This fire protection system is available for retrofit on all Brown ovens and can also be retrofit to many other brands of single-station cut sheet machinery.
Located in the bottom ovens, the system incorporates Teflon® sheet curtains to help reduce the chance of oven damage or an accidental fire. During an emergency stop condition or power outage, the curtain automatically deploys between the sheet and the heating elements. The curtain decreases the chance of melted debris from coming in contact with the oven’s heating elements and protects them from damage.
In the event excessive sheet sag occurs during thermoforming, an independent safety sag eye automatically shuts the oven down, activates the curtain, and an air jet cools the sheet.
