FdueG has gained extensive experience in the design and manufacture of dry type air 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 air core reactors:

They limit inrush current during the handling of condenser batteries on AC networks and, if there is a fault, they reduce short circuit current. During normal operation damping reactors reduce electric stress on insulating materials, preventing the condenser connections from being damaged.

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.

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.

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 lower the fault current of the plant to levels that are compatible with available control system and interruptions; therefore they make it possible to find cheapen solutions in plant design on to adapt existing plants to higher power without replacing all the circuit breakers.
Such reactors can work non-stop at normal current and impedance, but they exhibit high mechanical resistance in order to sustain efforts caused by high fault currents for a specified period of time.

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.
