Efficient retrofit modernization of ventilation systems with innovative technology
Modernize old systems and reduce operating costs
Retrofitting is the retrofitting or conversion of refrigeration, air conditioning or ventilation systems.
We modernise your old systems and ensure noticeable energy savings. By replacing old fans with energy-efficient ebm-papst EC fans, we reduce your operating costs.
One important aspect is that almost every retrofit project is eligible for funding. Germany provides funding that is not being utilised.
It is therefore all the more worthwhile to subject your system to an energy-efficient refurbishment.
The systems to be modernised include air conditioning systems, refrigeration systems, chillers, cooling towers and many other systems in which fans play a crucial role.
We offer you everything from a single source:
1. initial assessment and advice
We provide you with an initial assessment with the help of old device cards, as well as on-site advice and inspection of the systems.
2. measurement
For effective and efficient energy optimisation, we measure the actual electrical power and air performance.
3. interpretation
We use the data to design the required fans or a fan wall. If required, including the necessary peripherals such as sheet metal, canvas supports and switch cabinets including control and regulation technology. With or without data acquisition and monitoring, depending on your requirements.
4. calculation of ROI
We calculate the return on investment for you.
5. offer preparation
We will provide you with a quote with or without conversion.
6. commissioning and documentation
We take care of commissioning, including preparing the documentation and providing the inspection documents.
We offer you everything from a single source:
Control system modernization (PLC, HMI, remote maintenance)

Field reports and success stories from the field
When Dieter Hildebrandt from Breuell & Hilgenfeldt takes on a retrofit
, his customers no longer have to worry. He takes care of the
thinking and planning.
Mr Hildebrandt, you have completed over 100 projects, making you an experienced
Retrofit specialist. How do you approach these projects?
Before a retrofit is implemented, planning and conception are required. Here,
we are at our customers’ side with help and advice. That means we support them
in creating the performance data, develop possible concepts and show
examples – including a rough cost overview. We ask ourselves: What is the purpose
and goal of the system? How should it be operated? And how can we
adjust it?
Do you then also see the retrofit through to the end?
Yes, of course. We plan the entire process and also split it up if
projects cannot be completed within a year. Then
we retrofit the fan first, program the new fans with the
operating point and convert the electrical system in a second step. In consultation
with ebm-papst, we select the right fan and the appropriate motor.
We organise dismantling, installation and the electrical integration into the
system. To be able to compare how efficiency has improved, we take
measurements before and after the conversion.
‘As soon as the plant is 10 to 15 years old, it pays off.’
