This series is the ideal solution for four-pipe systems (4T configuration), meeting the simultaneous demands for hot and chilled water. Available in the Excellence energy version (EXC), it offers top-tier efficiency in all operating modes, with SEER up to 7.85 and SCOP up to 4.67. The capacity ranges from 440 to 945 kW.
Key Features and Strengths:
Eco-friendly Solution:
The use of R513A refrigerant, which has a low Global Warming Potential (GWP) of 631, significantly reduces environmental impact compared to traditional R-134a refrigerant (GWP = 1430).Inverter Screw Technology:
- The inverter dual-rotor screw compressors perfectly match the cooling load of the plant under any condition.- They allow for great staging, ensuring high efficiency and reducing operating costs.
- They also eliminate the starting current.
Low Noise Operation:
- Standard acoustic configuration (ST): produces sound levels from 97 to 101 dB(A).- Super-silenced acoustic configuration (EN): reduces noise by 18 dB(A) compared to the ST version, thanks to an integral acoustical enclosure.
Maximum Adaptability:
With capacity modulation from 100% to 20%, dual refrigerant circuits, and the ability to produce hot water up to +55°C during the summer and cold water down to +4°C, the WiDHN-KSL1 PL series can meet diverse operational requirements. Multiple options and accessories ensure it can be tailored to the specific needs of each plant.The WiDHN-KSL1 PL series meets the stringent requirements of Commission Regulation 2281:2016, effective from January 2021.
