Pumped chiller units are supplied by a small number of lab equipment manufacturers in Europe/USA. An item with a similar specification to this can be purchased for more than _5k and cheap options don't really exist outside the 2nd hand market (well in my student we once put a pipe coil inside an old freezer and pumped water through that, so there were some limited options). To my mind that price is much higher than the components required can justify but there were few other options. However, the arrival of items like this chiller make effective cooling affordable.The chiller came with a euro power lead and a fuse less adapter for a UK socket (I doubt that can legally be used in the UK) but it was easy to find a suitable replacement. It was shipped with some water still in the tank and had leaked a little, so the product was wet within the plastic wrap. After drying it off the product was none the worse for wear and functioned normally. It is simply but well constructed and functions very well, quickly dropping to a 4degreeC setpoint in our first test.You can't disable the pump so when switching on make sure a pipe is linking the input and output or drop the output pipe into the tank filler otherwise you'll have a fountain.It remains to be seen how reliable this chiller is but so far I am very pleased with it.
