Rosenberg Canada Unveils the I-Series Impeller at CMPX 2024: A Major Breakthrough in Fan Technology
March 25, 2024

In the HVAC world, where efficiency and near-silent performance reign supreme, Rosenberg's unveiling of the I-Series impeller at AHR Expo 2024 marks a significant leap in fan technology. More than just a new product, it embodies a major advancement in design, focusing on optimizing volume flow with its innovative five-blade backward curve. The I-Series redefines industry benchmarks, delivering unparalleled efficiency and dramatically reducing noise levels, reshaping our expectations for professional equipment.

Efficiency: The Heart of the Matter

What stands out with the I-Series is its astounding leap in efficiency. Crafted at the cutting edge of impeller technology, it offers an efficiency boost of up to 11% over its predecessors and rivals. This isn't merely impressive; it's a clear indication of Rosenberg's dedication to minimizing energy use and operating expenses for us, the professionals on the ground. The upshot? Depending on the fan and its usage, this efficiency jump means real energy cost reductions and a step toward greener operations.

The Sound of Silence: A Quieter Operation

When it comes to HVAC systems, the less noise, the better. The I-Series directly tackles this by cutting down noise by over 12%. This significant drop is the result of diligent design refinements aimed at reducing turbulence and vibration—the usual suspects in noisy fans. For spaces where peace and quiet are paramount, like hospitals, offices, and homes, the I-Series is a game-changer, ensuring comfort doesn't take a back seat to functionality.

The Engine Behind the Blade: Gen3 and Gen3+ EC Motors

Rosenberg's innovation streak continues with the introduction of the Gen3 and Gen3+ EC motors, powering up to 7 kW, which drive the I-Series. These motors are the heartbeat of the impeller, melding power with efficiency. This powerful combination spells out an ideal match for a broad spectrum of applications, from air handling units to robust industrial ventilation setups.

A Masterstroke in Airflow Efficiency

Beyond the impeller, Rosenberg's new airflow guide housing for the I-Series modules further elevates efficiency by an additional 12%. This isn't just an incremental improvement; it's a significant leap that translates to nearly $800 in annual energy savings for a typical 560-mm backward curved fan. Moreover, it brings down noise emissions by up to 4 dB, reinforcing Rosenberg's pledge to quieter, more efficient operations.

Broadening Horizons: Applications and Advantages

The I-Series isn't just a product; it's a pathway to transformation across air handling and HVAC applications. It's designed with OEMs and system designers in mind, offering them a leg up in energy efficiency, noise reduction, and performance. Whether it's for commercial or industrial use, the I-Series presents a versatile, high-performance solution that meets the rigorous demands of today's HVAC systems.

Rosenberg's I-Series impeller and its complementary technologies mark a monumental advance in the field of impeller design and performance. By delivering superior efficiency, reducing noise, and pushing the envelope in engineering, Rosenberg is not just raising the bar; it's setting a new standard in the HVAC industry, highlighting its commitment to innovation, sustainability, and excellence.
