I have to reduce the evaporation rate of a water-glycol fluid (oughto safe 620). The fluid is inside a tank, about 150 Litres capacity, that cannot be pressurized, the level of the fluid can change from 50 to 100 cm. The temperature range is 15-50°C. The solution shuld be the cheapest.
Can you...
I don't know the optimum for CITGO Glycol FR-40XD but for Oughto SAFE 620 46 cSt the maximum is 50 °C. if the temperature goes over the movement of the elevator is still OK but the evaporation rate is not acceptable .
I'm still looking for some good idea to reduce the evaporation rate or to...
