Coral
Compact air handling unit for efficient ventilation, heating and dehumidification in indoor swimming pools and wellness areas
Ventilation, dehumidification and heating in one compact unit
Compact dimensions for installation in limited spaces
Integrated Siemens control system
Counterflow heat recovery with efficiencies up to 80%
Optional inverter-controlled heat pump with low-GWP refrigerant
Corrosion-resistant design for swimming pool environments
Highest indoor air quality
Swimming pool environments require precise air treatment. Coral continuously removes humidity and airborne pollutants while supplying fresh air to ensure a healthy, comfortable indoor climate.
Hygiene
As water evaporates, airborne by-products from water treatment can accumulate in the air. Coral ensures these pollutants are reliably removed while supplying the required amount of fresh air.
Comfort
Stable temperature and humidity levels are essential for creating a pleasant swimming environment. Coral maintains optimal comfort conditions while effectively controlling humidity.
Building protection
Intelligent air distribution and humidity control help prevent condensation, corrosion and structural damage, ensuring the long-term protection of the building fabric.
)
Complete climate control for indoor pools
Coral is a compact pool air handling unit developed for small to medium-sized indoor swimming pools and wellness areas. The system combines ventilation, dehumidification and heating in a single unit, ensuring a healthy indoor climate, reliable building protection and maximum comfort.
Technology designed for private wellness environments
Every component carefully thought out
Coral combines decades of swimming pool expertise with a modern, compact design. The system continuously controls humidity, temperature and fresh air supply to create optimal conditions for both people and buildings. At the same time, intelligent heat recovery minimises energy consumption and operating costs.

Counterflow heat exchanger
Manufactured from corrosion-resistant polystyrene and specifically designed for swimming pool applications. High heat recovery efficiency and long-term reliability ensure sustainable operation.
Energy-efficient EC fans
Modern fan technology provides quiet operation while reducing electrical energy consumption.
Modular design
The two-section concept simplifies transportation and installation, even in buildings with limited access.
Optional heat pump
Using low-GWP refrigerant R-454C, the integrated heat pump delivers efficient heating and dehumidification while meeting future environmental requirements.
Integrated Siemens control system
The integrated control system automatically manages all operating modes and can be connected to all common building management systems.
Three solutions for different project requirements
Sound, efficiency and size
Three central design aspects were prioritized during the development of the new system: sound levels, energy efficiency and system size.
These factors are critical for both the planning and the operation of modern indoor pool ventilation systems.
