The M series:
Impellers with maximum
energy efficiency -
also for retrofitting

Increasing market demands and stricter energy efficiency guidelines require innovative solutions. Venti Oelde is once again setting new standards with the new M series: thanks to a fully computer-aided blade design, it combines maximum performance with impressive energy efficiency. Existing fans can also be upgraded by replacing the impeller – enabling energy savings through retrofitting. Make your system fit for the future now!

Optimisation at all levels.
The strengths of the M series:

Higher efficiency
Higher capacity
Energy savings through retrofitting
Lower noise emissions
Improved running smoothness
Less material build-up

Computer-aided impeller optimisation

 

The development of the M series is based on a modern design process in which the impeller blades are calculated purely by computer. This process allows the blade profile to be designed flexibly and precisely – far beyond the capabilities of conventional methods.

The result:
an optimal impeller design that enables a total fan efficiency of over 90% at the optimum point.

The aim of the development was to design a low-turbulence impeller with higher efficiency, reduced material build-up and lower abrasive wear. Flow simulation of the new M series confirms blade-congruent flow and almost uniform impeller flow.


Goal achieved:
Benefit from higher efficiency and reduced operating costs.

Increasing efficiency in practice

The HRV 63M series - a cement mill fan with a throughput of up to 1,700,000 m³/h - provides a concrete example of the success of the new technology.

Optimisation
Compared to the predecessor model HRV 63S, the new impeller increases efficiency by 4 %.

Energy balance
With a power consumption of 4,300 kW, this means a saving of around 170 kW.

efficiency booster

A key advantage of the new M series: the optimised impeller can be easily retrofitted – without making any changes to the housing, shaft or bearings. The result? A 3 to 5% increase in efficiency and noticeable energy savings.
 
Retrofitting pays off – invest now and reap the benefits in the long term!
