Soft Starter
Optional Equipment

In the direct start or star-delta start of electrical motors used in all reciprocating, screw compressors and other machines uses 6-7 times overload current. The electrical grid can be affected by this sudden load and this can lead to sudden voltage drops. In order to prevent these changes, a soft starter is used providing a soft start to the electrical motor and at the same time eliminating star-delta connections. With this optional feature, the lifespan of the electric motors is increased and the sudden changes in the network are prevented.
