Water circulator with temperature control

I built a water circulator that can supply heated or chilled water to various other shop projects. 

Eurotherm 2132 with platinum RTD (eBay)
CPC quick-disconnect hose fittings (eg McMaster 5012K79)


  1. You mentioned that it was able to heat water as well.
    Is this setup able to keep a water bath at constant temperatures in the range of 40-90C ?
    It might be able to power an awesome supersized Sous-vide bath :D

  2. The hoses and pump are not really rated for 90*C, but I'm sure it could do 40*C. I figured there might be a task in which I might need heated water, and the heater was already built into the system that I salvaged.
