Wellness and swimming pool facilities


The equal-pressure ventilation system with heat recovery ensures optimal indoor environmental quality in wellness and swimming pool facilities while controlling humidity and operating energy-efficiently.

Main features of the system:

  • central air handling unit for the whole plant
  • single pressure ventilation
  • heat recovery
  • suitable for new buildings and renovations

Basic elements of the system:

  • central air handling unit with ZZT designed for areas with increased humidity load

In an equal pressure system with ZZT, fresh air is supplied to the pool or wellness area of the facility, while at the same time the humid, dehumidified air is exhausted. In the air handling unit, heat is recovered from the exhaust air and at the same time the humidity of the indoor environment is treated. The system reduces condensation on building structures, contributes to the protection of the building and ensures high comfort for visitors and staff in an energy-efficient operation.
