ModEvo Tension Brakes
**For intermittent duty and thermal ratings using 200 mm or 250 mm fan, consult the factory.
1 Minimum torques were calculated using a multiplier of 0.6 for LC times Standard.
2 LC - Low Coefficient based on 0.2 Coefficient of friction.
3 Standard based on 0.35 Coefficient of friction.
4 Max. speed is with standard brake disc. A high speed brake disc capable of 50% higher speed is
also available. Heat Capacity reduced by 10% when high speed disc is used.
5 Limit LC to 70% of heat capacity.
6 When selecting number of actuators, use a limit of 3.35 HP per actuator pair (2.5 kW per Actuator
pair) for duty w/o fan and 3.75 HP per Actuator pair (2.8 kW per Actuator pair) when fan cooled.
Note: Limit maximum operating temperatures of surfaces (rotor, friction pads, actuators, etc.) to
300°F or less. Temperatures above 300°F may cause damage and failure of components.
Failure to do so will void warranty.
ModEvo Model 450
* For single actuator operation torques for 450/1 are applicable.
