TC Duct High Limits – Used in a Material Dryer

When drying any material in an air stream you want to make sure everything is flowing. One of our manufacturers utilizes a TC High Limit Temperature control to make sure everything is on the move. An example they used was if the grain they are drying builds up and blocks the flow the temperature in the shaft increases rapidly. By presetting the TC they can insert it in multiple spots along the dryer to keep a check on the system. If the TC senses the rapid increase in temperature beyond the set point it automatically shuts the system down. The manual reset makes sure the system can’t be restarted until the blockage can be cleared. The adjustable models make changing temperatures as easy as loosening a screw and moving a dial. The tough metal case protects the switch in rough environments. This is a cost effective solution to a big problem. TC Duct High Limit Controls are used everyday in the world around us, we just have to do a little digging to find out where they are located.
