[labnetwork] Favorite recirculating chiller?

[Mohammad Khodadadi]

Hi Kevin,

If you are looking for room temperature cooling, we have *great experience*
replacing our central water cooling system with *Thermoflex 2500* at the
University of Houston Nanofabrication Center <https://uhnf.egr.uh.edu/>.


   1. The *price is reasonable*. ( you can buy a refurbished one for $2500)
   2. They are *robust *and *portable*.
   3. *Maintenance *is *easy*, *fast*, and *affordable*. ( Basically, over
   time we replace the water pump (1 hr ), the coupling (20 min), or the motor
   (1 hr))
   4. We use *distilled water* as a coolant and Watts Flow-Pro FPMB5-978 as
   a water filter.
   5. We have an SSP

   case you need it.
