CARRAT

Air processing analysis for centrifugal fans

The program performs the air processing analysis for centrifugal fans on the basis
of the geometric design entered by the user.
The following types of blades can be considered:

  • BACKWARD-CURVED BLADES

  • BACKWARD-INCLINED FLAT BLADES

  • FLAT RADIAL BLADES

  • FORWARD CURVED BLADES (BLADE ENTRY AND EXIT IN FRONT)

  • “SIROCCO’ BLADES (BLADES WITH ENTRY BEHIND AND EXIT IN FRONT)

The spiral can be assigned by the user or calculated by the program.
The calculation is equipped with graphs of fan performance (Htot-Q,
Nass-Q, h-Q , Lpa-Q where Htot = total pressure, Nab = absorbed power, Lpa= sound pressure level and Q = flow rate), a drawing of the rotor in axial and lateral views,
and a drawing of the spiral (ideal or user-assigned). These dimensional drawings can be saved in AUTOCAD DFX format.

INFORMATION

Caratt can be supplied in the following languages: Italian, Enlish or French.
