Hi Melinda,
Check out air condensers like these.

I would definitely make sure you evaluate these for your particular process before letting them go overnight though.
As you say, recirculators are a great option as well.
All the best,
Kristi

Subject: [DCHAS-L] flood prevention question
Hi, all,
We recently had a flood due to an insecurely attached hose on a water-cooled condenser set up overnight.
So I am on the hunt for ways to reduce this risk, besides attaching the hose more securely. I know there are recirculating system options, but I don't know what's suitable for overnight cooling.
All input welcome,
Thanks,
Melinda Box, M. Ed.
