Glasstech Introduces ERH2-C3™ Furnace
Based in Perrysburg, Ohio, Glasstech Inc. has introduced the ERH2-C3, a new system for tempering high-performance, low-E glass. According to information from the company, the system processes these products efficiently by utilizing hot air convection nozzles above and below the glass surface to heat both sides of the glass equally, translating into short cycle times and increased productivity compared to other systems.

The ERH2-C3 is capable of heating high-performance coated glass in 30 to 35 seconds/mm of thickness. The company says this takes up to 70 seconds/mm on purely radiant heaters.

“The primary challenge posed by low-E coatings is that they reflect much of the radiant energy striking the top of the glass during the heating process, which means added time is needed to reach temperatures at which glass can be tempered,” said Jim Schnabel, vice president of product development. “Convection-assisted heating enables Glasstech to achieve heating times for high-performance coatings similar to those attainable on uncoated glass.”
The new system features Glasstech’s patent-pending Time-Profiles Con-vection heating system, which allows for variation of heat transfer throughout the heating cycle to match the needs of the low-E glass being processed.

Polytronix Offers Polyvision™ Glass
Polytronix of Richardson, Texas, has introduced a new version of its Polyvision glass, also known as privacy glass or electrically switchable glass. The product is based on a patented technology called Polymer Dispersed Liquid Crystal by Kent State University.

Polyvision glass is designed to turn from milky white to transparent or vice versa at the flip of a switch. The company says it is ideal for interior applications such as conference rooms, executive offices, homes, bank teller windows, dividers in hospital intensive care areas and more.

According to the company, Polyvision has 5-percent or better transmission than other products in existence, reduced haze, wider viewing angles and looks more like regular glass when the power is on, yet still maintains image blocking power when the power is off.
