In recent years, the lack of replacement actuators for larger diesel engines and, in some cases, turbines has been a growing problem for shipowners and land-based facilities. Qtagg has launched new actuator units to replace the installed base of obsolete and unsupported models that have reached end of life.
With two marine-approved replacement actuators now available—the ASAC 120 and ASAC 420 models—owners and operators can keep their existing large diesel engines in operation for longer, extending their lifetime by years or decades. The actuators come with different kits to facilitate easy replacement of the old models during service upgrades, with commissioning in just one or two days per engine.
The high-performance actuators are designed for demanding engine-room and land-based environments with an ambient temperature up to 85°C. The motor in the actuators is brushless and the gear is life-time lubricated, making the actuators totally maintenance and service-free.
Their compact design simplifies retrofit installation, ensuring they can fit in the same space as any previous actuator. The dimensions and required cabling are compatible with the older Woodward and Heinzmann actuators, as well as actuators from ABB, Wärtsilä, Kongsberg and Nabco/Nabtesco.
