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
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 5kW Average.
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
Vitreous Wirewound Resistors
GRF/GFF: Power Range 17W - 300W
Cemented Wirewound Resistors
ZRF/ZFF: Power Range 17W - 1000W
- Heat Sink
Aluminium Housed Heat Sink Resistors
for steady state load
Typr HSD/HSF and HSCC
Power Range: 40W - 200W
- Heating / Dehumidifying Resistors
Large surface aluminium housed resistor that disposes of heat without the use of additional heat sink
Ceramic Vitreous Enamelled Rheostats
Power Range 12W - 500W
Small Power Resistors
Axial and Radial lead Types
Power Range 3W - 20W
