Rosenberg
Rosenberg's ECFanGrid series is an efficient and cost-effective alternative to large radial fans for air handling units. ECFanGrid is a line of electronically switched (EC) backward-curved fans that function as a paired unit; it is easy to install, provides high volume and higher uniform airflow with less low frequency noise and built-in redundancy for high reliability.
The ECFanGrid series can be assembled on site, ideal for retrofit projects, especially when replacing a large radial fan.
Rosemberg offers two construction options for fans: fan modules mounted on a pre-designed frame or a UNOBOX design, which is self-supporting and expandable.
Ventilation units can be joined in any quantity or arrangement: 1x3, 2x2, 2x3, 3x3, for greater flexibility in application. All units within the network work together for easy implementation of airflow, pressure or temperature control.
