WORKING CNDITIONS:
1.Liquid temp.:-10°C to +100°C;
2.Ambient temp.:+40 °C;
3.Medium requirement: clean without sundris, mineral oil, stickiness and corrosiveness;
4.Suitable Fluids:
Heating water to VD 12035
Heatina water
Water and ethanol maximum ratio : 1:1
5. Maximum operating pressure : 10bar ;
6. Minimum inlet pressure:
