IDEA® DEFROSTING SYSTEM
“Patented” defrosting system with dynamic reading of working parameters. Thanks to proprietary software it senses the real
presence of brine on the coil starting defrosting cycles only in that situation. This brings a remarkable energy saving (more than 20-
30% on the average) and a higher working continuity compared with
traditional systems.

WORKING LIMITS IN COOLING MODE
Evaporator chilled water outlet temperature: -10÷15°C Ambient temperature: -12÷18°C

WORKING LIMITS IN HEATING MODE
Condenser hot water outlet temperature: 30÷60°C Ambient temperature: -10÷35°C
 

MAIN BENEFITS
Defrosting dynamics control system IDEA®.
Availability of pumping groups.
Availability of kit for the reduction of the noise.
EC fans for a higher efficiency.
Easily of maintenance.

ELECTRONIC EXPANSION VALVE
The electronic expansion valves are synonymous of an higher energy efficiency and stability of the system.
 

 
WORKING LOGIC

TRILOGY BI
The production of sanitary hot water is made through partial or total heat reclaim systems and it matches the normal production of chilled or hot  water according to the following schemes. In working condition 2 the system produces simultaneously chilled water and domestic hot water. In working condition no. 4 (simultaneous request of hot water for heating and domestic hot water) the system gives priority to the domestic hot water production. Only when the domestic hot water request is satisfied, the system will start producing hot water for heating.

AIR/GAS HEAT EXCHANGER
Heat exchanger coil with internally corrugated copper tubes and 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.
Particular circulation on refrigerant side, in order to optimize performance in heat pump mode.
Ambient temperature sensor
Frame in galvanized steel.
 

FANS SECTION
Axial fans with sickle-shaped blades, fan guard and optimized for low noise levels.
Brushless type synchronous EC motors 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 0÷10V proportional signal coming from the microprocessor control system.
IP54 enclosure class.
