Say goodbye to oil and gas
Say hello to carbon-neutral cooling and heating.
We build the most efficient heating, cooling and heat recovery systems.
What does APESS® offer?

ENERGY EFFICIENCY

Today. For tomorrow. Our energy centers and heat pump systems reduce energy costs and CO₂ emissions in buildings by up to 85% - sustainably and independently of fossil fuels.

HIGHEST PRECISION

Calculated to the point. Every APESS® energy center is based on precise thermodynamic simulations and delivers the optimum, property-specific solution for heating, cooling and recovery.

PERFORMANCE

Refurbishment or new build. APESS® configures the most efficient system architecture. Modular concepts enable economical, scalable and future-proof energy efficiency for every building.

Wir revolutionieren die Klimatechnik. Nachhaltig, mit dem Ziel Millionen Tonnen von CO2 einzusparen.
APESS® GmbH

Luftkonditionierung ist unsere Welt. Maximale Energieeffizienz, hochpräzise Systemkonfigurationen und absolute Sicherheit sind die Eckpfeiler unseres Erfolges.

Die APESS® GmbH vereint jahrelange Erfahrung, Entwicklungsarbeit und Kompetenz aus den Bereichen der Kälte- und Klimatechnik, Hydraulik- und Regelungstechnik. Mit ihren umweltschützenden Energiesystemen können Energiezentralen in bestehenden wie auch neu gebauten Objekten hoch effizient (um-)geplant und realisiert werden.

Hinter dem Namen APESS (Ambient Protecting Energy Saving Systems) stecken mehrere Verfahrenspatente, Einzelmodule sowie eine einzigartige Software, die jeweils die beste Konfiguration der Energiezentrale erlaubt und bereits im Vorfeld exakte Energieverbräuche und den Gesamtwirkungsgrad verbindlich angibt.

Gemeinsam mit unseren Partnern, Stakeholdern und Kunden sehen wir ein enormes Potential CO2 im großen Stil einzusparen, Kühlen und Heizen wirtschaftlich zu machen und einen aktiven Beitrag zum Erreichen der Klimaziele zu leisten.

AVL List GmbH

Kompromisslos nachhaltig:
Wir zeigen,
wie's ohne Öl und Gas geht.

Wir können Ihnen viel über Energieeffizienz und Einsparpotentiale erzählen. Das tun wir auch gern. Noch viel lieber zeigen wir Ihnen, welche innovativen Lösungen wir mit unseren Partnern umsetzen. Eines unserer jüngsten Projekte haben wir mit der AVL List GmbH realisiert. Die Gebäudeeffizienz im Tech Center wurde weit über den Standard hinaus maximiert und kommt ohne Öl, Gas und Fernwärme aus. Besonders Interessierte sind herzlich willkommen, die Anlage mit uns vor Ort zu besichtigen

  • An overall control concept
  • High compatibility with all heat recovery systems
  • Subsequent installation in existing systems
  • • Integration of thermal solar photovoltaic systems, as well as geothermal probes and other energy sources (e.g. server rooms)
  • Integration of other heat sources e.g. groundwater, waste heat from processes, sewerage, etc.
  • Efficiency maximisation: free cooling; cold heat displacement; adiabatic exhaust air cooling; dehumidification cold recovery, etc.
  • Constant or readjusted supply air temperature, even with variable air volume flows
  • Stepless control
  • High operational reliability

Cooling and heating do not have to cost the earth.

  • Save on operating costs by up to 80%
  • Short amortisation times—from as little as 6 months
  • No CO2 compensation costs
  • Costs for building conversions are often completely eliminated
  • Existing components can be used in renovations
  • Savings guarantee
  • Funding

OPTIMUM ENERGY CONSUMPTION.

In office complexes, shopping centres, hospitals, hotels, swimming pools and all kinds of commercial and industrial buildings (e.g.: clean rooms, production facilities, etc.)

The European Union’s requirements for energy efficiency and using renewable energies to generate heating and cooling in buildings are putting pressure on investors, operators and planners. In addition to the environmental aspect, the cost efficiency aspect is also worthy of note. APESS® elegantly brings both aspects together in its systems with unique software. Our customer reviews in the German-speaking region speak for themselves. The continuous monitoring clearly demonstrates that APESS® achieves impressive performance, thanks to its flawless coordination of all components.

"In addition to our social responsibility as an international chemical company, we also want to be a role model in terms of environmental protection and sustainability in our region. With APESS® we have not only saved an enormous amount of energy and costs, but the investment costs have also quickly paid for themselves."

DI Klaus Raunegger, MBAManaging Director MERCK KGaA & Co Spittal

"Energy saving is becoming more and more important for our customers, so with APESS® we have acquired a solution portfolio with which we can save maximum costs and CO2 in ventilation systems. We are just as enthusiastic about the results as our customers and see a lot of potential in APESS®!"

Klaus PichlerRabmer GreenTech GmbH

"APESS® has closed a real gap and created enormous added value in air conditioning technology. A heat pump alone does not make for efficient heating and cooling. Only when the entire system with all its components is configured in such a way that each individual part runs optimally can really good efficiency levels be achieved. APESS® can do this and is therefore unique on the market."

Heinz-Dieter HombücherInventor and Managing Director of air2000 GmbH

"APESS® is an ingenious invention for saving energy costs and CO2 in buildings on a large scale. It is a gift with which we can achieve the climate targets and play an active role in the energy transition."

DI Reinhard Filzmaier

Not a new invention. And yet ingeniously innovative.

100% optimized

APESS® revolutionizes energy efficiency in buildings. With intelligent software and progressive components.

The calculation and optimisation of energy flows has accompanied us for many years. The logic of APESS® fully utilises the energy potential of the exhaust air and thus achieves a heat recovery of 100 %.

This is made possible in part by the innovative manufacturing software, which in the first step designs and virtually maps the individual components such as the heat exchanger, hydraulic unit or heat pump on the basis of the specified key data. In the second step, the simulation software brings these components together and calculates or optimises all thermodynamic processes in the air conditioning and refrigeration technology over an entire year. In this sense, APESS® is a method for the optimised use of tried and tested components that have been established thousands of times on the market in ventilation and air-conditioning technology. This provides additional security and the guarantee that the energy centres implemented with APESS® work optimally – exactly as calculated – and realise enormous savings potential. To ensure that APESS® can be used to its fullest extent, a team of experienced technicians takes care of the design.
