Product catalog summary
Overview: The document provides comprehensive technical specifications and features of the RZR series of belt-driven centrifugal fans by Nicotra Gebhardt, highlighting their flexibility, energy efficiency, and high performance for industrial applications.
Specifications: RZR fans are available in sizes from 0200 to 1600, featuring double inlets with backward-curved airfoil blades. They offer a volume capacity of up to 300,000 m³/h and pressure up to 3,500 Pa. The fans are constructed with galvanized sheet steel and balanced according to DIN ISO 1940 standards.
Design and Compatibility: The fans have identical casing dimensions for compatibility across different impeller geometries, designed for easy installation and maintenance with optimized frame lengths.
Performance and Efficiency: Noted for energy efficiency through advanced impeller design, the fans meet DIN 24166 tolerance class 1 standards. Performance curves and technical data, including sound power levels and efficiency ratings, are provided.
proSELECTA II Program: This program allows users to configure custom fan designs, providing technical data and ensuring only permissible configurations are selected.
Applications and Advantages: Suitable for high-pressure applications, the fans adapt to changing conditions with low noise levels, making them ideal for ventilation and air conditioning units.
Technical Data and Performance Curves: Detailed performance curves illustrate efficiency and operational limits, measured according to ISO 5801 standards.
Fittings and Accessories: Available accessories include drain plugs, access doors, special coatings, and options for Ex-Execution according to ATEX standards.
Key Parameters: Key parameters include volume flow, total pressure increase, static pressure, air density, air medium temperature, shaft power, efficiency, speed, sound power level, and weight.
Corrosion Protection: Fans are treated with high-quality corrosion protection, with options for extreme conditions, including powder coating and wet lacquering.
Mounting and Protection: Fans can be installed with various orientations using galvanized steel feet, with safety measures complying with DIN EN ISO 12100 and 13857 standards.
Anti-Vibration and Noise Insulation: Anti-vibration mounts and noise insulation layers are available for fans operating at higher speeds.
Base Frame and Motor Tensioning: Compact base frames with integrated motor tensioning sliders offer easy handling and maintenance.
Procedures: Flat belt drives offer higher efficiency and quieter operation compared to traditional V-belt drives.
Norms and Standards: Belt guards comply with DIN EN ISO 13857, featuring removable sections for maintenance.
Recommendations: Use proSELECTA II for accurate dimensions and include anti-vibration mounts with AV brackets.
Bearings and Motors: Fans are equipped with self-aligning double row ball bearings and standard motors with protection type IP55. Motors can be equipped with frequency inverters upon request.
Operating Limits: Lists permissible nominal motor power, fan speed, bearing load, media temperature, and fan weight for various models.
Lubrication and Maintenance: Bearings are lubricated with high-performance grease, with maintenance instructions provided for longevity.
Safety and Compliance: Fans come with a "Declaration of incorporation" and comply with the Machine Directive 2006/42/EC. Quality management is certified under DIN EN ISO 9001.
