Applications

Customized burner solutions are designed in conjunction with our customers, by considering the space available and the aesthetic shapes required by the impeller casing.

For burners, flanged motors are normally used, so reinforced casing solutions are needed in order to ensure reliability and long service life. Drying is a key process, and depending on the characteristics of the raw materials, it may be necessary to use impellers made from materials with high hardness and abrasion resistance. Most of our fans serving this sector enhance the filtration system and are appreciated by the leading manufacturers of these systems. High temperatures in combination with acidic atmospheres and possible condensation risks may sometimes require the use of special materials such as COR-TEN or stainless steel. With the aim of improving surface resistance and avoiding corrosion phenomena, dedicated painting cycles are available.

Our fans are also used at cement and lime production facilities. This kind of plant use combustion air, which when heated must be recirculated, extracted and then filtered. Our products can be used in all the processes just mentioned. In addition, for lime production facilities, our fans are utilised in hydration plants and high-temperature gas extraction plants that can reach up to 450°C.

A wide range of well-proven solutions, based on 35 years of experience, suits any requirement. High quality standards, proven resilience, and state-of-the-art design criteria improve customers’ investments in terms of durability and less downtime.

Our products can be found in various processes and applications in paper processing such as drying hoods, heat recovery systems, filtration of dust, fumes and oil mists, and combustion air for burners; in the non-woven fabric industry, for extraction of hot air from tunnel and drum ovens, pre-mixing and air carding; in pulp processing machines for pneumatic conveying, or supporting the forming drum and collectors of dust and shredded material.

Our fans have a sturdy, compact, and modular structure making them an excellent solution that can be adapted to different types of plants without unnecessarily burdening their support structures.

This keeps the inherent vibration level of the static and rotating components of the fan very low and, consequently, the level of vibration transmitted to the structures. In addition to standard configurations, there are specific solutions developed to allow vertical axis mounting up to sizes and powers not permitted by traditional designs.

The diversity of available impeller profiles makes SIA fans suitable for any zone of the plant. Impellers with forward blades are generally used upstream filters in zones with large amounts of dust in the air, while those with reverse blades are appropriate for working downstream filters with clean or slightly dusty air while maintaining very high levels of efficiency. Fans with open impellers, either forward or straight blades, are used in systems that require the conveyance of different kinds of materials in suspension.

There is a very wide range of products with certification to work in explosion-prone zones in compliance with the European ATEX Directive 2014/34/EU. Available solutions include certification of fans and related electrical equipment under different categories that establish how products should be designed and constructed, based on different parameters such as the intensity and duration of the explosion risk or its possible origin (hazards originating from dust or gas).

It is common for filtration and dedusting plants to have important and severe restrictions imposed on the noise emissions from their operation. In this field, SIA fans help keep emissions below the levels specified by the most stringent regulations. To achieve this goal, product design is carried out by considering aspects that contribute to reducing the noise characteristics of rotating machines by acting on the loudness of the sound generated by them.
