Recuperation provides partial return of energy or material which are used during the technologic process. These material and energy are reused at the same process. One of the most advantages of recuperators use is electric energy saving. Despite its high price, the use of recuperator is paid off very quickly.

Heat recuperation is a heat exchange process, during of which the heat from the exhaust air is taken . Recuperation is used with special exhaust and conditioning units, where the recuperation heat exchanger must be installed. The operational concept of recuperation in heat exchanger: supply and exhaust air are completely separated from each other in order to avoid the mixing.

There are following types of units VBW Engineering of recuperation systems with recirculation:

  • Supply and exhaust ventilation units for air conditioning systems of OKEANOS type.
  • Supply and exhaust ventilation units for air conditioning systems of OLIMP type
  • Supply and exhaust ventilation units for air conditioning systems BS type
  • Supply and exhaust ventilation units for air conditioning systems of BO type
  • Supply and exhaust ventilation units for air conditioning systems of SPS type
  • Supply and exhaust ventilation units for air conditioning systems of BD type
