ebm-papst Wins the ACHR News Dealer Design Bronze Award in the Refrigeration and Ice Machines Catagory for the Diagonal Flow Fan Module with Handheld Programmer

Product Description:

The diagonal flow fan module was designed for use in refrigeration applications such as refrigeration plant condensers/evaporators, food display cases, beverage coolers and freezer cabinets. This programmable diagonal flow fan module has all needed components integrated into a single package. The entire drive and control electronics are contained in the motor enclosure, where they are sealed and protected from the moisture and cleaning solvents often found in refrigeration environments. Two default fan speeds are supplied as standard and can be quickly reprogrammed by the end user in the factory or in the field using a battery operated handheld programmer specifically designed for this purpose.

The fan module includes the drive motor & control electronics, the impeller & inlet ring and the support housing. A flange integrated into the housing allows quick mounting to any flat surface via multiple thru-holes. A removable power cable plugs into the motor with a water-proof connector and is available in four standard lengths. Reprogramming of the two factory programmed fan speeds can be done using a single cable connected between the handheld programmer and the fan through a keyed port near the fan power plug. The complete fan module is maintenance free.

Competitive Difference:

Most air movers for this market are axial fans that need to be purchased and assembled from separate components - motor, propeller and housing. These axial propellers are typically simple stamped metal blades that can only provide air flow against limited static pressure. This product not only offers an integrated assembly and speed programmability by the end user, it is also the only product to use a diagonal flow impeller design (a type of centrifugal impeller). Such an impeller allows operation at higher static pressure and the semi-radial discharge can improve air flow in applications where the straight through air path of an axial fan is restricted.

Installation & Service Benefits:

- integrated assembly eliminates the need to purchase or service individual components
- quick install using the mounting holes in the built-in flange
- completely maintenance free
- speed programming by the user provides application versatility and duty point matching to achieve the lowest power usage
- battery operated handheld programmer makes quick work of the speed programming
