Frame made from extruded Anticorodal 63 aluminium alloy bars, connected by 3-way reinforced nylon joints.•
Sandwich panels, 23 mm thickness, galvanized sheet metal inner skin and precoated sheet metal outer skin; 45 kg/m3 density foamed polyurethane as heat and sound insulation.
•Filtering sections at both air intakes complete with efficiency cell filters, ISO 16890 COARSE 55% (G4 EN779), extractable from both lower and side removable panels.
•Direct driven double inlet EC motor centrifugal fans with dedicated driver; constant air flow rate as standard operation (except size 35 and 60).
•First step of energy recovery (static type) by air-to-air crossflow aluminium heat exchanger; lower drain tray, estende to the whole area of heat treatment.
•Second step of energy recovery (dynamic type) by air-to-air reversible heat pump system composed of electric driven rotating compressor with BLDC motor and dedicated driver, evaporating and condensating reversible Cu/Al finned coils, electronic expansion valve, liquid receiver and separator, 4-way reversible valve, high and low pressure switches and sensors, biflow drier filter, liquid indicator.
•Built-in electric box to control power loads, NTC temperature sensors on both air circuits, electronic controller to control room temperature, heating/cooling mode, defrost cycles and timer control system; built in control panel.
•Display control and new electrical box optimized for better heat dissipation and increased accessibility for the operator; also facilitated the connection to main board for the accessories.
•Logic control specially designed for reducing electrical consum- ption and adjusting the working capacity to temperatures, humidities and the ambient crowding (option); alternative possibility for thermoregulation in function of return/ambient temperature or supply temperature fixed point.
•Modbus RTU PCB interface (optional) for supervision of the operative parameters in real time.
