R404a water cooled condensing unit with 8oC cooling water

[wta12]

What capacity do you need? Pure water? What are your water connections? Seems you're confusded, only a water regulating valve like WVFX. See it as a proportional control of speed on condensor fans.

As shown, i need est 6 kw come along with pure water (softened chilled water). Will this valve be help at the start-up stage, when we can help low condensing pressure condition ?
@all : i still have question about 0 oC or less suction gas temperature with r404a and piston compressor. Normally suction gas temp at 20 oC as standard. What problem will come when we have lower than standard suction gas temp ?
