MAP Series
MAP impellers are essential for cooling in thermoelectric power plants and cogeneration facilities, where they provide forced ventilation for cooling towers, steam condensers and air coolers. The optimised blade design makes it possible to handle large air volumes with reduced consumption, while maintaining the efficiency of turbines and generators. The range of diameters up to 12 metres and the modularity of configurations make it possible to meet any plant requirement, ensuring reliability and quiet operation.
Blades:
- Made of extruded aluminium alloy with an aerofoil profile optimised to reduce turbulence and noise.
- Also available in special materials (FRP, PPG) for corrosive environments or ATEX applications.
Hubs:
Types F, P, D, designed for different diameters and loads.
Aluminium alloy or steel structure, with high mechanical strength.
Number of blades: from 3 to 16, configurable according to airflow and pressure requirements.
Available diameters:
- MAP F Series: 350 ÷ 1.000mm
- MAP P Series: 500 ÷ 3.100mm
- MAP D Series: 1.000 ÷ 12.000mm
Blade pitch angle adjustment:
Ability to adjust the blade pitch while stationary to optimise the performance curve.
Operational Technical Parameters
- Maximum tip speed: up to 70 m/s (depending on diameter and configuration).
- Airflow: calculated using Comet Fans software, variable according to diameter, number of blades and pitch angle.
- Dynamic balancing to ISO standards to reduce vibration and extend service life.
Certifications and Standards
- ATEX for environments with explosion risk.
- Compliance with ISO standards for safety and balancing.
- Impellers can be supplied with anti-corrosion treatments for marine or chemical environments.
Competitive Advantages
