Low temperature, few impurities, low hardness; disinfectants and scale removers are added
It depends on the specific project – whether it is a closed-loop or an open-loop system. There are usually requirements regarding water quality, as well as inlet and outlet temperatures and pressures. Typically, the inlet temperature is 30°C and the pressure is 0.45 MPaG, while the outlet temperature is 40°C and the pressure is 0.25 MPaG.
The pH value should be between 6.5 and 8.0
Generally, the main water quality parameters for circulating water include the following: calcium hardness, turbidity, alkalinity, heterotrophic bacteria, and microbial sludge
It must be kept clean and free of impurities; materials with high hardness also need to be softened.
It remains unaffected at operating temperatures of 80°C to 105°C; it must have properties that prevent freezing, rusting, and the accumulation of scale
Oil-free, sterile, low-salt, at appropriate temperature
