WSAN-YSC4 - WSAN-YSC4
SPINCHILLER4 HEAT PUMP
It is available the new SPINChiller4 (WSAN-YSC4) series, the new air cooled heat pump for outdoor installation, with R32 refrigerant, and Multiscroll technology.
WSAN-YSC4 series is available with two energy versions Excellence (EXC) and Premium (PRM), with a capacity range from 215 up to 655 kW.
The Excellence (EXC) version is distinguished by its very high seasonal efficiency, offering SEER values up to 4.89.
The Premium (PRM) version offers high seasonal efficiency values, SEER up to 4.66.
Low environmental impact solution
The use of R32 refrigerant, with a low GWP (Global Warming Potential = 675), guarantees an environmental impact that is one third compared to traditional R-410A refrigerant (GWP = 2088).
Multiscroll tecnology, High efficiency EC fans with continuous speed regulation, are some of the technologies available on Spinchiller4 which offers:
- Perfectly match the cooling load of the plant in any condition
- Follow the load also with a great staging
- Ensure high efficiency values, reducing operating costs
Low noise operation
The WSAN-YSC4 series offers 3 acoustic levels, without changing the unit dimensions:
- Standard acoustic configuration (ST): basic version
- Acoustic configuration with compressor soundproofing (SC): -4/-5 db (A) compared to ST
- Super-silenced acoustic configuration (EN): -7/-8 dB (A) compared to ST
Up to 8 regulation capacity steps, an hot water production up to +55°C and a wide operating range in heating down to -15°C of external air temperature, are able to satisfy the requirement of multiple operating conditions.
Many options and accessories are available to suit the needs of each plant (such as: integrated hydronic assemblies, partial heat recovery, storage tank).
Plate or shell and tube exchanger
The WSAN-YSC4 series offers the possibility to choose the type of the user side heat exchanger: Plate heat exchanger (standard choice), or Shell and tube heat exchanger.
This new solution is recommended for all applications where the fluid has impurities.
Defrosting smart management
The automatic defrost cycles on the remaining external exchanger surface are managed in alternated mode for each refrigerant circuit, guaranteeing the 50% of the capacity.
Already complies with 2021 requirements
WSAN-YSC4 is conforming today with the 2021 stricter requirements of the Commission Regulation 2281:2016, with both energy versions Excellence and Premium.
Perfect for LEED
All Excellence models satisfy prerequisites 2 and 3 of Energy and Environment thematic area. Furthermore, they match the parameters of Credit 4 that allows to achieve 2 points (Leed 2009). The correlated data are included in the technical bulletin.
Availability for sale
The Spinchiller4 series is available immediately.
Sizes 225.6 and 240.6 (both Excellence and Premium versions) are not currently available and will be made available later this year.
