Conditioner - Import export

Air conditioning is the operation by which the parameters of relative humidity, temperature and air speed are modified. For this sector, our company deals with the production and sale of copper and iron pipes which can be semi-finished or assembled suitable for different purposes, including: Improve people's well-being. Maintain suitable environmental conditions for the correct conservation of everything that is subject to temperature variations and requires a constant temperature. Allow the correct operation of equipment, removing the heat generated by use and maintaining the temperature constant for correct operation.

ALMAQ is a formulation that stimulates plants to develop endogenous defense mechanisms, making them more resistant to biotic and abiotic stresses. Due to the presence of nitrogen and phosphorous, the product prevents and cares nutritional deficiencies and reinforces the tissues which will be more resistant to physical and mechanical stress agents. In addition, specific plant extracts stimulate the plants to produce phytoalessine, which are natural endogenous substances that create unfavorable conditions to fungine and bacteria. The formulation is particularly recommended for vine crops.

FERTHUMIC is a liquid fertilizer with humic and fulvic acids enriched with seaweed and micronutrients completely chelated by EDTA. The synergism between the seaweed and the humic substances help enhance the soil´s cation exchange capacity in order to obtain better results at a physical, chemical and biological level. Its application is linked to key moments such as leaf formation and development, pre-flowering, fruit set, bulb enlargement, bud formation, and any stress condition that may occur.

KOVER increases the resistance of plants to the sudden lowering of temperature (frost), and to the excesses of summer heat that cause water loss and dehydration (summer evapotranspiration). This product is able to increase the concentration of specific elements that have a recognized anti-stress action on the inside of the plant, and it promotes the formation of a gas-permeable film (antiperspirant) that is able to reduce water loss through the leaves. In addition, KOVER also contains the polysaccharides that makes the plants able to survive in extreme dehydration conditions.

OSTRO C is the Vtype condenser for high power refrigeration, air conditioning and industrial processes. OSTRO can be configured in 3 solutions Dry, Spray and Pad. In the Spray and Pad versions with water injection, the power increases are very significant and guarantee a legionnellafree solution.

Our company has been manufacturing finned coil heat exchangers for over 40 years. The design of each finned pack can be totally developed inhouse by Stefani or taken from a drawing supplied by our customer. This is possible thanks to a strategic coengineering service, which is necessary especially when developing specific designs. In the design and manufacture of our finned coil heat exchangers we put all the flexibility and competence that have always been the hallmark of our work. We make customised finned packs for production in batches, dedicated to the machines of our OEM customers and, in general, to data centres, air treatment units for industrial refrigeration, industrial and commercial air conditions and condensing units for refrigeration.

OSTRO W is a product range designed to meet the needs of high capacity exchange in dry cooler and condenser operation for the industrial process, HVAC air conditioning and refrigeration. With the PAD or SPRAY versions the capacity increases, thanks to water injection, are very significant and guarantee a legionellafree solution.

ZONDA is the new Vtype singlerow dry cooler allow heat exchange designed for limited space availability or visibility on the roofs.

SCIROCCO C is the new tabletype condenser for refrigeration, conditioning and industrial process applications.

GRECALE was created with various types of industrial refrigeration applications in mind. Thanks to a very wide range, GRECALE meets the needs of installers who need the maximum technical and economic competitiveness. The new series has uncompromising structural quality and a highperformance exchange core, it is rich in configurations and accessories and has been optimised to increase space for goods in the cold store. For consumption efficiency, the version with hot gas and water defrosting is available, even for low temperature cold stores.

ZEFIRO is the new dual discharge air cooler for refrigeration applications, especially for processing rooms or environments that require a double flow of air.

BREEZE is the new angled air cooler for commercial refrigeration, in particular for small cold rooms.

The new commercial cubic air cooler BOREA is the first project developed according to Stefani’s new philosophy. The company redesigned its heat exchangers to obtain maximum efficiency and thermodynamic performance. There are 192 models and plenty of accessories in the range, including water defrosting for the largest commercial sizes.
