Rosenberg EC backward curved fans are now available in 5.5kW models.

Five sizes of Rosenberg's electronically commutated (EC) backward curved fans are now available with 5.5 kW motors for greater power and efficiency. The new fans feature three-phase motors with nominal input voltages of 230V and 460V. They are 100% speed controllable and are CE, UL and RoHS approved.

Other features include closed motor protection class IP 44/54 for reliability in humid environments, and thermal contacts wired into windings for motor protection. Standard maintenance free ball bearings, closed on both sides, are sealed for life.

The range of sizes for the new KH Series fans includes 450 mm, 500 mm, 560 mm, 630 mm and 710 mm fans. They deliver up to 7 inches of water gauge of static pressure or up to 14,000 CFM of airflow at free air, perfect for a wide range of HVAC and air movement applications.

Their highly efficient free-running impellers are made of saltwater-proof aluminum and are balanced according to quality class G 2.5, DIN/ISO 1940. The fans can be supplied as complete modules equipped with airflow optimized inlet cones. Module enclosures and inlet cones are made from galvanized sheet steel.

Rosenberg backward curved EC fans feature extended-life, low-temperature brushless DC motors that are controlled by maintenance-free electronic circuitry. Because of reduced mechanical content, electronically commutated (EC) Rosenberg fan motors run cooler and quieter.

Rosenberg backward curved fans can also be made to customer-defined specifications including airflow, power, rotational speeds, noise level, overall dimensions and finish.
