Clivet has introduced its SPINCHILLER3 MF, designed for simultaneous production of chilled and hot water
SPINchiller3 MF is available with a cooling capacity from 259 to 650kW, a COP up to 3.6 in heating mode and global efficiency in simultaneous use up to 7.8.
It also features a double refrigerant circuit with scroll compressors series connected on each single circuit, condensing temperature control with modulated fan speed, electronic expansion valve and high efficiency plate heat exchangers.
Axitop fan flow diffusers are said to reduce the fan power input by 3 per cent and the noise level by 3 dB(A).
The unit also has a high seasonal efficiency, placing it in the Eurovent energy efficiency “A class” (in heating mode).
The units are available in two different configurations: SPINchiller3 WSAN-XSC3 MF 2T for 2 pipe systems with total condensing heat recovery and SPINchiller3 WSAN-XSC3 MF 4T for 4 pipe systems.
Operative range is extended up to +48 deg C outdoor air temperature at partial load and down to -15 deg C in heating mode thanks to the optional device for low outdoor temperatures. It produces hot water up to 55 deg C.
The units can integrate itself with many available options, including HYDROPACK pumping sets, buffer tanks for systems with low water content and can also be supplied in primary circuit arrangement, simplifying plant installation.
