The liquid temperature should not exceed 80 °C without the conveyed cooling fan and 150 °C cooling. For higher temperatures, it is necessary to change the structure of the fan. ErP : These fans are within the scope of Directive 2009/125 / EC. This law does not apply in the following cases:
- Operation in potentially explosive atmospheres (ATEX)
- Operation at high temperatures (fans designed with cooling fan)
- Operation at temperatures below -40 °C
- Working in toxic, corrosive or corrosive environments (use of materials such as AISI 304, AISI 316, manganese steels).
These series are centrifugal forward curved fans and therefore Ntarget = 42 is expected (Reg. UE N.327 / 2011).
Efficiency IE2 motors in accordance with IEC 60034-30 are taken into account in ErP calculations.
