Cooling Diesel on Gen Sets
Cooling Diesel on Gen Sets
(OP)
We have some diesel units installed indoors within a building, this facility is located in areas with design day + 122F. So we would like to cool the fuel on the return path as to improve a bit our performance. Our project owner has asked us if the only way to cool the fuel is with a plate type heat excnager, for example is their a water type heat exchnager to take advantage of our cooling plant.
Any ideas or products out there

Main concern is to get with your engine's manufacturer and get his spec for fuel return maximum restriction.
Hope that helps,

Depends on how cool you want it? You could also use a refrigeration unit to cool the incoming fuel.

If you are using Ultra Low Sulphur fuel, then fuel lubricity can be a problem at fuel temperatures above 100 degrees F. There are a lot of varibles, and depending on your fuel system design this coould a minor issue or a big problem.
We install shipboard systems using shell and tube HE's, if you have a chilled water supply, use an appropriately sized heat exchanger with seals suitable for fuel, such as Viton. You will need to get with your engine manufacturer and get the typical heat rejection to the fuel, and the maximum allowable return line restriction to size the HE correctly. We use Sendure heat exchangers for this in the marine market.

Otherwise as mentioned by others any water to oil heat exchanger with seals to suit your fuel. The fuel won't know if the heat exchanger is a marine engine oil cooler or a hydraulically operated machine oil cooler, so long as the size is adequate and the seals resist your fuel.
