• Suitable for indoor or outdoor installation.
MAIN BENEFITS
• The proprietary software foresees unit working with the lowest noise emission during the night.
• Working continuity even during black-out periods.
• Automatic restart of the unit.
• BLDC Inverter scroll compressor and EC plug-fans for a higher energy efficiency.
• Availability of electric heater.
• Choice between indoor and outdoor installation.
• Free-cooling operation with +45% of air flow compared to the mechanical cooling operation. This allows to transfer more cooling power to the air conditioned room, maximizing energy savings.
• Easily of maintenance.
SUITABLE FOR INDOOR OR OUTDOOR INSTALLATION
FREE-COOLING SYSTEM
• Proportional free-cooling system

FILTER SECTION
• Washable air filters with G4 efficiency, with cells in synthetic fibre and metallic frame (EN 779-2002).
EVAPORATING SECTION
• Heat exchanger coil with internally corrugated copper tubes and high efficiency aluminium fins, specifically developed to provide high heat transfer and lower pressure drops.
• Frame in galvanized steel.
• Condensate tray in peraluman with PVC flexible discharge pipe.
SUPPLY FANS SECTION
Power supply 48VDC from UPS
• Centrifugal fans with backward curved blade, single suction and without scroll housings (Plug-fan), directly coupled to external rotor electric motor.
- I mpeller in aluminium exempt from rust formation.
- Brushless type synchronous EC motor with integrated electronic commutated system and continuous variation of the rotation speed.
The motor rotation control is obtained with the EC system (Electronic Commutation) that manage the motor according to the signal coming from the microprocessor control.
• Temperature sensor on room air intake
• Temperature sensor on room air delivery.
• Grille on room air suction.
• Grille on room air delivery.
• System for air flow loss alarm
REFRIGERANT CIRCUIT
• Thermostatic expansion valve for models MARK 06 and MARK 09.
• Electronic expansion valve for model MARK 10 INV
• Sight glass.
• Filter dryer on liquid line.
• Pressure transducer with indication, control, protection and limit functions on high pressure.
• Pressure transducer with indication, control and protection functions on low pressure.
• Refrigerant circuit with copper tubing with anticondensate insulation of the suction line.
• R410A refrigerant charge and lubricant oil
CONDENSING COIL
• Heat exchanger coil with high efficiency aluminium fins, specifically developed to provide high heat transfer and lower pressure drops. The combination of two factors, special tubes and fins, allow to optimally combine the following aspects:
- Maximum capacity relative to the size of the exchanger.
- Minimum charge of refrigerant.
- Reduction of the air flow required for the heat exchange.
• Frame in galvanized steel.
• Grille on air suction/discharge.
CONDENSER FANS SECTION
Power supply 48VDC from UPS
• Centrifugal fans with backward curved blades, single suction and without scroll housings (Plug-fan), directly coupled to external rotor electric motor.
- I mpeller in aluminium exempt from rust formation.
- Brushless type synchronous EC motor with integrated electronic commutated system and continuous variation of the rotation speed.
The motor rotation control is obtained with the EC system (Electronic Commutation) that manage the motor according to the signal coming from the microprocessor control.
DIRECT FREE-COOLING SECTION
Power supply 48VDC from UPS
• Deviating damper on ambient air.
• Proportional servomotor directly driven by microprocessor control.
• Grille on ambient air suction.
• Temperature sensor on ambient air.
The free-cooling system does not require the installation of overpressure damper or air expulsion system, into the room.
