Chilled water to the mould and the machine, with every trip annunciated.
The mould has to pull heat out of the bottle fast enough to hold its shape, every cycle, all shift. That is a chilled water problem, and an under-sized chiller shows up as scrap rather than as an alarm. Ours start at 2.5 TR and annunciate compressor, pump, low pressure, phase and flow on the door.
