Plug & Play
The ECFanGrid retrofit kit is a ‘plug and play’ solution that reduces the installation time & labour on your retrofit project. Rosenberg’s ECFanGrid kit includes, the fans, a grid layout, inlet cones and cone plates, mounting supports to create a structure, sheet metal fill plates and all of the assembly hardware. We offer a pre-assembled Control Cabinet complete with circuit breakers and an additional 24V power supply that saves time on-site.
No expensive building envelope renovation
An ECFanGrid consisting of several smaller fan units is designed to replace a large single fan.
Components are small enough to easily move through existing doorways.
No need to rent expensive equipment like a crane.
Reduce downtime during retrofits
On some projects, it is possible to install an ECFanGrid while the single original fan is still operating.
We provide the drawings and documentation
you need to ensure that the installation and commissioning of the ECFanGrid is a well managed process.
Easy access for service
When an ECFanGrid is installed in an AHU or HRV interior space is gained, inside the cabinet that allows easy access for service personnel to do preventative maintenance or replacement of modules.

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, 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 & 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.
OEM Designs & Customization
Rosenberg Fans Canada Ltd. has lots of experience working with equipment manufacturers across Canada. Ask one of our technical sales people how our design and customization program will support your design team.

FEATURES
Equipped with EC motors
The ECFanGrid assembled by Rosenberg is the only one of its kind using EC motors. This gives our grid unique advantages and benefits over those of other fan arrays using standard motors.
Multiple fan array configurations and sizes
From two to more than twenty fans either with our ready to use Unobox or ECFanGrid retrofit kit, we can insert our ECFanGrid into any existing enclosure in combination with our multiple fan sizes. Our ECFanGrid can deliver the air flow and pressure that your application demands.
Compact, light & flexible
Retrofitting and designing ventilation systems with the ECFanGrid will accommodate smaller footprints compared to systems using standard belt driven fans.
EC fan retrofit kit
The unique Rosenberg fan array solution includes everything within our EC Fan Retrofit Kit required to make your next retrofitting project a big success using a single source.

Unobox: Stackable modular self-contained fans
The Unobox is an assembly consisting of a backward impeller EC fan mounted inside a sturdy box. It is a Rosenberg’s approach to modular construction of a grid as a stand alone unit, or in a case when a previous casing no longer exists. Constructed out of an extruded aluminum frame with thermally and sound insulated galvanized steel panels. Powered by our energy efficient and easy to control EC motors.

BENEFITS
1.
Ease of control & versatility
Previous
Next benefit
Electronically commutated motors (EC motors) 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 & Reliability
Retrofitting 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 600 V power adapter module, grills, potentiometer & local controllers with transmission capabilities and more. This is a one in all Rosenberg solution.
ENERGY SAVING
Energy saving technology.
Rosenberg 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 commutation motors (EC) are not only efficient in their operation, the embedded technology also allows the motor speed to be fully controllable by different room variables such as differential pressure, temperature, occupancy, time etc., without the complications of a VFD this allows the overall system to have and extraordinary precise energy usage allocation.
RETROFIT
Multiple provincial incentive programs for the installation of VFD’s delivered by local hydro companies are available for retrofitting commercial, industrial and residential ventilation systems, Rosenberg EC fans are in compliance with this retrofit incentives in different ways,
- Variable Speed Control Ready
- Multiple Control Configurations with easy set up. (Peak demand Timer, differential pressure, temperature etc.)
- Less Power Consumption at the same operating point if compared with an AC motor. view comparison table
