Centrifugal Fans single inlet with direct drive

Product catalog summary
Specifications:
Centrifugal fans with single inlet and direct drive are designed to meet the ErP Directive efficiency requirements for 2013 and 2015. Key parameters include the efficiency grade 'N' for calculating target energy efficiency. Fans are available with backward and forward curved blades, with or without housing.
Efficiency and Performance:
Total efficiency (ηe) is calculated using ηe = Pu(s) / Pe, where Pu(s) is fan gas power and Pe is electric input power. A part load compensation factor (Cc) is applied for systems with speed regulation, with specific Cc values provided for different motor powers.
Product Offerings:
Nicotra Gebhardt offers fan systems compliant with ErP requirements, featuring high-efficiency drives and various motor technologies, including IEC standard and brushless DC motors. The RLM Evo impeller is noted for high efficiency.
Technical Selection Program:
The proSELECTA II program allows users to configure custom fans, providing technical data, sound levels, dimensions, and pricing, ensuring only technically permissible configurations are selected.
Product Ranges:
The TEM range includes single inlet centrifugal fans for HVAC, kitchen, and clean room applications, featuring forward curved impellers and options for ATEX execution for explosive environments.
Technical Data:
Detailed technical data includes motor power, voltage, frequency, current, speed, temperature limits, and volume flow, with performance curves and installation guidelines provided.
Motor Protection:
Motor protection is achieved through bi-metallic releases or thermistor temperature sensors, with rotation direction specified as anti-clockwise (LG) or clockwise (RD).
Construction and Design:
Fans feature a lap-jointed scroll housing made from galvanized steel, with options for vertical or horizontal mounting. Impellers are balanced according to DIN ISO 1940 and are maintenance-free.

The REM series fans are suitable for universal use in various applications, including filter technology, drying, and suction plants, equipped with backward-curved blades and compatible with frequency inverter-controlled operation.
Technical Specifications:
Detailed technical data for direct-driven centrifugal fans includes dimensions, motor protection options, and direction of rotation. Dimensions are subject to change, and motor protection can be achieved using bi-metallic releases or thermistor temperature sensors.
Noise Levels:
Noise levels are provided in decibels (dB) for different models and configurations, measured according to ISO 5801 standards.
Installation and Measurement Standards:
Fans are measured in installation B according to ISO 5801 (ducted), with a media density of 1.2 kg/m³.
Additional Notes:
Various curves and graphs illustrate performance characteristics such as pressure (Pa) and volume flow (m³/h) for different models and configurations.
Overview:
This document provides technical data for direct-driven centrifugal fans, focusing on specifications, performance curves, and compliance with energy efficiency regulations.
Energy Efficiency:
Efficiency data is included according to ErP-REGULATION 327/2011/EU, specifying overall efficiency, measurement category, efficiency category, and achieved efficiency grade at optimum energy efficiency.
Standards and Measurements:
Measurements are conducted according to ISO 5801 standards in a ducted installation, with media density considered to be 1.2 kg/m³.
Dimensional Data:
Dimensions are provided in millimeters, with a note that they are subject to change, including detailed dimensional drawings for installation and mounting.
Key Takeaways:
The document is a comprehensive technical guide for selecting and understanding the performance of centrifugal fans, emphasizing energy efficiency and compliance with European regulations.
Specifications for Frequency Converters:

Procedures:
Installation and operation guidelines emphasize avoiding switching during operation to prevent damage, with special EMC actions advised when combining with isolators.
Standards and Compliance:
Frequency converters comply with EMC standards EN 50081-1 and EN 61000-3-2, with integrated interference suppression filters for various applications.
Recommendations:
Users are advised to consider performance reductions at high clock frequencies and select larger inverter units if necessary, with proper installation to prevent overvoltages.
Technical Data:
Tables provide detailed technical data for various models, including dimensions, weight, and electrical specifications, with wiring diagrams and installation instructions for motor protection units and universal control devices.
Accessories:
Additional components such as isolators, motor protection units, and differential pressure sensors are described, emphasizing their design, function, and installation requirements.
Design and Safety:
Fans are designed for installation in equipment and require protective guards before operation, complying with DIN EN ISO 12100 and DIN EN ISO 13857 standards.
Performance and Usage:
Fans are suitable for air handling and ventilation, capable of conveying air and non-aggressive gases within -20°C to +60°C, using standard motors with IP55 protection and thermal class F.
Explosion Protection:
Fans for explosive atmospheres must comply with EC Directive 94/9/EG (ATEX 95), operating within specified temperature limits and protected against foreign objects.
