Electa-REK UTR 20-30 - UTRR 15/45 - 1

UTR 20-30 - UTRR 15/45 Air flow rate: 200 ÷ 300 - 150/450 m³/h √ Extremely thin: only 26 cm high for ceiling installation. √ Integrated air quality and humidity sensor. √ Very high efficiency filters in class ePM1 80%. √ High efficiency passive recovery unit >90%, in sensitive or enthalpy version. √ BLDC horizontal rotary compressor and constant-flow EC fan. √ Touch control as standard Fresh air terminal units with heat pump active thermodynamic recovery and opposing flow passive recovery. Construction features • Recovery unit: - First stage of heat recovery of static air-air type, sensitive or enthalpy, with opposing flows in very high efficiency polypropylene. - Second stage of heat pump active thermodynamic heat recovery (with R410A gas) consisting of high efficiency BLDC horizontal rotary hermetic compressor, evaporating and condensing coils with copper pipes and aluminium fins, electronic expansion valve and safety devices, 4-way valve for cycle inversion and dryer filter. • Fans: UTR double-intake centrifugal fans with constant flow EC motor for fresh and expelled air; UTRR: EC radial fans with constant flow for fresh and expelled air, centrifugal fans with double-intake, with EC motor, for recirculation air. • Filtering section: 80% ePM1 filters with low pressure drop air side renewal and ambient inlet, both removable at the bottom; 70% coarse filters on the recirculation side removable at the bottom, for UTRR. • Self-supporting structure, double side sandwich panelling, internally galvanised sheet steel and externally painted (RAL 9003), with high density polystyrene insulation (20 mm thick). Circular inlets (Ø 200 mm) with sealing gasket for connection to the air ducts; lower condensate collection tank with double drain. • Electrical adjustment and power panel integrated on the unit; electronic microprocessor control for fan speed management, temperature display, timed dirty filter management, air quality sensor management with flow modulation, humidity sensor management for dehumidification mode, summer/winter changeover and defrosting cycles. Version • UTR-S - Fresh air units with heat pump active thermodynamic recovery and opposing flow passive sensitive heat recovery. • UTR-X - Fresh air terminal units with heat pump active thermodynamic recovery and opposing flow passive enthalpic heat recovery. • UTRR-S - Fresh/recirculation air units with heat pump active thermodynamic recovery and opposing flow passive sensitive heat recovery, with integrated bypass. • UTRR-X - Fresh/recirculation air units with heat pump active thermodynamic recovery and opposing flow passive enthalpic heat recovery, with integrated bypass. Controls supplied separately: MANDATORY One of the following controls is MANDATORY to operate the unit: • KPUTB - Wall-mounted touch control panel, glossy black, to adjust room temperature, ON/OFF, summer/winter, Auto, Night, MIN, MAX speed, alarm signalling, with Wifi board, RS485 Modbus RTU interface and connection cable, up to 15 m from the unit. • KPUTW - Wall-mounted touch control panel, pearl white, to adjust room temperature, ON/OFF, summer/winter, Auto, Night, MIN, MAX speed, alarm signalling, with Wifi board, RS485 Modbus RTU interface and connectio
