At Hengli, we thrive on the power of the motor and motor accessories. Hengli's control panels and spare parts for marine use control three-phase induction motor’s direct starting and clockwise and counterclockwise rotation in any shipping machinery. With protection against short circuits, default phase, overloading and voltage loss, the marine control boxes help induction motors run stably and automatically in constant water pressure machines such as air compressors, ventilators, water pumps, central air-conditioners, port machinery, oil ships, oil platforms, boilers, and paper manufacturing machinery.
