Product Introduction

From 2007 to 2008, LandGlass started to research and develop gas heating tempering furnaces, focusing on gas combustion and glass heating. In 2009 LandGlass had discovered the optimal solution, in which the heat produced is suitable for The Forced Convection System. The result is a heating system based on a clear and efficient heat transfer.

After years of intensive research and development, in 2011 the Gas Heating Glass Tempering Furnace was formally launched to the market.

The Gas Heating Glass Tempering Furnace is a new type of tempering furnace that heats the glass sheets by burning CNG or

LPG. LandGlass designed and developed high efficiency burners to allow the gas to combust fully to create the heat that is then transferred to the glass surface. After the heating process, the hot glass sheets are tempered and cooled down.

Technical Features

1. The glass sheets are heated by burning gas, lowering dramatically the installed electrical power.

2. The furnace combines the efficient combustion technology and JetConvection Heating Technology. LandGlass proprietary burners guarantee a high speed, efficient combustion. The mature JetConvection Heating Technology ensures even and fast heating.

3. A clean heating environment inside the furnace is guaranteed by isolating the combustion system.

4. Interlock and ignition safety control systems are applied to ensure the complete safety of the system.

5. Glass that can be tempered includes: on-line and off-line Low-E glass, extra ultra clear glass, screen printed glass, pattern glass, tinted glass, clear glass, etc.
