Interlocks

Trapped key interlocks prevent access to live electrostatic precipitators and promote worker safety. The interlocks’ system forces workers to adhere to a systematic process each time internal access to a precipitator is required. Each step releases a key that permits activation of the next stage in the process, which disallows access to live precipitators.

Trapped key interlocks prevent access to live electrostatic precipitators and promote worker safety. The interlocks’ system forces workers to adhere to a systematic process each time internal access to a precipitator is required. Each step releases a key that permits activation of the next stage in the process, which disallows access to live precipitators. The device’s end-coding system facilitates faster delivery of interlocks, and the key transmits more torque to the lock than a standard pin tumbler key.
