Custom-made environments for your business 

For over fifty years STANZANI S.p.A. has been realizing and managing industrial and commercial refrigeration systems. 


This makes our company able to offer an excellent service from consultancy and design to assistance services.

STANZANI S.p.A. designers and engineers’ knowledge are constantly upgrading: this allows targeted interventions on ammonia systems, freon gas systems and systems based on a salt solution as a carrier fluid for conservation and transformation of the following products:

• Fruit and vegetables;
• Fish;
• Zootechnical products;
• Agricultural food products;
• Dairy products;
• Wine products;
• Pharmaceutical products.

The rise in energy costs leads STANZANI S.p.A. to seek for competitive solutions, preferring systems with greater efficiency. Employing the different technologies offered by the market, STANZANI S.p.A. offers solutions focused on its customers' specific needs without omitting the importance of environmental sustainability.
In fact, systems are realized with the following characteristics:

• Low environmental impact;
• Maximum energy-saving;
• Simplified maintenance;
• Facilitating intervention;
• Low cost and easy finding spares parts;
• Supervision for local and remote systems control.

In order to respond to this need, STANZANI S.p.A. opts for the use of anhydrous ammonia (NH3) as refrigerating gas for industrial systems. Ammonia has thermodynamical and environmental beneficial properties and offers more advantages than the common freon gas.

First of all, ammonia is a natural gas, easy to produce, abundantly available and inexpensive. As a consequence, it doesn't produce any greenhouse effect or any damage to the ozone layer. In fact, ammonia is one of the most ecological refrigerating gases.

An ammonia system allows different refrigeration levels: from 2/3°C to -40°C. This wide temperature range allows a great flexibility of the system, both during the design phase and the day-to-day conduct as well.

Moreover, ammonia guarantees a definitely higher cooling efficiency than other fluids. Therefore, refrigerating capacities being equal, a greater yield means lower energy costs.

On the contrary, ammonia needs a scrupulous management and regular checks, since it is toxic and flammable. However, its pungent smell and its very low odor threshold allow the experts to immediately recognize a potential gas loss of the system (even if it is an extremely rare event). In fact, the technical staff belonging to the Refrigeration Division is specifically trained and it is equipped with necessary tools and qualifications to handle toxic gasses.

Consequently, with nowadays technologies and legislation, the use of ammonia is a widely safe and convenient process.
