Temperature
Operation on (clean) water:
Fluid temperature and ambient temperature:
3 °C – 50 °C.
Operation on water containing antifreexe:
Fluid temperature and ambient temperature:
-30 °C – 50 °C
1).
Storage temperature:
-40 °C – 70 °C
provided that the valve is drained of uid and
stored "plugged".
Antifreeze protection
1)
If a system requires antifreeze protection, Danfoss
recommends Dowcall N or Chillsafe mono propylene glycol from the Dow Chemical Company and
Arco Chemical Company, respectively.
Both antifreezes are biologically degradable and
must be used together with demineralized water.
Mixing ratio must be:
• Min. 30% antifreeze and 70% demineralize
water providing frost protection to -13 °C
and preventing biolm in the system.
• Max. 50% antifreeze and 50% demineralize
water due to increased viscosity, providin
frost protection to -30 °C.
