Clivet has released its new SCREWLine (WDAN-iK4 MF) series, which is a new air cooled multifunction heat pump for outdoor installation.
It uses R513A refrigerant and has inverter screw compressors.
The WDAN-iK4 MF series is the ideal solution to meet the simultaneous needs of hot and chilled water in four-pipe systems (4T configuration).
It’s available in Excellence energy version (EXC) which offers high efficiency in all operating modes: SEER up to 5.18 and SCOP up to 4.21.
The capacity range varies according to the three selectable acoustic levels:
- Acoustic configuration with compressor soundproofing (SC): Range 523 – 990 kW
- Silenced acoustic configuration (LN): Range 512 – 937 kW
- Super-silenced acoustic configuration (EN): Range 450 – 876 kW
Inverter dual-rotor screw compressors, hiigh efficiency EC fans with continuous speed regulation and copper aluminum coils with hydrophilic treatment, are some of the technologies available on SCREWLine.
It has capacity modulation from 100 to 18 per cent, a double refrigerant circuit and extended operating limits that guarantee operation all year round.
With outdoor temperatures from -10°C to +46°C and hot water production up to +60°C even during the summer season and cold water down to -8°C even in winter, it can meet the needs of any system.
The regulation of the unit in winter period optimizes the defrost cycles to satisfy the system cooling request, avoiding changes in operation and loss of efficiency.
Furthermore the hydrophilic treatment applied on the coils facilitates the drainage of water making the defrosting cycles more effective.
