New Product: "Dplus Diffuser"

August 16, 2021

Introducing the Retrofiable Dplus Diffuser for Axial Fans

The Dplus diffuser is the perfect retrofit solution for axial fans, designed to efficiently convert dynamic pressure into static pressure. This conversion not only reduces the fan's motor power requirements, thereby cutting down on operating costs but also enables the fan to deliver a higher air volume while maintaining the same power usage as a non-Dplus-equipped fan. Crafted from 1.5 mm thick sheet steel, the Dplus diffuser is available in three colors: red, black, and white.

Key Benefits of the Dplus Diffuser:

Enhanced Flow Range: Optimizes airflow for better performance.
Pressure Conversion: Transforms dynamic pressure into static pressure.
Cost Efficiency: Lowers operating costs by reducing power requirements.
Increased Air Volume: Allows the fan to move more air at the same motor power.
Easy Retrofit: Compatible with existing fans, offering simple upgrades.
Quick Installation: Assembles in just a few minutes, making it hassle-free.

About EC Technology

Rosenberg: Leading the way with energy-efficient EC Technology

Our energy-saving EC motors are developed and manufactured exclusively on our modern production line at our headquarters in Künzelsau. Through the combination of know-how and innovative manufacturing technology we attain a quality that meets the highest standards.

About EC (ECM) Technology

EC (Electronically Commuted, or Electronically Controlled) motors are electric motors which have permanent magnets on the rotor and use electronics to control the voltage and current applied to the motor.

EC motors have no brushes, so avoid the sparking and short life of brushed motors. Because they have electronics controlling the stator, and do not need to waste power inducing the rotor field, they give better performance and controllability, and run cooler than induction motors (for small motors, at least: high horsepower 3 phase induction motors can be very efficient). EC motors are used today in many fractional-horsepower applications where high motor efficiency, reliability, and/or controllability is desired.

Advantages:

EC motors are very high efficiency, and maintain a high efficiency level at part speed. This means that in most cases they use from less than one third to one half of the electricity used by the traditional "shaded pole" induction motors used in the ventilation and refrigeration industries, which in turn translates into lower operating costs and short payback periods.

EC motors’ high efficiency also means that the motors run “cool”, and dramatically reduce the amount of waste heat produced. Reduced waste heat at the evaporator motor level also typically results in reduced operation at the compressor level, which allows further energy savings. Further, running cooler improves the life of highly loaded motor parts like windings and bearings.

EC motors also have a wider operating range than traditional induction motors, which means that one ECM motor can replace a number of induction motor models. In this way, the number of models required by a typical customer is significantly decreased, which decreases and simplifies inventory. This is the main reason why ECM product lines usually include less motor models than their induction counterparts.

In terms of speed control and features, because the motor’s operation is controlled by software, EC motors allow customers to optimize and integrate the motor, fan and controller with the application, and to include features like data communications, constant volume control, variable speed, etc.

EC motors are also quieter than traditional inefficient motors, have longer design life and require less maintenance.

Quality pays for itself. The slightly higher investment costs compared to conventional motors is usually amortized within a short operating time due to lower energy consumption und greater ease of installation. No transformer controller, motor overload switch, thermocouple meter, VFD, or phase angle controller are necessary.
