I'd agree with Dave.
One consideration, from a costs point of view, excessive water
flow means (unless you recycle your coolant, or are on your own
water supply) a higher than necessary water bill. Just a
thought......

Attila,
As long as your DP oil is not freezing and sticking to the
sides of the line, I don't think you can have it "too
cold".?
Dave
Hello,
I have (maybe a dummy ) question to the DP cooling. In
many manuals are written about what if the cooling is not
sufficient enough. But nowhere I have seen what happends
if the coolig is too eccessive. For example, the cooling
water flow is too high and the return line water is cold.
In my case the inlet temperature of the cooling water is
15 celsius, the return is max. 25 celsius, but often 21-23
celsius. I don't know the water flow , but it is surlely
more than 0.15 gpm, which is the reccondended by the
manufacturer. I read somewhere if the DP wall is too cold,
than the oil cannot flow back enough fast and that slows
the punping speed and lowers the fluid level in the pump.
So if I overcool my? DP, what happens? Slower pumping
speed, at gas load, slower pump down? and/or higher base
pressure, cannot reach the ultimate pressure of the
system?
Any comments?
Regards
Attila
