SHEEN EVO 2.0 (WiSAN-YSE1) is the new air cooled reversible heat pump for outdoor installation, with R32 refrigerant, equipped with inverter rotary/scroll compressors and inverter fans.

The WiSAN-YSE1 range from 24,1 to 94,2 kW, is the ideal solution to meet different kind of applications thanks to full inverter technology and wide operating envelope.

It’s available in two different energy versions:

• EXCELLENCE version, with outstanding efficiency levels both in cooling and heating (SCOP up to 4,54 and SEER up to 4,81), able to provide high leaving water temperature and suitable for colder climate thanks to the wide operating range, keeping a quieter operation. 
• PREMIUM version, most effective and valuable solution both in terms of capital investment and running cost thanks to competitive efficiency (SCOP up to 4,29 and SEER up to 4,50) and enhanced delivered capacity by each size compared with the previous SHEEN EVO range.

Further strengths 

Eco-friendly solution

The use of R32 refrigerant, with a low GWP (Global Warming Potential = 675), guarantees an environmental impact that is about -70% compared to traditional R-410A refrigerant (GWP = 2088).

Advanced technology

Inverter rotary/scroll compressors, high efficiency DC fans with variable speed control, Copper aluminum coils with hydrophilic treatment as standard, are some of the technologies available that allow to:

• 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
• Ensure negligible start-up current 

Low noise operation 

The SHEEN EVO 2.0 range offers 2 different acoustic levels, without changing the unit dimensions:

• Acoustic configuration with compressor soundproofing (SC): basic version
• Super-silenced acoustic configuration (EN): from -3 to -6 dB (A) less compared to SC version

The night mode is also available, for a further reduction of the unit noise emissions by 3dB(A) compared to the super-silent version.

The capacity range for standard and super-silent configurations varies according also to the 2 selectable energy versions:

EXCELLENCE Version:

• Acoustic configuration with compressor soundproofing (SC): Range 24,1 - 80,2 kW
• Super-silenced acoustic configuration (EN): Range 19,9 - 65,3 kW

PREMIUM Version:

• Acoustic configuration with compressor soundproofing (SC): Range 25,2 - 94,2 kW
• Super-silenced acoustic configuration (EN): Range 22,1 - 75,7 kW

Maximum adaptability

The capacity modulation from 100% to 30% and  the extended operating limits that guarantee the operation all year round, are able to satisfy the requirement of multiple operating conditions.

Extended operating limits

Due to dedicated design which has as main target optimized heating performances, the new SHEEN EVO 2.0 EXCELLENCE is able to guarantee:

• Leaving water temperature up to 60°C from -4°C to 30°C ambient;
• Leaving water temperature up to 55°C from -10°C to 30°C ambient;
• Leaving water temperature up to 53°C down to -15°C ambient;
• Operating down to -20°C ambient with leaving water temperature up to 45°C.

The PREMIUM version keeps instead the same, already competitive, envelope of the current SHEEN EVO.

Many options and accessories are available:

• Hydropack with 1 on/off pump
• Hydropack with 1 inverter pump
• Storage tank 
• Drain tray with electric heater
• Additional condensing coil treatment for aggressive ambients
• 3-way valve for domestic hot water production

Cascade management

SHEEN EVO 2.0 is designed to connect up to 16 units in a local network, reaching a maximum system capacity of 1500 kW.

Additional functions

Thanks to the new electrical control box, SHEEN EVO 2.0 features many additional function to better fit each specific installation requirement:

• Remote on/off
• Heat/cool (summer/winter switch)
• DHW production management
• Double set-point management
• Set-point compensation based on outdoor ambient temperature
• Auxiliary heating generator management
• Smart Grid function
• EVU lock function
• Demand limit
• Energy metering (ENEMON)
• Activation of super-silent / Night mode acoustic version (selectable on the user interface)

Hybrid version by Clivet 

The SHEEN EVO 2.0 allows the hybrid version solution in combination with an external boiler supplied by Clivet.
The hybrid heat pumps are equipped with a matching boiler which is selected in order to optimize the system operation. 
The boilers available are for Heating only (no DHW production) in three different sizes: Gas Boiler 70.2, Gas Boiler 115.2, Gas Boiler 200F.2.
