A Rosenberg ECFanGrid consists of series of EC fans used in parallel. The resulting air flow is proportional to the number of fans used, with the pressure conditions remaining the same. Fan units can be joined in any quantity or arrangement – 1×3, 2×2, 2×3, 3×3 – for virtually limitless application flexibility.
The use of electronically-commutated (EC) fans is not only highly efficient, but they form a perfectly matched unit for a cost-effective “plug and play” solution for individual ventilation requirements.
When applied in a typical air handling unit (AHU), a Rosenberg ECFanGrid offers excellent possibilities to optimize all available floor space. compared to a single large radial fan, space savings up to 50 % can be realized. Further, the distribution of the air velocity over the entire duct is much more even. This increases the efficiency of downstream components and compensation sections can be made shorter.
When a redundant system is a requirement, the Rosenberg ECFanGrid is the logical choice. For example in a data center, a total system shutdown would result in massive costs. The common approach to get redundancy is to place a second identical system beside the operating unit. Not only is this inefficient, but also doubles the required footprint. However, if one fan fails when a redundant ECFanGrid is used, the remaining fans can maintain the operating point by having their speed increased. In addition only the open cone has to be closed.
A Rosenberg ECFanGrid is also ideally suited for the use in retrofit projects particularly where a single large radial fan is being replaced.
