Best Res material

[lonepig]

I'm building a waterchiller but am having no luck finding a of the counter res for my evap coil. As its a old freezer unit the coil is 48cm*48cm so I need a large res. Also its made of steel so I can't find a pipe bender that will do the business.

As a result I'm gona make a res for it out of some sort of plastic, I was just wondering what sort people would advise due to the sub-zero conditions it will live in.

Just go to home depot and try and find a cooler that will fit it, its way easier than making your own that will withstand those temperatures.

Unfortunately i've been to all the stores near me and the only thing big enough was a water tank. And that was way to big.

Ebay would have coolers too if your willing to go there.
