CO detection is widely used for pre-warning in dryer installation safety systems. Uncontrolled process conditions can cause the product to coagulate and form lumps. These coagulated products are exposed to increased residence times, which can cause smoldering reactions. These smoldering reactions are a significant risk of fire and explosion. Over the years CO detection has proven itself as a reliable pre-warning system that shows a detectable increase in CO concentration due to smolder, more than 30 minutes before fire and explosion occurs
