100% Heat and Cooling Recovery in Industrial Ventilation Systems
Environmental technology specialist Rabmer is helping E+E Elektronik reduce itsCO2 emissions by 377 metric tons per year
With the implementation of an innovative heat and cold recovery system in the ventilation system of sensor manufacturer E+E Elektronik GmbH, Rabmer GreenTech GmbH—part of the Upper Austria-based Rabmer Group—has successfully completed another project in the field of environmental technology. The innovative upgrade of the ventilation system in Engerwitzdorf (Upper Austria) has resulted in a 40% reduction in energy consumption. This is equivalent to the annual energy consumption of 500 households. The project serves as a model for other companies seeking to reduce operating costs while making a significant contribution to climate protection.
Altenberg near Linz, December 3, 2020 “There is enormous energy potential in the area of heat and cold recovery in air-conditioning and ventilation systems. “Based on the innovative APESS technology, we help companies effectively combine economic and environmental interests,” explains Ulrike Rabmer-Koller, CEO of the Rabmer Group. Due to the attractive—and rapid—payback period, we are receiving an increasing number of inquiries about this technology.”
Heat and cold are valuable resources
The project at E+E Elektronik clearly demonstrates how this innovative technology can also be applied to existing systems. At the heart of the project is the APESS system, which enables 100 percent heat and cooling recovery from exhaust air. Rabmer supported E+E Elektronik throughout the entire process, from the initial concept through the feasibility study to project implementation. Despite the challenges posed by the first COVID lockdown, the client accepted the project within the specified timeframe on July 15, 2020. “The stated goal was to reduce the ventilation system’s energy consumption by 30 percent. As a partner for innovative climate protection solutions, we are very proud that we were even able to exceed this target, achieving a 40 percent reduction,” emphasizes Rabmer-Koller.
The energy savings of 1.5 million kWh achieved at E+E are equivalent to the energy consumption of 500 Austrian households. This not only reduces operating costs but also helps the environment by cuttingCO2 emissions by more than 300 metric tons per year. These impressive figures have also won over E+E Elektronik:“We’ve been working for quite some time on optimizing the ventilation system in our cleanroom production facility. No other provider was able to guarantee us such savings. We are very satisfied and pleased with the significant cost savings, the enormous improvement in energy efficiency, and the resulting reduction in CO2 emissions,” says Wolfgang Timelthaler, CEO of E+E Elektronik.
Relevant to Various Industries
The applications of this technology, which plays a key role in achieving climate goals, are diverse. Its use ranges from the recovery of cooling and heating in office buildings and manufacturing facilities to hospitals and healthcare facilities, as well as shopping centers, hotels, and event venues.
