Multi-functional air-water unit, for outdoor installation, equipped with scroll compressors and axial fans for associated 4 pipe systems.
Outdoor temperature: -18°C
Max output temperature: 60°C
The four-pipe technology is considered the best energy efficient solution able to satisfy the complex needing of all those buildings where it is necessary to neutralize simultaneous opposite thermal loads. QUATTRO PROZONE, operating in total heat recovery mode, is able to satisfy the simultaneous demand of hot and cold water all over the year, simplifying the plant and reducing operating costs.
Available in two different efficiency levels:
A. STANDARD EFFICIENCY
B. HIGH EFFICIENCY
MA: Multifunctional air-cooled unit.
LN/SL: Acoustic versions.
PB/PM/PA: Hydraulic versions.
- EUROVENT Certification
- Extension of the range with Multiscroll technology up to 880 kW (only EA version)
- Conformity to new Directive ErP
- Electronic Expansion valve standard
- Standard Modbus RS485 card
- The DIGITAL DEFROST is a digital self - adaptive defrost system able to intervene only in case of formation of a consistent thickness of ice on the fins of the condensing coils.
- High energy efficiency assured by oversized heat exchange coils and high energetic performance fans.
- ECO-PROFILE Fans. Due to the innovative profile, these fans ensure high efficiency by reducing power input and sound emissions.
- The DYNAMIC LOGIC CONTROL manages the differential of the inlet water temperature in accordance to the speed variation. Thanks to the DLC the number of the compressors’ start decreases ensuring economic and energetic savings.
- The function DYNAMIC SET POINT allows to change simultaneously the set point to achieve always the conditions of best comfort and, above all, the maximum energy saving.
