Advanced solutions
for industrial and commercial refrigeration.


For over fifty years STANZANI S.p.A. has been realizing and managing industrial and commercial refrigeration systems. 
The acquired experience makes the company able to offer an excellent service which goes from consultancy and design to assistance services.

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

The rise of energy costs leads STANZANI S.p.A. to seek for competitive solutions, preferring systems with greater efficiency.

By employing all the different technologies available on the market, STANZANI S.p.A. offers solutions focused on its customers’ specific needs without neglecting the importance of environmental sustainability. In fact, STANZANI S.p.A. systems are realized with the following characteristics:

In order to respond to current needs, STANZANI S.p.A. opts for 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.

Ammonia system allows different refrigeration levels: from 2/3°C to -40°C.
This wide temperature range allows the system to have great flexibility, both during the design phase and the day-to-day conduct phase 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 this is an extremely rare event).
In fact, STANZANI S.p.A. technical staff belonging to the Refrigeration Division is specifically trained and equipped with the necessary tools and qualifications to handle toxic gasses.

Consequently, the use of ammonia would be a widely safe and convenient process, which would definitely meet current technologies and legislation.
