DDMP

Scroll casing with direct drive and forward curved blades - double inlet

Product Description

Integrated efficiency advantage

The EC-motor operates without slip losses and thus consumes significantly less power than conventional AC motors.

Important: This applies for all speeds, i.e. even in partial-load operation! The EC-motor therefore uses less power than the AC motor under all operating conditions and has a significantly higher level of drive system (motor and control) efficiency.

Energy saving concept

New high efficiency EC-motor
New compact and streamlined motor design
High intensity neodymium magnets
No obstruction of intake due to build-on control unit - less aerodynamic losses

General Features

Sensorless control
Simple installation due to plug and play
IP 54 for complete drive
Designed for double inlet fans

Interface

Analogue interface for speed control
Full MODBUS interface compliancy

High efficiency direct driven centrifugal fan

Product Benefits

Fans in inches:

Double width, double inlet (DWDI), direct drive.
Scroll casing made of galvanized steel (EN 10142), assembled through a high technology roller-locked seaming.
Impeller with forward curved blades of galvanized steel plate, directly mounted on a brushless, permanent magnets, DC-external rotor motor, no transmission losses, dynamically balanced according to ISO 1940.
High efficient 1000 W driver sensor-less algorithm, with integrated active PFC and thermal derating protection, is directly mounted on scroll, plug and play solution, no need further configuration.
