N ° 1 2 battery plant pipes. 
Batteries tested at a pressure of 30 bar, suitable for operation with water up to a maximum pressure of 15 bar.

The batteries are suitable for operation with hot water (pellet boiler), low temperature water (heat pump, radiant panels, condensing boiler, etc.), cold water (chiller and / or industrial processes), water added with glycol .
Sizes with 4-row coil (4R), normally used for cooling with treatment of all (or partial) external renewal air, in cases where a high dehumidification action is required.

Electronic Brushless centrifugal fan
Each single motorization consists of a single fan directly coupled to its own motor: Centrifugal double inlet fan with aluminum impeller (with forward curved blades). Statically and dynamically balanced fan. Large diameter fans (= high air flow rates and high static pressures) with low rpm (= low noise).

Brushless motor: latest generation electronic motor with permanent magnets, brushless, direct current. IP42, Class B, electric cables protected with double insulation. Mounting on elastic supports and shock absorbers.

The 0-100% continuous variation of the air flow and consequently of the heating and cooling capacity, adapting them, instant by instant, to the actual needs of the room to be air conditioned, translates into:

• 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 electricity savings compared to a traditional 3-speed system (up to 70% in operation at the lowest rotation speeds).
• 50% indirect reduction of emissions CO2 (a result of lower electricity consumption);
• 50% reduction in noise level. Silence is ensured by the continuous variation of the air flow, which allows the unit to operate at lower speeds. 
The Brushless motor ensures maximum energy savings compared to all other technologies currently available. The Brushless complies with the Eup-ErP 2015 energy efficiency standards.

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:
the continuous variation of the air flow allows the unit to operate at lower 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 ceiling convector to which all the components (plenum, ducts, vents, etc.) for air distribution and diffusion are added. The air distribution network is easily created with circular ducts all of the same diameter so that the design of expensive ducts is no longer necessary.

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 plant engineering system: from the convector, to the ventilation ducts, to the air inlet and return 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, up to 9 outlets are available for the air ducts. All the channels are characterized by the same flow rate and very low pressure drops, making the system automatically balanced. If necessary, it is possible to intervene on the calibration dampers with which all the vents are equipped.

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

• 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 sqm apartment. Semi-rigid fan and ducts housed in a technical false ceiling. Ceiling shot under the car. The thermal requirement of the building is 9500 W corresponding to approximately 85 W / m2. From the consultation of the data in table 12 (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 an apartment of 110 square meters. Semi-rigid fan and ducts housed in a technical false ceiling. Ceiling shot under the car. The refrigeration requirement of the building is 6300 W corresponding to approximately 70 W / m2 excluding the bathrooms that are not treated. From the consultation of the data in table 12 (look at the iris pack technical sheet) it can be seen that this need is satisfied with sizing at medium speed and water delivery temperature of 10 ° C. In this case it is sufficient to use only 7 connections to treat all environments.
