One of the most successful products for optimising air handling unit installations is the EC Fan Grid. These are EC fans mounted in a matrix that replace older, large fans (usually belt-driven) and thus achieve greater energy and economic savings.
The special distribution of these EC Plugfan backward blade fans achieves the maximum adaptability in each project: one of the main characteristics of Airtècnics and Rosenberg.
The latest example of a Rosenberg retrofit project is the replacement of a large belt-driven fan in a hospital ventilation system with several smaller EC fans installed in a matrix.
This form of installation distributes a more uniform airflow through the duct, which results in higher efficiency of air handling unit components such as filters, heat exchangers, etc.
This redundant system is favourable in case of failure of one of the fans, because the performance of the unit is not interrupted as the other fans continue functioning.
