Retrofit of old ventilation Systems
A New normal for architecture energy efficiency

The New Normal for Energy Efficiency

Nowadays, the building and superstore field is ushering in a critical period of energy-saving transformation, the '14th Five-Year’ Building Energy Efficiency and Green Building Development Plan and other key policies are also similarly clear that the green and low-carbon transformation of the building.

It is understood that the energy consumption of the HVAC system accounts for about 40%-50% of the total energy consumption of the building, in which there is a huge potential for energy saving, and the energy efficiency of fans and other equipment has become an important indicator for the evaluation of green buildings. ebm‑papst's GreenIntelligence EC products, with their high efficiency, intelligent control and reliability advantages, help ventilation systems achieve a new normal of energy saving.

What ebm‑papst can help you?

Energy-saving

Environmental protection

Energy saving and environmental protection, system efficiency higher than 65%

Compact structure

Integrated as a whole

Simple plug & play, fast installation and retrofit, saving construction time and labor costs

Higher efficiency

Most efficiency

Intelligent control and monitoring, and reducing your daily O&M time and costs, lower energy costs

Easy and safe

Making the retrofit easier

Clearly superior to conventional fans (left) with additional equipment: the GreenTech EC fan (right) – quickly installed and with all features already incorporated.

The electronics and motor form a single unit, which not only saves space but also makes for simple installation. For instance, integrated commutation and control electronics take the place of an external variable frequency drive. And, because the motor and the electronics are already perfectly coordinated in the motor system, there is no need for any additional electronic filters and shielded cables. An external motor protection switch is not required either.

No expensive adjustment work on commissioning, and no grounding and shielding necessary. That’s how easy it is with plug & play.

Applications

Air Handling Units

Cooling towers

Open-heart retrofit

In hospitals, the fresh air supply in operating rooms, intensive care stations and treatment rooms is crucial. Therefore, it took surgical precision and steady hands to retrofit a two-meter impeller at a hospital in Ulm.

Efficient cooling towers for better battery building

LG Energy Solution is located in South Korea, and some of the cooling towers inside have been in use for many years. ebm‑papst retrofitted the battery manufacturer's factory with modern EC fans to deliver fresh air to the plant.
