Latest generation X-POOL+ dehumidifiers

Specially designed for ventilating, heating, air-conditioning and dehumidifying all types of premises with a high level of humidity, such as swimming pools, spas, rehabilitation centres, fitness centres and certain industrial processes.



Thermodynamic dual-flow dehumidification system

The X-POOL+ thermodynamic dual-flow dehumidification system is designed to meet all the air treatment needs of small to medium-sized pools (hotels, spas, balneotherapy centres, physiotherapy centres, retirement homes, campsites, etc.)
Thanks to the various innovations and materials used, X-POOL+ combines performance, reliability, air quality, and respect for the environnement.

Various operating modes are available :

Dehumidification is provided by the action of the heat pump’s refrigeration cycle combined with a plate heat exchanger (recuperator).

The dehumidifier operates with adaptive control :

For temperate climates :

> When the building is unoccupied, the control system favours thermodynamic recycling and will start a dechlorination cycle one hour before the building is open to the public.
> When the building is occupied, dehumidification will be provided by fresh air, to ensure the comfort of occupants. The thermodynamic system will then operate as a heat pump to recover heat from the air or water.

The ETT packaged unit consists of 3 compartments :

  1. A technical compartment containing the refrigeration components, the electrical board and the control units.
  2. A supply air compartment for fresh air renewal and energy recovery.
  3. An extraction compartment for dehumidification.
