Introduces ERH2-C3 for Tempering Low-E Glass
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.
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.
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
Convection heating system, which allows for variation of heat transfer
throughout the heating cycle to match the needs of the low-E glass
