This raises, at least for me, some interesting questions. I don't get the modern obsession with modelling. When I was growing up, models were somethin...
@jamespa - I agree about the need for stats on real world numbers on system failures caused by freezing, but I am not sure they exist, meaning we have...
@jamespa - I am still stuck in an uncertainty loop about the effects of glycol on system performance. Starting at the beginning, why add glycol in the...

@amanda1 - I regularly bang on about compressorgate, not whether it will happen, but when it will happen. All big manufacturing industries are on the ...
