Witt & Sohn is recognized internationally as one of the best and most innovative fan design and manufacturing industries.

With more than 75 years of work experience, from its establishment in 1945 until today, this complex has been able to create quality and fully engineered devices with creative and fully engineered equipment, despite unlikely innovations in the field of technical design. To bring to our customers both domestically and internationally.

Witt & Sohn with 22 international agencies and successful projects in different parts of the world in the fields, seaports, power plants, tunneling, shipbuilding, industrial plants, environmental protection systems, and renewable energy has been able to complete a resume and Successfully present its performance and Dahi Bandad Group is also proud to announce that it operates as the only partner and official representative of this company in our dear Iran and has used the quality products of this collection in a large number of domestic projects that satisfy its domestic customers.

Comprehensive domain

This group offers one of the most comprehensive ranges of industrial technology for any manufacturer in the world.

The Witt & Sohn fan design approach offers different impellers for each type of fan to ensure the most cost-effective setting can be selected with confidence. Even if the project plans need to be changed, in most cases another license can be used without replacing the entire fan.

Direct drive: Almost all possible working modes with a volume flow from 100 cubic meters per hour to 1,000,000 cubic meters per hour and an increase in pressure from 100 Pascals to 50,000 Pascals can be provided with direct drive with maximum efficiency. The use of frequency converters allows the control of almost infinitely variable variables. The control limits are then set to a maximum per minute to lock the allowable speed or acceleration speed.

V-belt drives: For V-belt drive applications, many options are offered as standard, which is mentioned in the products section.

Other drives: Witt & Sohn fans are also made with different drives via coupling connections, pneumatic, hydraulic, or hydraulic motors.

Materials

Continue to carry out programs and projects that require the highest operational requirements: such as nuclear power plants, naval vessels, chemical facilities, etc.; It has enabled the collection to gain extensive experience in a variety of consumables in construction. Mild steel, aluminum, and various special steels are used as standard materials, although more unusual materials such as titanium have been increasingly used in special designs.

Standard specifications

There is a wide selection of output positions, coating geometries, coating thicknesses, materials, and impellers for all types of fans as standard.

In the analogy and technology section, we will present the innovations used in the design of fans and their differences with common models.
