Looking for Industrial Oil Cooler

Looking for Industrial Oil Cooler

Looking for Industrial Oil Cooler

(OP)
I am trying to find an oil cooler for a gearbox.  I am looking at 150 degF oil and 95 degF water.  The ambient air of the area for the cooler is 95 degF in summer.  A quick estimate of the cooling capacity is 10hp.

Does anyone know some good vendors who have a cooler for the above conditions?

Tigerdawg,
Try Affiliated Steam Equipment Company - Milwaukee, WI
Ask for Greg Davis (262) 252-9945

Hope this helps

Thanks for the help.  Other issues prevent us from adding the oil cooler.  We will have to add a cooling jacket to the gearbox.

Try Flatplate, if interested. They make good PHE's for this application.

RE: Looking for Industrial Oil Cooler

I'd be interested in hearing if if the cooling jacket works.  Unless the duty is pretty small, you might not get much heat transfer because of the limited area.  10 Hp is a fair bit of raw heat to dissipate.

RE: Looking for Industrial Oil Cooler

First of all why do you wish to cool the gear oil down to 150oF ? Aren't the fins on the box's external surface enough ? What kind of gear oil are you using, is it a mineral oil or a lubricant based on a synthetic PAG ?

Otherwise, I agree with TD2K. A rough estimate shows that with an overall HTC of about 0.2 kW/(m2*K), a cooling capacity of 10 HP=7.36 kW, and a LMTD of, say, 15oC, you'll need an area of about 2.4 m2. Is the box sufficiently large to warrant a heat exchange surface of these dimensions ?

Don't forget that the resistance to heat transfer with water would be on the oil side, thus whatever one does to the water side (besides lowering its temperature by chilling it) wouldn't change much the overall HTC.
