RLM EVO® (IEC)

Product catalog summary
Overview: The document provides detailed technical information about the RLM Evo® fan series by Nicotra Gebhardt GmbH, focusing on efficiency, acoustics, and ease of installation. It highlights compliance with the ErP Directive for energy-related products and the benefits of using IE3 standard motors.
Specifications: The RLM Evo® fans feature IE3 standard motors with outputs up to 37 kW and impeller sizes up to 1250 mm. They are designed for high efficiency, particularly in larger installations, with aerodynamic properties enhancing performance.
Efficiency and Performance: The fans achieve high efficiency through optimized design and motor power, with larger fans being more efficient than multiple smaller ones. Specific models can reach an overall efficiency of up to 67.4%.
Acoustics: Evo technology ensures low noise levels due to aerodynamic properties, with larger fans operating at lower speeds producing less noise.
Installation and Maintenance: Designed for quick installation and easy maintenance, the fans can be integrated into existing systems with minimal effort and are intended for horizontal axis use only.
Technical Data: Detailed technical data is provided for various models, including motor input power, flow rate, pressure, speed, and efficiency. Operational limits and installation guidelines are according to DIN standards.
Noise Measurement: Noise levels are measured according to DIN 45635-38, with sound power levels specified for both outlet and inlet sides. The proSELECTA program can be used for detailed noise analysis.
Compliance and Standards: The fans comply with the ErP Regulation 327/2011/EU, ensuring high system efficiency and environmental standards. Information on recycling, disposal, and maintenance is included as per operating instructions.
Technical Specifications: The document provides detailed specifications for various fan models, including motor input power, flow rate, pressure, speed, and specific ratio. Installation is according to DIN 24163 Part 1 A.
Efficiency and Regulation: Fans comply with ErP-REGULATION 327/2011/EU, with overall efficiency ranging from 64.3% to 67.4%. Speed control is mandatory for all models.
Operational Limits: Each model has specific operational limits, including maximum fan speed, operating frequency, and temperature range for the conveying medium (-20 to 40°C).
Maintenance and Disposal: Information on recycling, disposal, installation, operation, and maintenance is provided in the operating instructions.
Additional Data: Graphs and tables illustrate air flow rates, static pressure, and efficiency percentages, highlighting performance metrics and operational boundaries for each model.
Technical Specifications Overview: Manufacturer: Nicotra Gebhardt GmbH, Waldenburg, Germany. Various models are detailed with specific technical data.
Installation and Maintenance: Installation according to DIN 24163 Part 1 A, with information on recycling and disposal provided in the operating instructions.
Operational Limits: Maximum fan speed and operating frequency vary by model, with a temperature range for the conveying medium of -20°C to 40°C.
Efficiency and Compliance: Overall efficiency ranges from 68.6% to 70.1%, with compliance to ErP-REGULATION 327/2011/EU.
Additional Notes: Measurements exclude components not part of the fan, and certain areas are marked as "DO NOT USE".
Procedures and Recommendations: Emphasizes proper selection and application of products, advising customers to review operating environments and lubrication requirements.
Standards and Efficiency: Fans are designed to meet future efficiency standards, achieving motor efficiency levels up to IE5.
Application Considerations: Customers should consider operating and performance requirements, with a disclaimer regarding technical advice provided by Regal Beloit Corporation.
Contact Information: Contact details for Nicotra Gebhardt's locations in Germany and Italy are provided.
