FdueG has gained extensive experience in the design and manufacture of dry type iron core reactors, with natural air, forced air or cooling water.
These products are designed for applications in every industrial sector and  are suitable for special environments or particular load conditions.
FdueG provides different types of iron core reactors:

They compensate the capacitive current present on the network to which they are connected and are used for the stabilization of the voltage.
Shunt reactors can be designed with many tap positions to be used as a balancing of dynamic loads in industrial installations.

They balance and level output current in systems with AC / DC converters connected in parallel. They allow to improve the balance of the system by increasing the performance of the converter group.

They reduce or block the harmonics in AC networks. Filter reactors are often coupled with capacitors, they create a tuned circuit with the system to filter the harmonic currents multiple of the fundamental one’s generated by components of power electronics, generators, etc..
This category represents one of the most common use of reactors because they find applications in a large variety of industrial sectors.

When positioned upstream before AC / DC converters, they are called "line reactors": they smooth the harmonics of current and they limit sudden variations of voltage and current in the power supply line.
When located downstream of the converter, they are called "output reactors" and smooth out voltage variations and surges; they also reduce noise due to electronic switching.
The use of appropriately-sized reactors improves performance and reduces wear of the system components.

They reduce the harmonic currents and transient overcurrents (ripple) in DC systems.  Smoothing reactors are dimensioned for the harmonic content expressed in amplitude and frequency of the superimposed current on the continuous rated. The correct design of smoothing reactors allow to reduce losses and improve system performance.

They are used to reproduce working conditions of the equipment being tested. They are designed in accordance with the needs of customers for applications such as testing of switches or capacitors, limitation of the current, power factor correction or artificial loads creation. Test lab reactors usually present wide tapping, combinations of connection, intermittent load or high current.

They connect the neutral of a system with the earth to limit the current in case of a fault between phase and earth. Correctly designed for the plant they reduce or reset the currents and consequently losses, protecting other components of the system and staff.

They limit the inrush current of motors required during the starting phase. Motor starting reactors are inserted on the power line only during the starting phase, they allow to reduce the inrush currents of the rated current by 5/8 times to the ratio request by the customer, usually down to 2.5-3 times the rated current.
