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

STANZANI S.p.A. has an internal workshop, equipped with technologies and machines, which is specialized in refrigeration compressors and electric motors overhaul.
The customers’ service is available 24/7 for 365 days.
The first step of the systems analysis consists of remote connection. This makes it possible to intervene via software to resolve malfunctioning problems.
In the most serious cases, a team of specialists with equipped vans would be available in a very short time.
The call center is available 365 days a year and it answers exhaustively to any aspect concerning technical management of the systems.
5. Refrigeration systems realization
The technical-commercial office of the Division manages and deals with every single step between the customer and the company:
- First estimate of investment costs;
- Development of a project;
- Creation of a quote based on the project;
- Realization of the executive project;
- Completion of procedures and legal authorizations;
- Commission management (provisions, construction site, and accounting);
- Start-up and tests;
- Work delivery to the customer (with declaration of conformity);
- Post-delivery work management.
6. Refrigeration systems repowering
The technical-commercial office offers a full service concerning the existing systems repowering.
7. Refrigeration systems requalification
The technical-commercial office provides a full service concerning the requalification of existing systems - e.g. HCFC and gas systems retrofitting.
8. Aging and drying systems
The technical-commercial office deals with planning and realizing the aging and drying systems for cheese and cured meats in static or dynamic rooms, thanks to the decennial experience acquired in this sector.
9. Fleet of refrigerating machines rent
In case of emergency, STANZANI S.p.A. also provides a fleet of refrigerating machines to the customer. It is composed of chillers, that are able to generate power up to 1.000kw, and air-handling units, whose assembly, dismantling and management are guaranteed by STANZANI S.p.A. staff.
In order to resolve any kind of technical problem or any problem concerning spare parts, STANZANI S.p.A. has always promoted a philosophy focused on partnership, created both with the assemblers and the mother companies.
STANZANI S.p.A. goal is supplying an exemplary service on a quality level. As a consequence, STANZANI S.p.A. deserves credits for having become a concrete reference for those who want to develop their own business on sound foundations as well as to ensure the loyalty of continuously satisfied customers.
