There are many companies and glassworks that could revolutionise their business by equipping themselves with their own glass tempering furnace. But they often decide not to take this step.
Why not? In most cases, this choice is due to a number of misconceptions that portray quenching furnaces as machines that are only suitable for large companies and that require an exorbitant investment, both in terms of purchase and daily use.
While this may have been true in the past, there are now many innovations in the world of glass tempering that are revolutionising the old concept of these furnaces.
1) A small glasswork does not have the space to install a tempering furnace > WRONG
This may have been true in the past, but today there are tempering furnaces designed to meet the needs of a small to medium sized glassworks.
They are characterised by a more compact design, which allows them to fit into the smallest of spaces. For example, Mazzaroppi’s TP Compact is only 15-19 metres long, so it can fit into a normal laboratory.
2) Installing a hardening furnace always requires expensive masonry work > WRONG
This too is a belief that has been overtaken by the latest innovations.
There are models, such as the TP Compact by Mazzaroppi, that have been designed to avoid the need for brickwork: this compact oven can even be installed in the middle of the glassworks workshop without the need for a supporting wall.
This makes the installation of the new machinery much easier and less costly, as no demolition or renovation work is required.
3) Installing a tempering furnace always requires upgrading your electrical system > WRONG
Fortunately, this is no longer the case: there are indeed solutions that can operate with a 200-kW cabin!
Some quenching furnaces equipped with energy efficiency technologies can reduce cabin costs by up to 70%.
4) Tempering furnace consumption is always high and therefore not a worthwhile investment > WRONG
It is true that glass tempering requires energy. But the latest innovations on the market make it possible to reduce the consumption of annealing furnaces in ways that were unthinkable until recently.
In fact, Mazzaroppi furnaces can save up to 70% of energy compared to other competing solutions, while maintaining very high glass tempering performance.
How can you save so much on your energy bills? Thanks to special technologies designed to optimise the energy efficiency of installations.
For example, the Start&Stop technology, which allows the ovens to be switched off every night so that they can be heated up very quickly the next morning. Or those based on multi-zone control systems, designed to heat only the areas occupied by the glass pane, without wasting energy where it is not required, but concentrating it where it is needed.
Therefore, by choosing a technologically advanced oven, it is possible to reduce energy consumption and pay back your initial investment more quickly.
5) Hardening furnaces depreciate quickly > WRONG
This is the fear that every entrepreneur has before making a major investment: “What if this machine is no longer worth anything in a short time?
Fortunately, this fear is unnecessary when it comes to heat-treatment furnaces, provided that you choose a model that offers certain guarantees. In fact, there are ovens that guarantee a residual value of up to 40% after 10 years of use: these are models that are made with top-quality materials, assembled with the greatest care, and meticulously tested before delivery.
By choosing such a model and, of course, not neglecting the maintenance of the system, you can ensure that the tempering furnace will have an average life of more than 30 years. And if the needs of your company or glassworks change, you can consider upgrading the furnace before considering the purchase of a new machine.
Innovation in the world of glass tempering is continuous and evolving, both in the direction of guaranteeing ever higher performance and in the direction of reducing consumption. This is why it is now possible to guarantee amazing energy performance by choosing the tempering furnace model that best suits your needs.
Mazzaroppi’s solutions are the most energy-efficient in the sector, thanks to the know-how acquired and deepened over decades of activity and to the continuous study of new technologies able to respond to the precise needs of companies.
