminium Housed Heat Sink Resistors for steady state load Typr HSD/HSF and HSCC
Power Range: 40W – 200W

Ceramic Vitreous Enamelled Rheostats
Power Range 12W – 200W

Small Power Resistors
Axial and Radial lead Types

OEM Products based on our Power Resistors and optimized to Customers Specifications

Brake Resistors for medium and very large drives.
These resistors are naturalaircooledor forced air cooled.

Neutral Grounding Resistors for high voltage power networks.

Power Range from 5kW – XXMW

Protection Degree: IP00 – IP23

Ohmega Resistors are made by the same technology as infrared heating elements but are particulardesigned as braking resistors.
Can be air cooled as well as water- and oil cooled. The cooling media can be separated from the connection area making it possible to cool with polluted air.

Power Range 100W – 500kW (Water cooled)

VitreousWirewound Resistors
GRF/GFF:Power Range 17W – 300W
