Cooling purity water without a exchanger.
Cooling purity water without a exchanger.
(OP)
Dears,
I have a problem with our 20C Purity water loop, in summer the water temperature of this loop is higher than 30C,under this temperature, you know, the risk of bio-fouling is high, however we don't want to install another exchanger to cooling the water temp. down, that would be a large expending. We think a cooling coil twisting around pipes maybe available.
Who could suppy me this or give any useful information.
Thanks®ards

RE: Cooling purity water without a exchanger.
Personally, I am sceptical about wraping a cooling jacket around a pipe.
Cooky.
RE: Cooling purity water without a exchanger.
You can go in for a pipe in pipe heat exchanger.The inner pipe will be your existing pipe.You need to do an outer pipe to circulate the cooling medium
RE: Cooling purity water without a exchanger.
Yes you're right, I prefer to install a wrapping cooling jacket around the pipe to cool down the water temp.
The diameter is DN40, and the peak temperature in summer is 35C.
I have contacted some suppliers but they cannot provide us with this unit you mentioned, could you introduce some vendors for us?
Thanks

RE: Cooling purity water without a exchanger.
but I couldn't open the link you gave. and you mentioned that double pipe exchanger, we also call it concentric tube exchanger, I think that would be a good solution to our problem.
Dear greg87,
Our existing distribution system pump purity water via a VDF pump, the setting point must keep the flow rate in loop at lease 6m3/hour above, therefore we ciouldn't avoid the pump from heating the purity water.
