Configuration

  • Vertical air supply, M01 assembly (default horizontal supply, M00 assembly)
  • In the STD version : different configurations of available pressure from 7 to 35 mm.w.c. configuration
  • Vertical air supply, M01 assembly (default horizontal supply, M00 assembly)
  • In the STD version : different configurations of available pressure from 7 to 35 mm.w.c.

Climatic conditions

  • In units with the STD version that work in cooling with an outdoor temperature lower than 12°C, the condensation pressure control allowing an "all seasons" operation (up to -15°C) is mandatory. This is performed per motorized damper in the fan outlet.
  • Coils protection : 
    • Coil with copper pipes and copper fins (upon request)
    • Coil with copper pipes and aluminum fins with polyurethane and blygold coating
  • During periods with low outdoor temperatures, anti-freeze protection for the unit :
    • Electrical heaters in the condensate drain pan. Mandatory when outdoor temperatures are below 3°C
    • Operation with glycol water up to a minimum outlet temperature of -7°C
    • Anti-freeze protection with flexible electrical heaters around the pipe of the hydraulic circuit

Installation

  • Antivibration mounts made of rubber
  • Protection grille for the coil
  • Gravimetric filters in the return air. The filters frame is removable, and upon request, it is possible to supply the frame independently with the unit, to be joined on site
  • Flexible ducts for supply and return air
  • Flexible hydraulic connections (500mm), supplied in the kit
Available for:
  • Inlet / outlet of the unit
  • Inlet / outlet of the desuperheater circuit
  • For 30PA units, filter with stainless steel mesh (500 microns), supplied in the kit
