Product catalog summary
Introduction
The document introduces the RDP catalogue featuring 230 V single-phase external-rotor, permanent-magnet motors. These motors are noted for their efficiency and compactness, revitalizing the use of double-inlet backward-curved fans in the air-conditioning and ventilation industry through advanced direct-drive systems.
Specifications
The RDP fans feature a direct-drive system, eliminating issues associated with traditional belt-driven fans. They are compact, require less vertical space, and are designed for easy installation and maintenance. The fans comply with ErP standards, meeting EU legislation requirements. The document provides detailed specifications, including power input, volume flow rate, total pressure, speed, and specific ratio. The fans are equipped with integral speed control and comply with Regulation 327/11/EC. Protection class is IP 54 with insulation class F, and they operate within a temperature range of -20°C to +40°C.
Manufacturing and Design
The RDP fans are manufactured using advanced technology to ensure consistent quality. The scrolls are made from galvanized steel, and the impellers are crafted from welded aluminum, offering lightweight, corrosion-resistant, and low-vibration performance.
Advanced Motor Technology
The RDP range includes single-phase and three-phase models, utilizing high-intensity neodymium magnets for improved efficiency. The motors are compact, allowing for powerful installations in tight spaces.
Operating Modes
The RDP fans feature smart drivers with advanced functions, including continuous speed control, PID control, and a Master & Slave mode for synchronized operation. These modes enhance operational reliability and efficiency.
Performance Data
Performance data is provided for various fan models at different speeds, highlighting flow rates and static pressure capabilities. The data is presented for both single-phase and three-phase models, with specific power ratings. Graphs illustrate the relationship between flow rate, static pressure, current, total efficiency, speed, and power.
Compliance and Safety
The drive systems comply with EMC requirements and feature sensorless technology for increased reliability. They include protection features to prevent overloading and overheating, ensuring safe operation. The fans comply with various standards, including EMC requirements for industrial environments and harmonic current emissions.
Installation and Maintenance
Information on disassembly, recycling, disposal, and optimal installation, use, and maintenance of fans is available online. Testing is conducted according to ISO 5801:2007 standards for the specified installation type.
Additional Information
Dimensional drawings, wiring diagrams, and noise data are included for each fan model. The document highlights the integration of a variable speed drive with the fans. The fans have been manufactured since 2016 by Nicotra Gebhardt S.p.A., located in Ciserano, Italy.
Conclusion
The RDP fans offer a modern solution for efficient air handling, combining advanced motor technology with ease of installation and maintenance. They are designed to meet current and future energy efficiency standards.

External-rotor, permanent-magnet motors, although still not always being the best available technology, have set a widely-accepted benchmark level in terms of efficiency and compactness of the drive systems for fans. The availability of such compact drive systems, with a speed intrinsically adjustable and independent from pole number and network frequency, has brought again to the forefront the double-inlet backward-curved fan, a fan type which has long been the mainstay of the air-conditioning and ventilation industry. Notwithstanding the fact that their aerodynamic efficiency still remains unmatched,...
