High Efficiency
EC Motors are the most efficient motors in the market for energy savings and energy-efficient buildings.
Up to 70% of the energy use for the buildings is attributed to the Heating, Ventilation, and Air Conditioning (HVAC).
Energy consumed by the fans is typically the most critical aspect of the application. Replacing the existing belt-driven AC fans in favour of EC-Motor (ECM) fans throughout a building can save half of the HVAC expenses.
Thus, using energy-efficient EC Motor Technology in HVAC systems would be the most favourable direction to take when considering an energy-saving strategy for the entire Property.

FEATURES:
Energy Efficient
We use our variable speed EC fans built with our external rotor motors to lower energy consumption across the whole range of operation. We meet or exceed the European energy standard ErP 2015, the highest in the world. Our EC fans qualify for Canadian and Provincial energy efficiency program grants, loans and incentives.
Uniform Airflow
The ECFanGrid delivers uniform airflow. This improves efficiency by reducing turbulence across heat exchangers and through filters.
Easily Controlled
Our EC motors allow the ECFanGrid to be variable speed. Using control signals (0-10V or 4-20mA) from sensors or Building Management Systems, the ECFanGrid will automatically adjust to changing conditions. Using control sensors automate your system to adjust for differential pressure, constant airflow, temperature, carbon dioxide (CO2), fault detection, emergency alarms and more.
Cost-savings — Compact
The smaller footprint of the ECFanGrid can reduce the space requirement for the fans by up to 70%, as compared to a single large fan. Reduce your costs to produce your equipment, reduce the customer’s space requirement for your product and free up space.
Lighter
Compared to traditional systems that use single large fans our ECFanGrid is lighter. This means less mechanical load on support structures and may reduce construction costs as well as equipment installation costs.
Quieter
The total sound power of the ECFanGrid is the same as other systems but the frequency spectrum is higher. Higher frequencies require smaller attenuators, which minimizes the space needed for the air handling systems.
Redundant Specifications
Some customers require extra capacity in their critical system applications such as hospitals, data centers, schools or other public facilities, The system design strategy that uses multiple fans, will provide your system with fault tolerant operation and eliminate downtime. Systems can be designed to allow for service to filters or replacement of fans while the air handling system is running. Explore the cost-saving advantages and possibilities that multiple fan systems offer when customers ask for redundant fan systems.

BENEFITS
1.
Ease of control and versatility
Previous
Next benefit
Electronically commutated motors (EC motors or ECM) integrate the advantages of electronics to:
Drive – directing power electronically to different coils is what drives the motor, this makes the motor extremely efficient in the usage of energy.
Control – intelligent technology that allows the motor to be controlled with ease. Speed can be controlled by the use of a simple potentiometer (0-10 V) in (open loop) with a secondary setting (closed loop) to make speed dependent on any external condition (differential pressure, temperature, humidity, etc.)
Power – Rosenberg motors can handle 120 V single phase, 230-460 V three phase and up to 600 V with our dedicated transformer for the Canadian market.
EC motor powered fans are efficient, intelligent and versatile.
Redundancy and Reliability
Retrofitting HVAC with our ECFanGrid instead of a single fan provides reliability and redundancy as well as flexibility for any given ventilation system. If one fan fails the remaining units on the grid will pick up the lack of air flow. The fans will increase speed and hold at the desired setting until the fan is replaced. In critical applications where constant air flow is required, this feature offers a sound solution and much more reliability than a single fan, no downtime when failure or servicing.
Flexibility
With our multiple EC motor and plug fan sizes, the Rosenberg ECFanGrid or Unobox are able to adapt to any type of grid depending on the geometry of your actual installation. The combination of impeller size and motors will provide the desired output on flow and pressure.
Ease of handling and installation
Due to the compact size and weight of Rosenberg’s ECFanGrid retrofit kit and Unobox, the fans are easy to move, lift, and place into difficult and complicated spaces. This is a huge advantage over larger and bulkier single fan retrofit installations where demolition, lifting, and special equipment is required.
One stop source for all components
Rosenberg ECFanGrid retrofit kit includes: our analysis on how to accommodate the grid; the mechanical performance calculations including electrical and power consumption; drawings and documentation; the required fans and inlet cones; adaptive structural supports for complete stability (top, bottom, side and between components); sheet metal fillers; complete wiring cabinet with protections and supplementary control power supply. Optional components include 600V power adapter module, grills, potentiometer and local controllers with transmission capabilities and more.
This is an all-in-one Rosenberg solution.
ENERGY SAVING
Energy saving technology.
Rosenberg's ECFanGrid is the most energy efficient HVAC system available on today's HVAC market.
Our research team is constantly working on innovations. Our fans powered by motors with the modern EC technology achieve efficiency ratings over 90% and can save up to 50% in energy consumption versus traditional motor technology (in accordance to EC 60034-30) with energy rating greater than IE4.
Electronically Commutated Motors (ECM) are not only efficient in their operation, but without the complications of a VFD (Variable-frequency drive) the embedded technology allows the motor speed to be fully controllable by different room variables, such as differential pressure, temperature, occupancy, time, etc.
This allows the overall system to have an extraordinary precise energy usage allocation.
Check Rosenberg's EC-Motor fan selection.
HVAC RETROFIT
Multiple provincial incentive programs for the installation of VFD’s delivered by local hydro companies are available for retrofitting commercial, industrial and residential HVAC systems. Rosenberg EC fans are in compliance with these retrofit incentives in different ways:
- Variable Speed Control Ready
- Multiple Control Configurations with easy setup. (Peak demand timer, Differential pressure, Temperature, etc.)
- Less Power Consumption at the same operating point if compared with an AC motor. view comparison table
Our ECFanGrid is a multiple fan array that was born for HVAC Retrofit. Unlike "FanWall" systems by Nortek, who buy AC motors from someone else, we build and use our own EC motors. Rosenberg's EC motor (ECM) technology is more compact than AC motors, and our built-in speed controls are more energy-efficient than VFDs used with AC motors. Our speed controls are fully variable from stopped to full-speed and save more energy as the speed is reduced. VFDs only operate down to 50% of full-speed and become less energy-efficient as they reduce the AC motor’s speed. Our EC motors power our ECFanGrid to make it the most compact, energy-efficient and truly 100% variable speed multiple fan system available on the Market today.
Our goal is to provide our customers with all the tools needed for a successful HVAC retrofit project. With our Rosenberg Retrofit Kit , we deliver all the elements to fit the ECFanGrid inside the plenum of any existing Air Handler (AHU).
Consider Rosenberg’s ECFanGrid for your next HVAC Retrofit project.

Task
Replace the old belt-driven fan rated (125 HP motor operating at 50,000 CFM @ 1.5” of total static pressure).
The ball bearings in the motor have been replaced 4 times in the past 5 years causing significant downtime and at a total cost of $40,000.
Result
Rosenberg Fans Canada’s retrofit solution uses our 3 Х 3 ECFanGrid.
Our system’s total power is only 42 HP to produce 50,000 CFM at 1.5” of total static pressure. That’s 1/3 of the original motor’s 125 HP power, which will translate into significant power and electricity cost savings. No maintenance is required for EC fans and the system can be running when a fan needs to be replaced.There should be no system downtime, ever.
ECFanGrid control has been seamlessly integrated into the existing building management control system.
