Sizes with 4 row coil (4R), normally used for cooling with treatment of the whole (or partial) outdoor fresh air, in cases where is required a high dehumidifying action.

Electronic Brushless centrifugal fan
Each engine consists of a single fan directly coupled to its engine: Centrifugal fan with double air inlet aluminum impeller (forward curved fins). statically and dynamically balanced fan. Extensive diameter fans (= high air flow and high static pressure) with low revolutions (= low noise level).

Brushless motor: the latest generation of electronic motor, permanent magnet, brushless, DC. IP42, Class B, electric cables protected by double insulation. Mounted on elastic and anti vibration supports.

The continuously variable 0-100% of the air flow and consequently the heating and cooling performances, adapting, instant by instant, to meet the actual needs in the room, resulting in:

• Total comfort: reduced temperature fluctuations and humidity in the air-conditioned rooms;
• Mass Rapid stream of the air-conditioned environments;
• Maximum silent running

The Brushless + Inverter technology, results in:
• 50% annual savings in electricity compared to a traditional, 3-speed system (up to 70% when working at lower engine speeds).
• 50% indirect reduction of emissions CO2 (a result of lower electricity consumption);
• 50% reduction of the noise level. The silence is ensured by continuous variation of air flow, which allows the unit to operate at lower speeds.
The brushless motor provides maximum power savings compared to all other currently available technologies. The Brushless complies with energy efficiency standards ErP Eup-2015.

modulating performance:
the continuous variation 0-100% of the air flow results in the consequent modulation of heat and cooling power, adapting them, moment by moment, to meet the actual needs in the room.

Total comfort:
- Reduced fluctuations of temperature and humidity in the air-conditioned premises
- Fast working condition of the air-conditioned environments

Extremely quiet operation:
continuously variable air flow allows the unit to operate at low engine speeds, ensuring:
- Reduced noise by an average of 50
- NO annoying attaches / detaches

Lower consumption:
- 50% annual savings of electricity
- 50% reduction in emissions CO2
Significant reduction in electrical input, that when working at low engine speeds reaches 1 / 3 than that of the traditional induction motors 3
speed and integrated operation amounted to approximately 50%, with the corresponding reduction of emissions CO2.

Configurations

Iris Pack

IRIS PACK is the air conditioning system for apartments up to 150 square meters and small commercial units. In combination with a heat pump it guarantees both the heating that summer conditioning.

The heart of the system is the IRIS CN 800 horizontal false ceiling convector, to which are added all the components (plenum, channels, nozzles, etc.) for air distribution and diffusion. The air distribution network is easily created with circular ducts all of equal diameter, so that no expensive ducting is required.

Applications:

• Winter air conditioning with boilers and heat pumps
• Summer air conditioning with reversible heat pumps and coolers
• Residential and commercial applications
• Thermal and refrigeration integration in existing systems

ADVANTAGES
• Turnkey solution. IRIS PACK is a complete system of systems: from the convector, to the ventilation ducts, to the air inlet and outlet vents. The package is complete with all the components necessary for correct installation.

• Balanced system. Thanks to the air distribution plenum designed specifically for IRIS CN 800, there are available up to 9 outputs for the air ducts. All the channels are characterized by an equal flow rate and very low pressure drops, making the system automatically balanced. In case of need, it is possible to intervene on the calibration dampers with all the outlets.

• Quick and easy installation. IRIS PACK is installed quickly and easily. The air delivery ducts are connected on one side to the distribution plenum and on the other side to the intake vents. The fixing accessories that complete the system allow it to be installed properly.

• Architectural integration. IRIS CN 800 with the reduced thickness of only 275 mm is housed in the false ceiling as well as the air ducts. The plenum of recovery of the unit is of telescopic type so as to adapt itself to the height of the false ceiling. In this way the system is completely invisible. The air outlets are available in two versions, wall and ceiling, to satisfy every architectural requirement.

• Comfort and silence. All components, from the channels to the vents, have been developed to work with low air speed. This makes every room quiet and comfortable without annoying air currents.

Schemes

Examples of plant

1 SCHEME
Heating of a 110 square meter apartment. Ventilant and semi-rigid ducts housed in a technical false ceiling. Shooting on the ceiling under the car. The thermal requirement of the building is 9500 W corresponding to about 85 W / m2. From the consultation of the data in the 12 table (Iris Pack technical sheet) shows that this requirement is met with sizing at the average speed and feed temperature of 50 ° C. Depending on the environments to be served, all the front plenum outputs are used.

2 SCHEME
Conditioning of a 110 square meter apartment. Ventilant and semi-rigid ducts housed in a technical false ceiling. Shooting on the ceiling under the car. The refrigeration requirement of the building is 6300 W corresponding to about 70 W / m2 excluding bathrooms that are not treated. From the consultation of the data in the 12 table (look at the iris pack technical sheet) it is clear that this requirement is met with sizing at the average speed and water delivery temperature of 10 ° C. In this case it is sufficient to use only 7 connections to treat all the environments.
