Customer of ours orered a 11kw chiller from us to cool their new plasic sheet maker.
The spec was done by themselves and we just delivered it etc. Commissioned on Monday all good to go. Got a call on wednesday "Chiller isn't working water temp now at 54 deg's c"
Went to site on Friday and chiller was working but with a return temp at 45 and rising! A bit under sized..poor little chiller .
They plumbed through the 3x 300mm dia rollers in series with 15mm id areoquip type hoses by Pirtek to which we said they would have to go as they are too small. (500 quid down the drain)
We will re-pipe with larger 25mm id but in parallel which we feel would lower the return temperature in any case.
So a 11kw is too small but how would we go about sizing it as we were thinking of a 26 or 37kw in a that's gotta be enough type scientific way
