Through-the-Wall Version

DRY TTW

DRY TTW (through-the-wall) is a separate version with a different body from DRY METAL, supplied with ducts and a white fibreglass cover. The unit sits behind the wall shared with the pool hall; dry air and humid air are connected through ducts to grilles in the wall, so the unit itself is not visible in the hall.

DRY TTW main parts
  1. 1Dry air outlet
  2. 2White fibreglass cover
  3. 3Humid air intake
  4. 4Duct cut to suit the wall thickness
  5. 5Pool hall side grilles
  6. 6Control panel
  7. 7Power and condensate hose
DRY TTW main parts
  • The unit is usually placed in a plant room next to the pool hall; only the anodised intake and outlet grilles are visible in the hall.
  • If required, the unit and ducts can also be placed on the outside wall with thermal insulation.
  • The ducts are cut to suit the wall thickness.
  • To measure humidity inside the hall, a wired room controller or the wireless EASY 300 can be added.
