Keeping the RED cool.

[Tonaci Tran]

I read about the Soderbergh films using gel packs and cooling barneys to keep the camera cool. Anyone have any recommendations the best brands to buy or best place to get them?

Thanks! =)

You can get dry-ice at most grocery stores. Dry-ice is pretty cheap and it would be much longer lasting than standard freezer packs. Otherwise, go to any drug store and get some gel packs.

Watch out for condensation...

Water ice is cheaper, easier to handle, more available, and I believe more effective in this particular case. Specifically, water ice will absorb more energy before melting than dry ice will before sublimating. After that point, with water you've still got the cold water (which may be still useful for cooling, or messy, depending on if your container is waterproof) but dry ice goes to CO2 gas which is neat & tidy, but provides no further cooling.

Dry ice: 199 kJ/kg (enthalpy of sublimation)
Water ice: 333 kJ/kg (heat of fusion AKA specific heat of melting)

Yeah.. definitely. Especially in humid regions..

A lot of people are interested in a barney, both for cooling and noise blimping:

And somebody mentioned a cooling barney already here:

But has anybody actually made one yet?

Sure!:wink: In audio terms I am creating a feedback loop, hoping that it creates some attention to this important issue.

a ColPack (cold therapy- medical use -for elbows, knees etc) works ok - put in freezer - it remains flexable so you can wrap it around the shape of the camera ..
doesn't last as long as blue ice ...

We're still working with developing out the prototypes... material changes.
