Castell Safety Electrostatic Precipitator Safety Interlock

Castell Electrostatic Precipitators by Castell Safety International Ltd normally referred as Castell Locks rank as one of the toughest environments for interlocks. The electrodes and collection plates in precipitators require maintenance to perform at optimum levels. With electrodes carrying a charge of more than 10,000 volts, stringent safety procedures are vital if operator access before isolation of the LV/HV transformer is to be prevented. 

Castell’s trapped key interlocks by Castell Safety International Ltd force workers to adhere to a step-by-step process every time internal access to a precipitator is needed. Each step releases a key which in turn permits activation of the next stage in the process. This system ensures that access to live precipitators is virtually impossible.

Typical light duty locking devices, such as pin tumblers, are prone to plugging and performing poorly in the high fly-ash environment within precipitators. Castell's durable brass or stainless lock mechanisms avoid ingress with a sealing key and a cap to minimize dirt or dust collecting.
