Double-wall construction (M0/A1 fire resistance). Detachable pre-coated grey (RAL 7035 and RAL 7024) panels. - 0.8mm painted pre-coated exterior panel. - 25 mm mineral wool insulation. - 0.8 mm galvanised interior panels.
Outdoor unit (DXA model)
CONDENCIAT CD air condensation unit. Power supply: Three-phase 400V / 50Hz + earth T. SCROLL heat compressor. HP safety pressure switch. 2-speed IP54 motor. Coil protection grille.
Filter cells: G4, F7. DXA: Filter cells tightly compressed against counterframe by a gasket to ensure a leaktight seal. CW: Holds filter cells pressed against the counter frame with the gasket directly on the filter cells. Filter restriction monitored by an analogue sensor. Restriction values displayed by controller.
Free cooling box. Support base for delivering supply air into a raised floor. Cased base with grille or damper. Supply plenum. Motorised intake damper. Fire thermostat. Supply air low-limit sensor. LON gateway. Management of pressure in raised floor (only for CW). Changeover thermostat (only for CW).
Cooling coil section
Copper tubes, aluminium fins. Aluminium or stainless steel condensate drain pan. Stainless steel coil casings (option). Fitted and connected two-way or three-way control valve.
Plug fan coupled with an induction motor or an electronically commutated (EC) motor. EC motor: fan speed adjusted by a potentiometer or automatically by the controller based on room loads (system air control). The fan* also has a ModBus card which allows faults and settings such as the actual power input, current, rotation speed, etc. to be transmitted. *CW only
Electrical power and control box consisting of: - Power supply (three phase, 400 V, earth). - Main disconnect switch. - Protected transformer (three phase, 400 V, 50 Hz). - All electrical components protected and controlled by a circuit breaker and contact switch. - CIAT μAIR CONNECT2 controller. - Monitoring of return air dry-bulb temperature. - Monitoring of return air humidity during supply or dehumidification. - Water leakage detection as standard - Remote control and fault summary contact.
