The ‘XHP’ fan is designed for high pressure purposes, while maintaining optimum efficiency. This model is used in small industrial plants, as well as comfort and industrial ventilation and various filter systems, where high pressure air at small volumes is needed.

 

 

SCOPE

There are 14 frame sizes in the XHP range, and each size is available in various models.

 

The XHP range is suitable for medium and high pressure from 100 Pa to 1,500 Pa.

 

In terms of volume, the XHP range spans from 1,000 m3/h to 15,000 m3/h.

 

The XHP range is designed for operating temperatures up to 600 °C with cooling discs and customized versions are available.

 

The impeller can be mounted directly on the motor shaft or on a shaft with coupling and bearings. A solution with belt drive is also available with the motor mounted either above the fan shaft or below on a stand on the common base frame.

 

 

CERTIFIED MATERIALS

As standard, the fan casing is made from mild carbon steel, S235JR (EN10025). The impeller is made from carbon steel, S235JR (EN10025) or Corten steel. The fan frame is made from carbon steel, S235JR (EN10025). The shaft is centreless ground Ceax steel as standard, type C45E. Various shields are made from carbon steel, S235JR (EN10025). Electrode welding with mild steel wire and flux wire (AWS A5.22/SFA 5.22). The XHP range may also be made of Corten-A as well as various types of stainless steel.

 

 

SURFACE TREATMENT

A standard  fan is primed and finished with alkyd top coat RAL 7001 with total thickness of 80 µm. Flue gas fans are finished with black heat-resistant paint. This scheme complies with corrosion class 1. Other colours or paint schemes are available according to the assignment.

 

Fans in stainless steel will be glass blasted as standard. On request, stainless steel fans can be supplied with the surface pickled.

 

 

QUALITY CONTROL

Welding certificates can be presented on request.

 

The fan wheel is balanced in accordance with ISO 1940-1 with a balance quality grade of at least G 6,3. Vibrations on the fan (fan wheel, motor, pulleys, cooling discs, etc.) are tested in accordance with ISO 14694 and ISO 10816-3. The fan undergoes final testing in accordance with customer specifications. Electricity consumption, power consumption, speed and static pressure are all measured.

 

 can perform classification of fan and motor at the customer’s request.

 

 

STANDARDS

The fans comply with the EU Machinery Directive (98/37/EF).
