[Titan151]

I recently picked up a water chiller on the e-bay. I was a little concerened that it might not be able to cool my system. It seems substantial in heat capacity. It's a titan150 thermo electric chiller (no compressor) and can cool 150 watts. The specs state it can drop the temp of 25 gallons of water by 10 degrees F. The reccomended water flow rate is 50-100 gph. I got this knowing I could always sell it back on ebay so I kept it in good condition. So far I haven't had much time to toy with it, but my initial results show it isn't working well with my set up. My question is, my pump is rated at 280 gph. If i shut the pump off the chiller easily drops the water temp down to 6 degrees c. I am wondering if a slower pump would allow more time for the water to chill thus reducing the temp. I have one and am going to try it out tonight. The other option is to use the chiller in some kind of loop with a seperate pump. This could amount to cooling the water in a reservoir or perhaps the radiator in a submerged container. I will have to toy with other options. It may be too early to jump to any conclusions as I have more to try. Anyone have any info on thermo electric chillers with no compressor? ANy help much apreciated.
