The BUEL® Model H is a family member of the DELLNER BUBENZER brand BUEL®. The BUEL® thrusters are used for almost all kinds of industrial applications. The thruster feeds active or passive hydraulic brakes and emergency brakes. It is also suitable for small-capacity hydraulic cylinders and has an operational pressure of up to 250 bar.
They are setting new industry standards for disk and drum brakes as well as wheel brakes.

Description
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. As an option, protection class IP 67 is possible.
Operating modes (BL 35-5 to BL 600-8): BUEL® thrusters are designed for intermittent duty, independently from the required operating mode of the drive installed. Any limitation of the duty cycle is not required. After reaching the end position (brake released) the motor is switching off. In case the end position is not reached within 4 seconds, the motor is switched off internally.
Ambient temperature range thrusters are suitable for ambient temperatures between -30°C to +60°C. For deviating ambient temperatures, please get in touch with us for support.
Protection against moisture: For applications 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 H thrusters are filled with high-performance synthetic oil, type Fuchs Titan CHF 11S. This oil ensures a trouble-free operation in the entire temperature range, as indicated above. Biodegradable oil is available as an option.
Installation positions: All thrusters are preferably operated vertically (piston rod on top). A deviation of +/- 30° from the vertical axis is permitted. A horizontal installation is possible as an option (please indicate with the order).
