Litzler invented and patented the End-Seal in 1995 and has continued to optimize the End-Seal to meet the changing needs of fiber producers. The original, patented Litzler design is the industry standard to which all others are compared. The Litzler G5 End-Seal eliminates the trapezoidal chamber effect and ensures that the entire length of the oxidation chamber is useful.
Why is an End-Seal required?
PAN oxidation produces toxic off-gassing that is hazardous. The G5 End-Seal is a highly effective dynamic seal that prevents the escape of toxic gasses to the atmosphere.
- The G5 End-Seal is based on aerodynamic venturi sealing to prevent vapors from escaping to the environment
- Positive sealing of the oven chamber
- Eliminates cold air infiltration into the process chamber and hot air egress coming into the plant
- Saves energy and reduces the overall exhaust for a smaller pollution control system
- G5 seal chamber reduces the size of the pollution control device up to 50% by eliminating excess exhaust
- G5 End-Seal effectively combats the chimney effect
- Maximizes the oven pass-length for increased throughput
- Improves side-to-side temperature uniformity
- All seal balancing is done externally and is accessible during fiber operation
- Independent seal chamber temperature control extends the length of the oven
- The heated G5 chamber minimizes the rate of tar formation at the slots
