What kind of equipment is the quote for? Controllers can vary, valves are relatively standard, piping can vary (especially from PVC to Coolfit to Copper). I set up our pilot location for somewhere in the neighborhood of $1-$1.5k (I'd have to double check) for 2X7 BBLs using PVC, building a BCS-462 based controller and Red Hats from Grainger. Depending upon the run from the chiller to the FVs and the process piping, it could get pricey (i.e. if they're quoting copper).
And before the "don't use PVC" comments come flying in, the pilot location is only expected to be in place for 18 - 24 months tops with PILOT usage. After that, we're installing Coolfit.
