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.
