DESCRIPTION
Casing
Double-wall construction. Pre-lacquered removable grey RAL 7035 panel: - external pre-lacquered sheet, thickness 1.0 mm - class M0 glass wool, thickness 25 mm - internal galvanised sheet, thickness 0.8 mm 230 V single-phase electric motor with EC motor, 4 poles, class F. Air flow detected by an analogue pressure sensor.
Internal unit electrical cabinet
Power, control and regulation cabinet including: Transformer option for 400 V/50 Hz three-phase supply + E (without neutral). 400 V/50 Hz three-phase supply + E + N Main cut-off (emergency stop type) on front panel. 400 V / 3-Ph / 24 V transformer with protection. Protection and control for fan motor, and depending on options for humidifier and electric heater. CIAT μAir CONNECT2. Dry temperature of return air tested. Return humidity control: - Humidity control during auxiliary operation (optional) - Humidity control during dehumidification (optional) Water leak detection (standard), fire thermostat and supply air limit monitoring (options). Remote control and fault summary contact. Optional condensate pump.
Filtration
F2SI filter cells, 90% efficiency according to ASHRAE gravimetric test (G4). Optional F7 opacimetric filter. Optional dual filtration (G4 + F7) (Except DXA 5/8/10 et CW 5/8/12). Filter cells held in compression on a counter-frame with a seal to prevent all leaks. Blockage level monitored by an analogue pressure sensor.
Cold coil section
Coil copper pipes and aluminium fins. Condensates drain pan. CW model with 2- or 4-way control valve fitted and connected. Heat-insulated connection hoses available as an option. Model DXA with thermostatic expansion valve.
Ventilation section
Direct drive centrifugal fan, associated with an electronically commutated (EC motor). EC motor: fan adaptation via manual adjustment or «selfregulating» adjustment by the controller, depending on the room load - system air control. 435
