Offering fan solutions for glass industry to meet your exact specifications.


There are 2 major categories in glass production, first is the glass containers which we see in our everyday life, for instance, glass bottles, glass tanks, glass bowls and other glass packaging containers. The second type is glass in sheet form that we used in modern building windows, tempered glass panels, sliding glass doors and all glass panels application.

Glass container manufacturing has already become one of the mature market businesses in the world. Yearly demand for glass containers and glass sheets has increased tremendously for the past decades, with approximately more than 50 million tonnes in the early 2000s. The main materials required to make the glass are sand, limestone and soda ash and these materials are readily available in many countries. A typical glass manufacturing plant would allocate space for batch house, hot end, glass furnace, forming, annealing, cold end, coating and packaging. The glass furnace normally operates continuously for minimum a month or longer and does not shut down daily as it handles hundreds of tonnes of molten glass in the glass manufacturing process. It will be costly, approximate more than tens of million dollars, to purchase furnaces and glass forming machines, thus, most of the glass productions are made for stock and keeping stock level according to short term planning 12 weeks up to 24 weeks planning. Since the production capacity could be monitored more precisely due to the continuous running of furnaces and automatic production machines, glass factories are sized to service the requirements of a city in general. A typical factory will produce 1–3 million containers a day to serve a developed country about 1 to 2 million people per day. Glass containers have reached a high level of consumer acceptance in the consumer market because the market views the glass packaging as high quality standard.

Glass sheet is made by floating molten glass on a bed of molten metal. The critical point in glass sheet production process control is to obtain uniform thickness and flatness of the glass sheet surface. Although the raw material of glass sheet is similar to that of glass container, manufacturers of glass sheet use different techniques and settings to anneal the glass sheet and obtain different level of hardness and strength of glass panels.

The glass making industry is required to use combustion air and cooling fans for the furnace area, exhaust fans, recovery systems, and recirculation fans during the process of forming the glass as well as mold cooling and air staging. Ferrari Ventilation provides a wide range of industrial fans and blowers for glass industry from the ventilation systems to heavy duty abrasion resistant fan solutions. The furnace is required to be equipped with proper cooling and combustion equipment whilst exhausts and fresh air are necessary to provide for the comfort of operators. For the dust control application, the heavy duty abrasion resistant fans are indispensable.

Recommended fan series are ART, VCM, FR, FA, FC, FE, FG, FI

he process of glass and steel production uses fans for tempering of glass. To complete a specific set of surface properties, it needs the high-temperature sheets of glass and metal to be exposed to high-velocity ambient air from glass blowers. During the part of a continuous operation, the air is typically filtered and directed onto the hot surface.

There are numerous steps of air jets which are directed at the quenched surface as long as the requisite surface temperature is accomplished. As the air is a poor heat transfer medium, the air-quench tempering blowers can considerably demand the air and horsepower. Therefore, the highest efficiency metal or glass tempering blowers are applied for this application.


nnealing of glass, commonly known as oven cooling, is a process of slowly cooling hot glass objects after the glass forming process, it helps to relieve residual internal stresses introduced during the glass manufacture stage. Those glass that has not been properly annealed, will retain thermal stresses caused by quenching, which indefinitely decrease the strength and reliability of the product.

Inadequately annealed glass is likely to shatter when subjected to relatively small temperature changes or to mechanical stress. Especially for smaller, simpler objects, annealing may be incidental to the process of manufacture. For more complex products, glass manufacturers commonly demand a special process of annealing in a temperature-controlled kiln because glass annealing is critical to its durability and reliability.


he glass mold temperature controller is necessary for the consistent molding. To supply the suitable cooling, the bottle machines use fans to circulate air over the molds.

This fastly disperses heat to attain the economical production and equally expand the temperature across the mold to ensure the product quality. To control the strenuous environmental conditions of the glass making industry requires the suitable and customized fans to meet that objective.
