New Hudson Corporation introduced the HTC™ High Temperature Composite Ringed Roller to the float glass industry in 1991. By 2008, over 2000 HTC™ rollers are operating successfully in (73) float lines worldwide.
The HTC™ roller eliminates embedded cullet, which can become embedded in the surface of a covered roller. HTC rollers offer low thermal conductivity, a hard durable surface free of sulfate and dross deposits. HTC rollers eliminate “roll mark” problems in the cold end of the lehr.
The HTC™ roller is intended for use in lehr zones with circulating air. Typical lehr installation locations are CNUD RET, E and F1 zones and the Stein D zone.
