Energy from exhaust air
Save energy with innovative heat and cold recovery!

Reduce energy consumption in ventilation systems by up to 85%!

Recover heating and cooling and thus reduce energy costs and protect the environment – we plan and implement highly efficient new systems, optimize your existing air conditioning and ventilation systems as well as heating and cooling systems and thus reduce energy consumption by up to 85%.

Use of energy from exhaust air

Warm and cold exhaust air in air conditioning and ventilation systems are an enormous energy potential, which often remains unused. Through the use of innovative heat exchangers, if necessary also in connection with heat pumps, this energy can be introduced efficiently and economically into the existing heating and cooling circuit. Accordingly, the use of exhaust air energy should also be taken into account in all new systems in order to achieve a significant reduction in energy consumption, operating costs and CO2 emissions. A win-win situation for the plant operator and the environment!

Rabmer setzt auf APESS

By using the innovative APESS system we offer our customers highly efficient solutions to reduce energy consumption by up to 85%. The following approaches are pursued:

  • System analysis and solution concept with detailed energy balance for the complete system
  • Utilisation of exhaust air heat by returning it to the heat cycle
  • Use of dehumidification cooling and return to the refrigeration cycle
  • Demand-oriented use of heat pumps for heating and cooling production
  • Use of APESS energy management system for optimised control of cooling and heating
  • Use of optimised supply/exhaust air heat exchanger systems, individually for your plant

We support you right from the start and accompany you until commissioning.

With APESS® we also simulate the energy costs (cooling, heating, humidification) of your building in advance, i.e. in the planning phase. It depicts the most varied energy courses and provides information about expected costs with above-average accuracy. A perfect basis for good investment decisions!

In which application areas are we active?

  • Hotels, dormitories, spa houses
  • Office buildings and production halls
  • Hospitals and healthcare facilities
  • Shopping centres, etc.

Our services for you:

  • We look for the best technology for your project.
  • We carry out a feasibility analysis for you and calculate the economic efficiency.
  • We take care of detailed planning, basic and detailed engineering and project implementation up to commissioning with external partners.
