Say hello to carbon-neutral cooling and heating.
We build the most efficient heating, cooling and heat recovery systems.
Together, we can change the world. And APESS® definitely has a role to play.
Save resources and be sustainable.
- Reduce CO2 emissions by up to 85%
- Conserve resources with highly efficient heat pumps
- 100% independence from gas and oil
- Small amounts of refrigerant—longstanding compliance with the EU F-Gas Regulation No 517/2014
- Use of natural refrigerants (NH3, CO2, propane) possible
- Use of existing components possible
Wherever air needs to be conditioned.
- Fast, comprehensive system design with based on minimal information
- Carbon-neutral energy bills.
- Compatible with all ventilation units
- Low-noise operation
- Can be installed in historic buildings
- Perfect for new buildings and renovations which use existing components
- Fully transparent display
- Funding documents
- Comparisons with other systems possible
- Maximum support for planners from our team
Knowledge, experience and innovation. That’s what defines APESS®.
- Perfect configuration of system components and calculation of all thermodynamic processes as well as their optimisation in advance
- Brilliant logic: full use of exhaust air energy through two-stage heat recovery
- 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
In office complexes, shopping centres, hospitals, hotels, swimming pools and all kinds of commercial and industrial buildings (e.g.: clean rooms, production facilities, etc.)
successful APESS® installations
of carbon emissions saved every year
Not a new invention. And yet ingeniously innovative.
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 %.
APESS® innovations are measurable.
Intelligent systems save time and create safety.
Our software presents complex solutions with maximum transparency and makes every project 100% traceable. The path to APESS® is simple: Only a few key data are necessary to receive a comprehensive system proposal including exact energy costs and CO2 emissions within a few days.
- High planning reliability
- Guaranteed to be the most efficient solution
- Enormous time saving
- Permanent support in the planning and implementation process
Survey phase
Transmission of the technical design data of the full air-conditioning units, heating and cooling load as well as the design schemes
Design planning
Developing a design plan with the help of the APESS® software, which at the same time also indicates the energy consumption and savings potential that can be expected upon realisation.
Optimisation phase
Improvements or consideration of special customer requirements such as the use of natural refrigerants or free cooling and simulation of the optimised system.
Tendering phase
The planner receives all documents, including calculated data, HX diagrams and information, in order to be able to make the tender. All documents for funding applications are also included here.
