ProcessBarron SafeTBrake for fan systems

April 12, 2023 | By MRO Staff

ProcessBarron Canada SafeTBrake, a rotor-locking device provides an integrated lock on a fan.

SafeTBrake is a fully-assembled system consisting of dual air-applied calipers, air-ventilated discs, and a positive holding and lock. The brake system stops the rotor in under a minute. A pinning feature allows for physical lockout at fan.

SafeTBrake’s control package includes a manual on/off switch with permissive start and stop logic. The logic is set so that the brake will not engage if the motor is energized, and the motor cannot be energized if the calipers on the brake are engaged or locked.

“SafeTBrake protects equipment and saves unwanted downtime,” said Allen Ray, vice-president, ProcessBarron air handling group. “It locks the rotor to prevent it from free-wheeling backward and prevents damage to the bearings, couplings, and shaft when the motor is energized to start in the normal direction of rotation that is opposite to the free-wheeling rotation.”
