Summer holidays started some days ago and, as promised, a University professor provided me with a old immersion circulator. He confirmed this thermal circulator has not been used with dangerous chemical or bio stuff.
Nevertheless the appliance was looking dirty with a sort of sediment all over the immersed parts. I took time to clean it gently. Here are the pics of my new toy!
So far I only checked if the Julabo was working well and plugged it to my water bath and set the temperature at 58°C.
The water pump is noisy and very powerful. I think it could cause a problem if using a small pan instead of my high water capacity water bath. The Julabo EC heated my 20 litres water bath in some minutes (the manual indicates 2,000 watts) which is noticeable compared to the 20 minutes waiting time for the gas stove, halogen stove and water bath former ous vide cooking experiments.
The only drawback of Julabo EC immersion circulator is the way to set temperature. You have to turn a wheel to set the temperature but their is a gap between the actual temperature indicated on the screen and the one set on the wheel. Therefore you need to adjust manually the weel to fix the target temperature appearing on the screen. It seems this problem doesn’t exist anymore with Julabo’s last EC version.
This version of the Julabo doesn’t benefit from a float switch which is a security problem if you want to cook for long time periods.
