Clivent introduses SPINchiller4 (WSAT-YSC4) series, the new air cooled liquid chiller for outdoor installation with R32 refrigerant and Multiscroll technology.
WSAT-YSC4 series is available with two energy versions Excellence (EXC) and Premium (PRM), with a capacity range from 720 up to 939 kW.
The Excellence (EXC) version is distinguished by its very high seasonal efficiency, offering SEER values of up to 5.28.
The Premium (PRM) version offers high seasonal efficiency values, SEER up to 5.03.
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).
Advanced technology
8 scroll compressors on 2 refrigeration circuits, EC fans with continuous speed regulation (Excellence version), Full aluminum micro-channel coils, 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
- Reduce the refrigerant charge by up 30% compared to traditional coils
Low noise operation
The WSAT-YSC4 series offers 3 acoustic levels, without changing the unit dimensions:
- Standard acoustic configuration (ST): basic version
- Acoustic configuration with compressor soundproofing (SC): -3 dB (A) compared to ST
- Super-silenced acoustic configuration (EN): -7 dB (A) compared to ST
Maximum adaptability
Up to 8 regulation capacity steps and wide operating range from +50°C to -18°C of external air temperature, are able to satisfy the requirement of multiple operating conditions.
Plate or shell and tube exchanger
The WSAT-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.
Hydronic assemblies
The hydronic assemblies available in the WSAT-YSC4 series are:
- 2PM: Hydropack with 2 on/off pumps (parallel operation)
- 2PMV: Hydropack with 2 inverter pumps (parallel operation)
- 1P1SB: Hydropack with 1+1 on/off pump (1 pump in stand by)
- 1P1SBV: Hydropack with 1+1 inverter pump (1 pump in stand by)
Compact Size
The space savings are an increasingly important aspect in the design of the building.
Thanks to the new layout, the WSAT-YSC4 units are among the most compact units on the Market.
Already complies with 2021 requirements
WSAT-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
Both Excellence and Premium versions 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).
