Fives is a leading supplier in the global flat glass lehr market with longstanding experience in the industry for both flat and PV glass applications. We supply optimal annealing lehrs that ensure maximum performance. Every lehr is designed to consider the specific final product supply and to lower the total cost of ownership.
Continuous annealing
Our expertise includes a patented hot air continuous annealing process to give you total control over the residual stress, bow, dish and waviness of your flat glass.
Our annealing lehrs are designed to accurately control the cooling curve at every point of the glass ribbon – longitudinally and transversally. The key features include:
- Optimized heating to thickness and width requirements
- Up to seven transversal cooling zones for smoother control
- Improved lehr drive to fine tune lehr speed
- Accurate thermal balance calculation and proportional control system
PV GLASS
The industry is continuously investing in renewable energy sources. PV glass is a driver in renewable energy because it is a specialized glass that is used for solar panels. Through the photovoltaic process, it enables the conversion of light into electricity for an improved environmental footprint.
Fives has partnered with PV glass manufacturers for 20 years. Learn more about our outstanding installation of an annealing lehr for extra-large glass ribbons in China with a production capacity of over 300-metric tonnes per day.
With over 150 references, our expertise includes patented technologies to ensure maximum performance, improved quality and enhanced energy efficiency for greener manufacturing.
