Using top-grade materials, such as cast aluminum impellers and hot-dip galvanized steel casings, these fans ensure long-lasting durability. Advanced control systems enable continuous speed adjustments for precise airflow management.
3. Noise Optimization
Rosenberg axial fans feature a sickle-formed blade design optimized for noise reduction. This makes them ideal for noise-sensitive environments, such as office buildings and residential areas, enhancing overall comfort.
4. Versatility and Customization
Available in a range of sizes and configurations, Rosenberg axial fans are versatile for various applications. With adjustable blade angles and customizable control options, they offer tailored solutions that meet specific customer requirements in HVAC, industrial, and commercial settings.
Features and Construction
Rosenberg axial fans are built with several key features that enhance their performance and reliability:
EC Motors: These electronically commutated motors are permanently magnetized synchronous motors designed as external rotor motors. They provide high efficiency and compact, quiet continuous speed control.
Integrated Control Systems: The fans come with integrated EC controllers, allowing for 100% infinitely variable speed control. This feature ensures precise airflow management and energy efficiency.
Protection Mechanisms: The integrated protection mechanisms safeguard the fan from error statuses and overheating. This ensures reliable and safe operation.
Flexible Electrical Connection: The electrical connection options are versatile, accommodating various installation requirements. The supply voltage range designed for 50 and 60 Hz networks allows for a wide range of applications.
Compliance with Directives: Rosenberg axial fans are built with motors that have UL (Underwriters Laboratories) and CSA (Canadian Standards Association) recognition. This certification indicates that the motors meet high standards for safety and performance. The UL and CSA marks provide assurance that the motors have been tested and certified for use in various applications, ensuring reliable and safe operation. This recognition is particularly important for applications in the North American market, where compliance with UL and CSA standards is often required.
Design and Operation of EC Motors
Rosenberg EC motors are designed as external rotor motors, providing several advantages in terms of efficiency and performance. These motors are permanently magnetized synchronous motors, which are highly efficient and compact. The EC electronics transform the alternating current (AC) voltage into direct current (DC) voltage, ensuring precise control of the motor's speed and direction.
The use of permanent magnets in the rotor creates a magnetic field, generating the necessary torque for motor operation. This design allows for quiet and continuous speed control, making Rosenberg EC motors ideal for applications requiring precise airflow management. Additionally, the deep groove ball bearings, sealed on both sides, ensure maintenance-free and low-noise operation.
Motor and Electronic Protection
Rosenberg axial fans are equipped with integrated protection mechanisms to prevent errors and overheating. The motors signal errors through various outputs, such as open-collector outputs or alarm relays, ensuring that any issues are quickly identified and addressed. This feature enhances the reliability and safety of the fans, extending their service life and reducing maintenance requirements.
Electrical Connection and Voltage Types
The electrical connection of Rosenberg axial fans is designed for flexibility and ease of installation. The fans are compatible with a wide range of voltage and frequency-controlled systems, allowing for use in diverse applications. The standard construction includes mounted terminal boxes and optional cable lead-outs, providing additional installation options.
Rosenberg axial fans are designed for use on symmetric and neutral point grounded systems (TN-S, TN-C, TN-CS, TN networks). Other power supply networks may require specific checks for compatibility. The fans can operate in open-loop control, where the speed is controlled by a preselected target value, or in closed-loop control, where the fan adjusts its speed to match the set point value.
Speed Control
Rosenberg axial fans offer various speed control methods to ensure optimal performance for different applications:
Voltage Control: This method reduces the terminal voltage to control the fan speed. It is commonly used for fans in three-phase current construction. By reducing the terminal voltage, the slippage increases, and the speed decreases, allowing for proportional changes in airflow.
Frequency Control: This method uses a frequency converter to adjust the fan speed by reducing the frequency. It is suitable for three-phase fans and allows for precise speed control. The cut-off frequency is adjustable on the frequency converter, ensuring safe operation within the fan's rated frequency range.
Applications of Rosenberg Axial Fans
Rosenberg axial fans are versatile and can be used across a wide range of industries and applications. Here are some of the key areas where these fans excel:
1. HVAC Systems
Rosenberg axial fans are integral components in heating, ventilation, and air conditioning (HVAC) systems. They ensure efficient air circulation and temperature control in commercial, industrial, and residential buildings. The fans' ability to provide precise airflow management and energy efficiency makes them ideal for HVAC applications.
2. Manufacturing and Processing Industries
In manufacturing and processing industries, Rosenberg axial fans are used to ensure proper ventilation and air movement. This is critical for maintaining optimal working conditions and preventing the buildup of harmful fumes or dust. Industries such as food and beverage processing, chemical and pharmaceutical manufacturing, and automotive and aerospace manufacturing benefit from the reliability and performance of Rosenberg fans.
3. Commercial and Industrial Facilities
Large commercial and industrial facilities, such as warehouses, factories, and data centers, require efficient ventilation systems to maintain a healthy environment and ensure the proper functioning of equipment. Rosenberg axial fans provide the necessary airflow and are designed to operate in various installation positions, making them versatile for different facility layouts.
4. Retrofit and Renovation Projects
Rosenberg’s ECFanGrid solution is particularly useful in retrofit and renovation projects. This solution allows for the replacement of inefficient belt-driven fans or outdated air handling units with modern, energy-efficient EC fans. The ECFanGrid ensures improved performance and reduced energy consumption, making it a cost-effective option for upgrading existing HVAC systems.
Rosenberg axial fans reflect the company's focus on producing high-quality and dependable products. Equipped with energy-efficient EC motors, advanced control systems, and strong construction, these fans are built to deliver reliable performance for various industrial uses.
