MEDIUM PRESSURE CENTRIFUGAL FANS

Product catalog summary

Overview: The document provides technical specifications and details for CRL medium pressure centrifugal fans, designed for industrial applications. These fans are characterized by their energy efficiency, low noise levels, and robust construction.

Specifications:

Material: Made of sheet steel with a corrosion-proof polyester resin finish.
Temperature Range: Operates between -25 ºC and +120 ºC, with options for up to 250 ºC.
Motor: Equipped with IE3 efficiency motors for powers ≥ 0.75kW, excluding single-phase, 2-speed, and 8-pole motors. Features include class F motors with ball bearings and IP55 protection.
Voltage: Three-phase 230/400V-50Hz, with special windings available on request.

Technical Characteristics:

Models range from CRL-822-2T-0.33 to CRL-1856-4T-3, with varying speeds, power, and flow rates.
Sound pressure levels range from 71 to 90 dB(A), depending on the model.

Acoustic Characteristics: The noise power spectrum is detailed for each model across frequency bands, indicating the sound levels in dB(A).

Dimensions: Detailed dimensions are provided for each model, including recommended pipe nominal diameters.

Performance Curves: Characteristic curves are provided for flow rate and static pressure, with standard supply orientation and optional positions.

Efficiency: The ErP best efficiency point characteristics are outlined, including measurement and efficiency categories, specific ratios, and efficiency grades.

Applications: The fans are suitable for smoke control systems, ATEX applications, and other industrial uses. They are part of a broader range of ventilation solutions offered by Sodeca.

Contact Information: Sodeca's headquarters and international offices are listed, providing contact details for sales and inquiries.
