Electrical design
All BUEL® thrusters are operated with 3-phase voltages between 220 V to 690 V @ 50 Hz or 60 Hz.

Protection class
All electric components of the BUEL® thrusters are located inside, for best protection against environmental influences. BUEL® thrusters are rated IP 65. Protection class IP 67 is possible as an option.

Operating modes
BUEL® Model G thrusters are designed for intermittent duty, independently from the required operating mode of the drive installed. There is no limitation of duty cycle. The motor is switched off after reaching the working pressure. In case the working pressure is not reached within 4 seconds, the motor is switched off internally.

Ambient temperature range
BUEL® thrusters are suitable for ambient temperatures between -30°C to +60°C. For deviating ambient temperatures, please contact us for support.

Protection against moisture
For applications in maritime or tropic environments, the optional use of a small heater to protect the motor windings from moisture is recommended.

Heater voltages can be:
>   110 to 120 V AC 50 Hz or 60 Hz
>   220 to 240 V AC 50 Hz or 60 Hz

Hydraulic media
BUEL® Model G thrusters are filled with a high performance synthetic oil, type PENTOSIN CHF 11S. This oil insures a trouble-free operation in the entire temperature range, indicated above.

Biodegradable oils can be used as an option.
