Benefits

Designed for Harsh Marine Environments

The CAR-H Series was developed specifically for installations exposed to strong vibration, humidity, and corrosive conditions. It is widely installed on main and auxiliary engine cooling systems aboard commercial vessels and offshore facilities.

High Torque Performance

Available in multiple actuator sizes, the CAR-H Series provides output torque from 60 Nm up to 2500 Nm, enabling operation of both small control valves and large butterfly or ball valves.

Maintenance-Free Self-Locking Gearbox

The precision-machined double worm gear is permanently lubricated and self-locking, preventing reverse movement caused by valve torque while minimizing maintenance requirements.

Reliable Motor Protection

Each actuator incorporates built-in thermal protection that disconnects the motor in case of overheating and automatically resets after cooling, improving operational safety and extending service life.

Flexible Automation

Depending on the selected model, the actuator supports simple ON/OFF operation, floating 3-point control, or fully modulating control with analog command and feedback signals for integration with PLC, DCS, and SCADA systems.
