History and Production of DANFOSS
The world first heard about the manufacturer DANFOSS in 1933, when Madsen Clausen founded a factory in Nordborg, Denmark. The industrial headquarters of the company is located in the same city where the company was established.
Main Areas of Activity
DANFOSS specializes in the production of engineering equipment that ensures energy consumption reduction in refrigeration and heating systems. This is achieved through the use of special electric motors that operate at various power levels.
The main products and lines of this manufacturer include:
- Thermal automation (individual heating points, measuring equipment, system control devices, thermostats, fittings for water supply systems);
- Power electronics (frequency converters up to 1400 kW of the VLT brand, decentralized drives, soft starters up to 800 kW);
- Refrigeration equipment (compressors, water regulating valves, thermostats, sensors);
- Industrial automation;
- Heating cable systems;
- and others.
Frequency Converters
One of the largest areas of production is power electronics. Since 1968, DANFOSS has started producing frequency converters of the VLT brand, which are market leaders not only in Europe but also beyond its borders.
Converters can be universal, specialized, or industrial, depending on the application, equipment requirements, and load.
The main purpose of using frequency converters is to control the rotational speed of an electric motor shaft and adjust the torque. This is achieved by changing the frequency of the alternating current. They also protect the electric motor and provide the ability to monitor the entire system, ensuring energy savings and uninterrupted operation of equipment.
Soft Starters
These devices are available in several series with different technical specifications and capabilities. Their areas of application include ventilation systems, pumping units, and smoke extraction equipment, among others.
By using soft starters, DANFOSS reduces starting currents, protects electric motors from overheating, extends the service life of equipment, and eliminates jolting or hydraulic shocks in mechanisms and pipes.
Devices of this type are capable of diagnosing system conditions, detecting failures and errors. They are remotely controlled and operate automatically. Compared to standard starting methods, the use of such devices saves time.
