Fans and Blowers

Industrial Fans & Blowers

Industrial fans and blowers are designed according to customer applications making them highly adaptable and customisable.

The single stage SiccaDania Fans and Blowers are selected according to client specification. Basically, the fans and blowers have the same geometrical configuration but differ in the application and static pressure rise:

  • The fans are used for conveying air or a gas type media at medium to high flow rates up to 700,000 m3/h and/or at pressures up to 200 mbar(g).
  • The blowers have a low to medium flow, deliver a higher static pressure rise up to 500 mbar(g) in a single stage and are, in many cases, used for either incinerator operation or convey special or toxic gasses

Typical applications:

  • Downstream Flue Gas or Process Fans for high design temperatures, in many cases with volumetric flows above 200,000 m3/h and with a corrosive gas.
  • Incinerator blowers for maintaining a constant pressure in an upstream or downstream process over the full flow range. This application will typically include an inlet vane control, recycle lines, blow off valves and an anti-surge monitoring and control system.
  • Tail gas blowers for conveying acid or toxic gasses at a design pressure up to 10 bar(g) and, if required, for a design temperature up to 400 °C. The casing is designed as a pressure vessel and special shaft seals (carbon ring type or dry gas seals) with seal gas systems are used. The casing will be subject to FEM calculations to prove the structural integrity.
  • Fans for ambient temperature below -40 °C (i.e. Russia) with special insulation and bearings and materials selected with guaranteed impact values at -60 °C
  • Dual Drive Fans, driven on two sides by an electric motor and a steam turbine, through special foot mounted one-way clutches and flexible couplings

The operational envelope for single stage fans and blowers:

  • Completely designed and built to client specifications
  • Flow up to 200 m3/sec
  • Differential pressure up to 500 mbar
  • Casing design pressure up to 15 bar
  • Impeller diameter up to 4,000 mm
  • Temperature range from -50 °C- to above +500 °C
  • Designed for various types of industrial gases
  • When required, conform International Standards such as API 560 or API 673
  • Suitable for ATEX zones 1, 2, 21, 22

Since our fans and blower are designed according to the individual application, the following features can be implemented:

  • FEM calculations to prove structural integrity for high pressures or dynamic loads
  • Capacity control through Variable Speed Drive, Inlet Vane Controls or Dampers
  • Noise reduction through silencers, acoustic insulation or noise reducing enclosures
  • Air inlet systems with flow measurement and inlet filters
  • Inlet sand separators for desert conditions
  • Special shaft seals with seal gas systems
  • Condition monitoring
  • ATEX provisions
