Need help for Titanium tube

yes, copper has a much better thermal conductivity than titanium. In fact titanium is not a good thermal conductor. It is used in marine because it has better corrode resistance property than the rest of the metal. Copper, ppl fear corrode and will create Cu oxide will leak into main tank and corals cannot withstand high copper.

Alternative is to use aluminum, thermal conductivity is in between the 2 and so far I do not see any articles saying aluminum may affect corals....

Just to share what I know.... correct me if wrong. :)

Copper works fine. I'm using copper coil. The copper is not exposed to the water, it is coated.

Always something more important than fish.

Hi, Bro Fuel...

Is it DIY or commercial Chiller?

Probably shows how the DIY coated copper coil cooling setup for your tank? Any idea what kind of coating?... copper not exposed to water? means protected by coating or off water? I trust your setup... I learn lots from your thread :) Pls advice ya... Thanks..

But personally I dun suggested uses them as we know their weakness...

Pls find some info I searh from web

Some chiller used Teflon-coated copper.. which suggested routine Visual Inspection required:

In the better models of chillers, the heat exchanger and compressor are held rigidly together, NOT with a flexible connection. The two metals most commonly used in the heat exchanger are titanium, and Teflon-coated copper. Titanium is expensive and is not a good conductor of heat, however, it is impervious to the saltwater that can corrode many other types of metal. When using coated copper, routinely perform a visual inspection of the unit. Any crack in the coating can expose the copper to the saltwater and result in increased copper levels in the water, with possible toxicity and death of the inhabitants.

One of the statement

The chiller, which is used for commercial purpose should not be used as it may contain copper and, kill all your fish anytime.

Some reefer suggested:

If it is marine, then you will not be able to use copper or aluminium in direct contact with the aquarium water, as it dissolves into the water and will kill the fish. I would be equally careful with freshwater as well.

Cheers and Happy Reefing...

It's the commercial dip-in coil chiller. I'm not really sure what the coating is but it feels like some kind of polymer of sorts. The coating seems quite durable and should not come off, unless the coil is being dragged about on rough surfaces (unlikely to happen in the sump anyway).
