ELFOEnergy Storm EVO (WSAT-YES) is the new series of air to water full DC inverter monoblock liquid chiller for external installation with microchannel coil and with the R-32 refrigerant. 

Among the first on the market with refrigerant R-32, the new series WSAT-YES with cooling capacity from 53 kW to 85 kW features a design developed for modularity, wide operating range and seasonal cooling efficiency on top of the market, which makes it the most advanced solution for medium-sized tertiary and industrial applications.

The new WSAT-YES liquid chiller series proposes the perfect solution either for applications requesting a higher eco-sustainability with the best performances or for those made challenging by the needs of maximum reliability and continuity of operation, thanks to the possibility of implementing the modular system 

New refrigerant R-32

New ELFOEnergy Storm EVO is the sustainable solution for the conditioning and domestic hot water production thanks to the ecological R-32 refrigerant, with a GWP (Global Warming Potential) of -70% compared to R410A refrigerant. Clivet is among the firsts on the markets with a R-32 monoblock solution, being at the cutting edge of technologies and at the forefront on environmental issues.

Innovative technology and top performances

Improved performances guarantee A++ class in heating in Low Temperature (35°C leaving water) and a seasonal efficiency in cooling on top of its category, with SEER values up to 4,64. 

ELFOEnergy Storm EVO can provide heating, cooling and also the domestic hot water production up to 55°C of water temperature, with an operating range from -15°C to +43°C of outdoor air temperature. 

Thanks to the full DC inverter technology applied to compressors and fans and the microchannel coil, ELFOEnergy Storm EVO (WSAT-YES) liquid chillers present top performances, in both terms of cooling seasonal efficiency and full load efficiency. The series WSAT-YES reaches SEER values up to 4,81.
ELFOEnergy Storm EVO features also wide operating ranges from -15°C up to +48°C of outdoor air temperature, with leaving water temperature at 5°C.
ELFOEnergy Storm EVO is therefore the perfect solution for both comfort and process applications.

Modular Design

ELFOEnergy Storm EVO is designed for modularity and dedicated piping connections provided for modular combination simplify the design phase and make installation faster and easier. It is possible to hydraulically connect up to 4 units in parallel and manage up to 16 units in a local network. The combinations can also take place with different capacity units. The modular system, obtained by combining several modules, preserves the strength of the single module, but multiplies the advantages: higher reliability, simplified handling and installation, quick and easy maintenance, scalability. 
 

Application versatility

ELFOEnergy Storm EVO is already available in standard configuration or with following components, integrated on board to guarantee maximum reliability and easy installation:
•    hydronic assembly with 1 inverter pump;
•    system storage tank of 170 (size 18.2-20.2) or 275 litres (size 25.2-30.2-35.2).
 

ELFOEnergy Storm EVO represents the latest step in establishing the new range of R-32 hydronic products: it started with ELFOEnergy Edge EVO (already available, with heating capacity from 5 to 16 kW) and it has continued with ELFOEnergy Sheen EVO (with heating capacity from 24 to 62 kW).
