It is important to have good indoor air quality in buildings to ensure clean, pure, and safe (process) air. A well-functioning air handling unit (AHU) is essential for this, preferably with the lowest possible energy consumption. Offices larger than 100 m² must have at least energy label C from January 1, 2023. And according to the new ErP standard, AHUs must contribute to lower energy consumption and reduced CO₂ emissions. Retrofitting AHUs for energy savings can make a difference. Therefore, retrofitting the air handling unit is a wise investment. With retrofitting, we adapt AHUs to meet modern requirements.

How does retrofitting work:

And we do this for only 30% of the cost of a new AHU. An investment that pays for itself!

What does retrofitting yield?

A lot! We know from our customers that retrofitting EC fans, combined with low-resistance filters, can offer significant benefits. The old fan is replaced with a high-quality, smart fan. This fan is up to 30% more energy-efficient, thus reducing CO₂ emissions.

• Lower energy consumption
• Reduced temperature rise
• Adjusted speed
• Longer lifespan
• Wireless system
• Easy to maintain.

Retrofit Step by Step

1. The old arrangement of the impeller housing and motor is completely removed.
2. A pre-prepared mounting plate is installed to which the fan is connected.
3. Holes are sealed, and the floor is finished with a flexible leak-proof casting.
4. Power supply is reconnected (by the Technical Department).
5. Tuning of how the fan is controlled.
6. Control system is adjusted (by the Technical Department).

Efficiency in Air Handling Systems

Based on our experience with numerous companies, the retrofit application of EC fans, combined with low-resistance filters, has brought significant advantages: Low-resistance filters consume less energy, reducing energy costs. These filters result in lower CO₂ emissions and provide up to 35 Pa less resistance. Even a small air handling unit has 6 filters, resulting in substantial savings in both money and energy! After all, 1 Pa equals €1.
