Nicotra Gebhardt Retrofit: Efficient fan replacement
The English term Retrofit stands for the replacement of older devices that are no longer produced by more modern variants that meet the same parameters. However, it is also needed for the modernisation of existing systems by replacing older components with more efficient ones. This is not only a matter of function maintenance, but also of energy and cost savings. The Retrofit offer of the well-known company Gebhardt fans also aims in this direction.
What is the savings potential?
With regard to a complete ventilation and air conditioning system, the investment costs for the fan or fans are only around 3% of the total investment costs. When the system is in operation, however, the fans consume 60 to 70 % of the costs. This means that there is indeed great savings potential for industrial companies. As a rule, a ventilation and air conditioning system remains in place for many years without major conversions. During this time, not only were significantly more efficient electric motors developed, but the design of the fans has also progressed and led to more efficient equipment. Especially in this field the company Nicotra Gebhardt is a pioneer.
Therefore retrofit with Gebhardt
Of course there is no den one Retrofit fan. This would also not be possible given the large number of different requirements that occur in practice. Nicotra Gebhardt Ventilatoren GmbH, however, has an incredibly wide range of products at its disposal. Therefore we can make an optimal offer for every application.
Plant optimization in 4 steps
1. rough analysis
Here, all system data is recorded with regard to task, operating mode and operating costs. This also includes the projected design data for volume flow, static pressure, nominal flow and running time of the motor.
2. fine analysis
At this point, all necessary plant data are measured and evaluated. The measured actual values are compared with the target values corresponding to the current use of the building. At this point the optimisation possibilities become visible. On the basis of this data, we are able to offer you the right fans.
We accompany you during the renovation measures and ensure further optimisation by designing the fan drive.
4. final measurement
Renewed measurement of the plant data and verification of the predicted savings effects.
