EC fans for efficient cooling towers

By OEM Update Editorial February 8, 2019 2:10 pm IST

Cooling towers are used for cooling processes, installations, data centers and buildings. The ebm-papst range now includes axial and centrifugal fans with the appropriate corrosion protection specifically for such applications. Fans dissipate surplus and non-usable heat to the ambient atmosphere. A high air flow rate is required for this purpose. The efficiency is becoming an ever more important criterion, as energy consumption is a significant factor in terms of operating costs.

EC technology marches on
The advantages of EC technology, namely efficiency, infinitely variable demand-based control characteristics, and uncomplicated operating state monitoring via MODBUS RTU, guarantee a rapid return on investments. For use in cooling towers, for example, the ebm-papst portfolio contains a new axial fan with double flange housing of size 1,250 mm, which is particularly suitable for high pressure ranges and is already available for delivery.

Fans withstand corrosion and wear

FanGrid as the ultimate solution
The fans are excellently suited to use in FanGrid arrangement, in other words in a system of centrifugal or axial fans operating in parallel. This offers the advantages of a better air flow through the cooling tower and quick and easy fan replacement. Operational reliability is an essential prerequisite for cooling towers. With an appropriate number of fans, the necessary air flow can always be attained even if one fan is out of operation (redundancy). The speed of the other fans is then simply increased to compensate for the missing air quantity, and the same flow through the cooling tower can be maintained.
