In refrigeration and cooling installations, any residual heat created must be expelled to the surrounding air through heat exchangers. Fans, therefore, pump cold air through the heat exchanger to improve the heat dissipation. There is a whole range of options for designing and configuring efficient, quiet and durable fans. A new, passive component, the so-called AxiTop Diffuser, provides for a substantial improvement in efficiency and noise. Its pressure-boosting effect minimises exit losses and makes it easier to adapt the fan to commercially available heat exchangers.
ebm-papst is going one step further. AxiTop - the diffuser for axial fans - substantially reduces losses downstream of the impeller outlet.
