DANOTHERM Products

high quality power resistors for the electronic-, the windpower- and the telecommunication industry.

DANOTHERM PRODUCTS

APPLICATIONS

Since 1919 Danotherm Electric has designed and produced electro thermal components. Today our programme includes traditional wirewound resistors, steel grid resistors, the most advanced insulated high pulse load alumininum 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.

ALPHA, Aluminum Housed Brake Resistors

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

Most of these resistors are recognized

SIGMA, Wirewound Brake Resistors

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

Power Range from 100W to 5kWAverage.
Pulse Load 10X PN at cycle 10S / 120S

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

TERA, Steel Grid Brake Resistors

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

Neutral Grounding Resistors for high voltage power networks.

Power Range from 5kW – XXMW

Protection Degree: IP00 – IP23

OHMEGA, Steel Tube Resistors

Ohmega Resistors are made by the same technology as infrared heating elements but are particular designed 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)

Ceramic Wirewound Resistors
