RETROFIT FANS: TURN OLD INTO NEW!

Make existing systems more efficient with retrofit fan replacement from ZIEHL-ABEGG

The ZIEHL-ABEGG retrofit programme ensures modern and efficient fan replacement in old ventilation systems. But that doesn't mean you need to buy a completely new system! That’s the great thing about retrofitting with ZIEHL-ABEGG: Your overall system or machine remains largely unchanged, with only the individual components being replaced by modern and more economical fans.

In the field of ventilation technology, a distinction is made between the following applications:

Heat exchanger

Systems like this are often used in industry or manufacturing, but have also become indispensable in agriculture and the food industry. Heat exchangers are located on roofs or facades of supermarkets and are used to cool media such as water or refrigerants in the outside air.

Ventilation units

These fans (known as air handling units or technical room systems) are usually found in systems for the ventilation of offices, shopping rooms, shopping centres or hotels

 


Go to ZAcube

Our focus is on you! As a ZIEHL-ABEGG customer, you benefit from retrofit fan replacement:

Modernisation: With retrofit fan replacement, you not only gain a modern ventilation system that meets the latest energy standards, but you will hardly hear it.

Costs Up to 50% of energy use can be saved by retrofitting your ventilation systems.  For you, this means: Lower operating and maintenance costs.

Safety:  Replacing old fans with modern fans guarantees increased reliability, as in most cases the large old fans are replaced by several EC fans that are operated in parallel.

Sustainability: Improving the energy efficiency of your renovated system technology reduces CO2 emissions. This makes an important contribution to the environment.

Health: Because ZIEHL-ABEGG retrofit fans are not belt driven, no rubber abrasion can enter the air cycle. This allows you to effectively reduce maintenance costs and also ensure “healthy” air.

It is a question of budget? It doesn't need to be, because the costs of modernising your ventilation with retrofit fans will be kept within reason, we promise! Fan replacement is also supported by promotional programmes such as BAFA and KfW. We would be happy to advise you. Schedule an informative meeting with our experts now.

Project: Coolers

At one of Germany’s largest computer centres, 64 unregulated AC axial fans were replaced by high-efficiency ZAplus units coupled with ECblue motor technology, thus providing energy-efficient fans on the coolers.

Performance & Savings

Modernisation of a hospital ventilation system in Lower Saxony

How retrofitting a fan replacement is good for people and the budget:

The hospital facility was modernised in just 1.5 days. New fans replaced the predecessors from 1994. In addition to reducing operating and maintenance costs, there are also health benefits of retrofit fan replacement because the new fans run without a belt drive. As a result, both hospital staff and patients no longer breathe in rubber particles (fine dust).
