Planning and assembly instructions

  • Duct device for the installation in the technical room - No disruptive devices in the swimming pool
  • 5 sizes from 700 to 4000 m³/h
  • Different air routing variants permitting a simple duct routing
  • Thermally decoupled housing
  • Extensive functional and equipment features
  • Good indoor climate in the pool thanks to constant admixture of outside air
  • Problem-free introduction thanks to the modular structure
  • No cooling circuit - therefore easy to maintain and service
  • Low energy consumption
  • Simple heating connection through compact control station
  • Broad range of accessories
  • Coordinated air duct system
  • Constant power adjustment by means of energy-saving, stepless EC direct current motors
  • Additional savings and noise reduction through demand-dependent, stepless operation
  • Better efficiency of energy recovery with reduced air volume
  • Comparison between the supply and exhaust air volume can be carried out very precisely (vacuum setting)

Touch panel control equipped with a colour display of 4.3 inch

  • Simple menu-driven operation
  • Integrated web server
  • Logging of alarms and any system data (actual values etc.)
  • Comprehensive software options through simple configuration
  • Switching between useful and eco mode through the internal timer or remote control
  • Outside temperature dependent humidity shift
  • Min. and max.limitation of the supply air temperature
  • Various bus interfaces

Equipment list

The device consists of 2 housing parts

Part 1 (basic module)
equipped with supply air fan, exhaust air fan, mixed air chamber, PWW heating register, supply air filter, and control cabinet equipped with a control unit.
Part 2 (WRG module)
with heat exchanger for energy recovery, condensate collecting tray, droplet separator, exhaust air filter

Housing
Stable, corrosion-resistant profile frame construction made of aluminium hollow chamber profiles, powder-coated. The profiles are thermally decoupled by means of integrated plastic webs, so that the heat transfer between the device chambers and the environment can be reduced to a minimum level. Cladding panels equipped with highly insulating Hydrotec foam core. Circumferential base.
Supply/extract air fan
equipped with energy-saving, stepless EC direct current motors.
Mixing chamber
as an outside air/circulating air mixing chamber with two louvre flaps opening in opposite directions.
Air heater
Pull-out heat exchanger for hot water operation.
Supply air/extract air filter
Slide-in frame equipped with a Z line filter. Filter cell with pleated filter medium, fully incinerable and metal-free.
Energy recovery
Pull-out plate heat exchanger for the heat recovery of the sensible and latent heat energy contained in the air flows.
Coated stainless steel condensate pan equipped with a side drainage connector.
Control cabinet and control unit
integrated in the device with all modules for all tasks in the fields of control and monitoring.
Control package equipped with a touch panel control UNICON C, a colour display of 4.3 inch, and integrated in the control console.
Various interfaces (Ethernet TCP/IP, CAN, OPC, RS484, RS232) enable the connection to building management as well as third-party systems. Thanks to the optionally integrated web server, the operation or data transfer can take place through the internet as well. Various software options.
