Open the catalog to page 1Time is money with the new DDMP you save year after year Low-Noise Solution In addition to their compact design, forward-curved fans are better suited where fan noise is critical. The sound power generated by forward-curved fans is mostly made up by medium and high-frequency noise, providing better sound quality at source, and easier attenuation with acoustic linings The DDM range from Nicotra Gebhardt brought the aerodynamic efficiency of the double-inlet, forward-curved direct-driven fan to an unprecedented optimum, thanks to the combination of the highly-efficient scroll and impeller...

Thanks to this revolutionary choice, and to a careful design, the its basic operation mode: it’s a plug-and-play drop-in unit; The increased compactness of these new motors leads to a new streamlined motor shape design, further reducing computer program and a connection cable, providing variants of...
Open the catalog to page 3currently two single-phase units, of either 1 kW or 2 kW nominal input power, both incorporating an advanced active input stage, providing power factor control (power factor is continuously adjusted to unity). This control mode can compensate a change of the pressure-loss in the air system, e.g. choosing a ventilation unit, or because some filter clogging occurs during the operation of the system. This design also provide harmonics filtering to guarantee requirements for harmonic distortion which apply to data centres. systems, according to EN 61800-3, throughout the range of A. can be set...

As the analogue input channel is needed for the signal Those customers using the fan in a simple for the PID must be set via the Modbus interface,...
Open the catalog to page 5The DDMP range has a downward extension, to relatively tiny fans, of sizes of 146 mm or less, with power input limited to 220 W, single-phase. These fans retain the high operating efficiency of their larger and more powerful relatives, but have been simplified to reduce their cost. The driver is provided with a passive EMC filter, very effective but much simpler than the active unit adopted on the 1 kW and 2 kW units. On these fans there is no Modbus interface, and the operating mode is limited to a simple speed control, with the fan speed proportional to the analogue input voltage (0-10 Vdc...
Open the catalog to page 8Besides the basic DDMP fan, Nicotra Gebhardt can supply a number of accessories, which may significantly simplify the fan installation: mounting feet, suitable for fastening to the scroll side-plates, 13857 and many others. A complete list can be found inside the special catalogue dedicated to the accessories for ATDD-DDM and DDMP fans, freely available from the download area of the Nicotra-Gebhardt website.
