At the beginning of 2025, we completed a significant installation in Lombardy: a TP Compact oven for the family-run company Vetreria Aurora in Flero (BS).

We are pleased to share this experience as it demonstrates the potential of Mazzaroppi’s new patented Efficiency 5.0 software.

Who is Vetreria Aurora?

Founded and run by the Rossi family, Vetreria Aurora is a dynamic, quality-conscious company based in Brescia with 30 years’ experience in glass processing. They specialise in processing for the furniture, art and construction sectors. For them, installing our TP Compact is an important step towards more efficient and sustainable production.

The Mazzaroppi team was supported by our valuable local sales partner, Si.ste Trading, for the sale and installation of the furnace.

Why did Vetreria Aurora choose the TP Compact furnace?

The deciding factor in Vetreria Aurora’s purchase of the furnace was its low energy consumption.

Thanks to Mazzaroppi’s new patented Efficiency 5.0 software, we can actually keep peaks to a minimum.

Efficiency 5.0:

  • Drastically reduces the electrical installation required.
  • Allows you to select peak power depending on the production type.
  • Maximises consumption during all phases of the cycle.
  • Ensures even more intelligent and uniform heating of the plates.

All Mazzaroppi furnaces with Efficiency 5.0 improve productivity and hardening quality, with energy consumption up to 70% lower than competing products.

The Mazzaroppi solution

Vetreria Aurora has chosen the TP Compact oven, a 1600×3600 mm convection model that is perfect for handling all types of glass, including low-e. The TP Compact is a high performance, compact oven that can be easily installed and does not require a wall to lean against, thus eliminating the need for costly masonry work.

However, it is the oven’s technological heart that really sets this project apart: our new patented Efficiency 5.0 software.

Thanks to this innovation, we were able to guarantee the high performance typical of Mazzaroppi ovens while keeping the maximum installed power to a minimum at just 180 kW.

Despite the reduced power, Vetreria Aurora’s TP Compact can still temper glass from 4 to 19 mm thick.

There was also no need to install a dedicated electrical cabinet, which was advantageous for the company. Currently, Vetreria Aurora’s TP Compact is the only oven in Lombardy that operates without a dedicated electrical cabinet.

Glasstec 2024, held in Düsseldorf in October, was an opportunity for even the most sceptical to see the efficiency of Mazzaroppi furnaces in action: we brought a fully functional TP Compact furnace to our stand and demonstrated that it is possible to temper glass to perfection with just 180 KW of power!

Glass tempering has always been considered an extremely energy-intensive process. And it is precisely this belief that often leads glassworks and smaller companies not to have their own furnace, relying on external suppliers for tempering and thus losing out in terms of operational autonomy.

Fortunately, there is no need to equip yourself with a large electrical cabinet and spend a fortune on bills to temper glass at home. That is, if you choose a highly energy-efficient Mazzaroppi furnace.

The secret of energy-efficient glass tempering lies in technology: here are the innovative features and tricks that can reduce consumption without compromising the quality of the result.

1. Breakdown of total consumption

There is productive and non-productive consumption: both contribute to the total balance of energy required by the furnace for quenching.

In addition to what the machine consumes during production, any ‘idle’ consumption must also be taken into account. For example, if the furnace is left on at night or when it is not in use, all the energy required to keep it ready for quenching is wasted.

What can be done to avoid this type of consumption, which only represents a cost to the company?

Equipping a furnace that can start up and reach curing temperature very quickly reduces idle time. This is because the furnace can be easily switched off when it is no longer needed, without slowing down the work when it is restarted: thanks to the M Start&Stop ignition technology, Mazzaroppi furnaces can reach a temperature of 680° in just 30 minutes. This means that even small/medium-sized glassworks and companies that do not work night shifts can safely switch off the furnace at the end of the day and start it up again the next morning at full speed, avoiding leaving it on all the time and increasing the energy bill for wasted energy.

In order to absorb large and continuous temperature fluctuations, just-in-time ovens are built with low-absorption materials and low internal thermal mass.

2. Containing the energy peak

In order to contain the peak energy consumption of the oven, it is necessary to have advanced systems that allow very low dissipation and focus on increasing efficiency.

An oven equipped with software that guarantees this type of functionality can consume up to 70% less energy than less innovative solutions.

The deviation of the peak power, i.e. the maximum power required by the kiln, from the average power is reduced, while at the same time ensuring optimal temperature control of the kiln. As a result, 180 KW of power is sufficient to temper glass to perfection.

