Tender Specification SysFreeCool Tender Specification SERIES: SysFreeCool TYPE: Free-cool ing module CAPACITY RANGE: Cool ing capacity from 100 to 550 [kW]
Tender Specification SysFreeCool 1 General description Free cooling option is available in two versions: • Slave: the module can be linked to a unit of the SyScroll range with structural and hydronic links.
Tender Specification SysFreeCool 2 Key points Main advantages of free-cooling module if compared to the standard integrated free-cooling solution are: • Flexibility: thanks to the fact that the module is physically independent from the unit it is possible to choose the best size matching, according required free-cooling capacity and sound level • Fan deck independency: there is no need to find a compromise between chiller and free-cooling fan deck management.
