Castell Interlocks Safeguard Precipitators at APC Expo

Cocktail reception planned for Tuesday, July 14
Erlanger, Kentucky (July 1, 2009) – Castell will be exhibiting safety interlocking products at the Air Pollution Control (APC) Roundtable and Exposition, July 13-14, 2009 at the Woodlands Resort & Conference Center (Houston, TX).  Castell’s range of heavy-duty interlocks promotes worker safety by preventing access to live electrostatic precipitators.


Strict safety procedures are essential when working with electrostatic precipitators.  Failing to isolate the LV/HV transformer prior to maintenance operator access can expose workers to charges of over 50,000 volts.  Each time internal access to a precipitator is needed, workers must follow the step-by-step process imposed by Castell’s trapped key interlocks.  Each step releases a key which in turn permits activation of the next stage in the process, making access to live precipitators impossible.

The company’s new end-coding system facilitates faster, more accurate delivery of interlocks.  When an order is placed, locks can be quickly coded with the customer requested three-digit alphanumeric symbol. A large robust key with a neoprene seal or a stainless steel dust cap resists the plugging common in the high fly-ash environment of a precipitator guard against mechanical lock failures.  The key is capable of transmitting much more torque to the lock than a standard pin tumbler key for ease of operation. 

In addition to the company’s product exhibit at booth 37, Castell will be co-sponsoring a cocktail reception on Tuesday, July 14.  For more details on the event, jointly hosted with GE Energy’s Precipitator and Fabric Filter Divisions, CoorsTek and Stein Industries Inc., visit Castell’s booth at the show.
