UJa Haua lasigis For lour Future , Eriiga Buitrul Systems j Our CONTROLLABLE PITCH PROPELLERS have featured remote control systems for as long as we've been making them—over 26 years. With that much experience, we have the capability to develop flexible controls, designed to match opera- tor needs with hull and machinery characteristics. Built under ABS survey to ACC or ACCU requirements and backed by comprehensive vibrational and operational testing. Remote stations are drop-in panels: Pneumatic (1) or Electronic (2) to ease integration with ship control consoles. Control Trans- fer and Mode Selection Logic (3) is a fail safe system, with low voltage DC for back-up control. Propulsion Load Limit Logic (4) operates on a programmed power-RPM relationship. The pay- off with this system—improved fuel efficiency and less engine wear. Our patented Engine Load Sharing System (5) provides fuel rack equalization—which results in uniform load between two or more engines driving the same propeller. For FP or CP Propel- lers, retrofits or new construction, our service tested system compensates for calibration deviations between engine gover- nors throughout the full range of RPM and power. From hydrodynamic performance and CP propeller mechanical design to hydraulic amplification of remote controls, we have the experience to put you in control of your ship. Interested?
