STEGO
Mechanical hygrostat - KFR 012
KFR
This mechanical hygrostat KFR 012 is preset at 65 % or 50 %. This makes it easier to install hygrostats. It can often be difficult to know which humidity is to be set on the hygrostat. If the hygrostat is set at a value that is too low, the heating fan runs too frequently and thus produces large energy losses, or if the hygrostat is set at a value that is too high, components in the cabinet can be damaged. For the sake of simplicity, STEGO has developed two different models.
65 % humidity (rF) – for most cabinets with normal humidity
50 % humidity (rF) – for cabinets with components that are sensitive to high humidity.
- Preset for humidity (65 % rF or 50 % rF)
- Compact
- High breaking capacity
- Simple mounting and quick installation
