Rosenberg’s new 560-mm backward curved fans with size 6 Gen 3+ EC motors deliver all the features and benefits of our innovative Gen 3 motors plus more cooling power. The Rosenberg GKHM 560-CIG.160.6NA Gen3+ (PN # N88-56604) comes standard with 7.2kW 3~ 460V EC motor, coupled to a super-efficient impeller. Airflow at 460-Volt exceeds the two “magic numbers” of 6 kW fans for data center cooling and high-efficiency HVAC: 6000 cfm @ 6” of pressure and 8000 cfm @ 4” of pressure.
The new fans are in stock now, available for immediate shipment.
Rosenberg’s new EC motors are 30% more powerful than the previous “Generation 2” motors of the same size. They offer a standard input voltage range of 200-480 VAC (50/60 Hz) and automatically adjusts to the actual input power across the entire range, allowing reduced inventory cost and easier design-in. Data on the new “Gen3” fans are included in Rosenberg’s fan selection software, RoVent10.
Other standard features include:
• Integrated inspection LED to visualize the motors condition. It is visible from the outside through the composite material of the cover of the motor.
• Improved ModBus RTU functionality. The motor not only measures its current power consumption, but also continuously records total energy consumption. A detailed histogram shows the load profile of the fan as well as the temperature at which the fan operates over time. This makes it easier to evaluate the operating conditions of the selected fan and simplifies preventive maintenance.
• Electronic Quick Change Technology (EQC). For replacement or preventive maintenance, it is possible to change the electronic head within minutes and without touching other parts of the fan.
• IT-network (Earthing system) support. IT-network is a configuration of the power grid often used in hospitals and data centers for increasing system fault tolerance.
• 280-680 VDC-Supply. The use of DC voltage becomes more and more common in data centers, due to failure safety and overall design considerations.
