The Wärtsilä Unified Controls (UNIC) system takes care of all engine control and monitoring functions for both newly built engines and as a retrofit for older Wärtsilä engines. It is an embedded engine management system that handles start/stop management, engine safety, fuel management and speed/load control as well as charge air, cooling and combustion. The Wärtsilä UNIC engine control system is a durable, all-inclusive automation system specially designed for the harsh environments in which engines operate.