3. Optimising the heating of individual areas of the furnace

When tempering glass, one of the main causes of wasted energy is that portions of the furnace are also heated that are not occupied by the glass at that precise moment.

In order to optimise heat distribution, advanced software is required, which is able to recognise the exact portion of the furnace in which the glass is located and use the hot air only in that area, also adapting it to the percentage of occupied space.

On the contrary, management software, such as Mazzaroppi’s M Opticonvection, is designed to achieve superior hardening quality while reducing consumption to levels unimaginable with other solutions on the market.

They are based on complex algorithms that take into account many variables, with the ultimate aim of guaranteeing an incredibly favourable ratio between consumption and hardening quality.

In short, to reduce energy consumption and therefore the environmental and economic impact of tempering, it is necessary to heat the glass, not the furnace.

The lack of autonomy in production and the inability to handle more orders are among the reasons that slow down the growth of small and medium-sized glassworks.

The simplest solution to be more autonomous and serve more customers is certainly to purchase a glass tempering furnace and thus manage the processing in-house, without having to submit to the time frames and prices imposed by external suppliers.

It is not true that only large companies can equip themselves with a glass tempering furnace. For a medium/small glasswork, this type of machinery can really make a difference, but a wrong purchase can even sink a craft enterprise.

That is why it is essential to choose a model that is designed precisely for the needs of a small company. What does a tempering furnace have to guarantee to support a small glasswork in its growth?

Investment Protection

The performance of the furnace is obviously essential to ensure that the glassworks can do the work it no longer wishes to outsource. But since this type of machinery is not purchased every day, it is also essential to pay attention to the economic aspect.

A small/medium-sized glassworks must therefore purchase a furnace that not only requires an initial outlay that is not excessive, but above all that can guarantee both a long service life and a good residual value after several years of use.

Opting for a product made from first-rate materials by an experienced and qualified company is certainly a great way to protect your investment and quickly turn it into profit.

Optimisation of glassworks space and equipment

Choosing a tempering furnace model that does not take up excessive floor space is very important for glassworks that do not have very large rooms.

There are plenty of models that may even offer acceptable performance, but which require brickwork for their installation and are very difficult to move: these are definitely not for a medium/small glasswork.

Attention must also be paid to the electrical installation. Many glassworks have a 200kW electrical cabinet, and the installation of a tempering furnace may require an extension, which involves extra costs and often long months of waiting. That still delays the commissioning of the furnace and therefore the time when the glass can be tempered completely independently.

But there are also exceptions, such as Mazzaroppi’s TP Compact: a super-compact, high-performance oven that can even be installed in the middle of the plant because it is the only model that does not need to be flanked by a wall. Thanks to its excellent energy performance, the TP Compact is also fully operational with a 200kW electrical cabinet.

Ease of use

Small to medium-sized glassworks generally do not have many staff. This is why it is essential that, once the investment has been made in the purchase of a new tempering furnace, there is no need to bring in new people to operate it.

The ideal furnace for SMEs in the glass industry must therefore be user-friendly, easy to manage and as automated as possible. The management software must be intelligent, so as to optimize the information available to autonomously regulate the operation of the machinery.

Unfortunately, finding specialised ‘tempering’ technicians is often not an easy task, and it may not be easy for a small glasswork to find an expert to manage the furnace. Rather, once the furnace has given an extra boost to the company’s business, it may be possible to think about expanding the workforce according to the most frequent requests received from customers.

Energy Savings

Tempering glass is an energy-intensive process, and this is certainly the first deterrent for glassworks, who fear that they will have to pay such high bills that the benefit of tempering in-house is practically non-existent.

Fortunately, there are now kilns on the market equipped with cutting-edge energy-saving technologies, such as just-in-time ignition systems that allow the kiln to be switched off when the glassworks are closed and brought to temperature again the following morning in about half an hour, thus cutting unproductive costs to zero.

And that’s not all: there is also specific software for optimizing the energy required by the kiln, which allows, for example, energy absorption peaks to be contained and ensures very low dissipation.

An example of this is the Mazzaroppi tempering furnaces, whose technological innovations allow the glassworks to save up to 70% energy compared to other furnaces.

Mazzaroppi is the only family that has been dedicated to glass tempering for over 60 years.

Throughout its history, it has registered over 20 patents with innovations that have enabled it to guarantee not only the highest performance for its furnaces but also the best energy efficiency in the industry.
