ebm-papst Adds Diagonal Fans for Cooling Inverters and Telecom Base Stations

December 12, 2012 by Jeff Shepard

Diagonal fans are ideal for applications with strict requirements regarding air performance with high back-pressure and small installation space. The new fans of the DV6300 series from ebm-papst now go a step further. Besides improved blower output, the fans with electronically regulated S-Force motor also offer additional functions such as temperature based speeds, active motor cooling, closed loop PWM speed control, and constant speeds over wide input voltage ranges.

The fans have a diameter of 172 mm (6.77 in) on the intake side, making them exactly the same size as the DV6200 range. On the exhaust side, the aerodynamically revised design has a diameter of 190 mm (7.48 in) and an installation depth of 51 mm (2 in) for DV6318/2TDH4P and below performance models. DV6318/2TDH5P has a rotor protrusion of 3 mm (0.12 in). The free-blowing air flow is up to 647 CFM (1100 m/h3), the pronounced pressure saddle is up to 3 in. H20 (750 Pa).

At 83.5 dB(A), operating noise in the high-pressure range is about 8 dB(A) quieter than older models at the same operating point. That is due to various factors, one of them being a flange with noise-optimized links. With an efficiency of 85% for complete motor and electronics, the 350W motor is configured for a long service life at nominal output in all components.

The DV6300 fan series is particularly well suited for applications with high endurance loads, e.g. for motor frequency inverters and switch cabinets cooling, printing machines and heat exchangers. The fans are also highly suitable for the systems requiring multiple different operating conditions such as cooling air requirements of IT/telecommunications; for example base stations, servers, etc. or in power inverters for wind turbines.
