I get a laugh out of guys who come on this site with a bag of crap and when they are told it's a bag of crap they get all offended and start blaming the regular participants (and calling them names) for pointing out it's a bag of crap.
In this particular case, the OP said this"Give me your thoughts, options or recommendations on the most cost effective time efficient method to ease this guys troubles." I don't believe anyone on this site is an "elitist faggot". I think what everyone tried to point out is that changing compressors, TXVs and adding water cooled condensers wasn't going to be cost effective solution to the OP customer's problem. The FACT that the owner of the brewery has tripled the size of the brewery, wouldn't it stand to reason the size of the chiller will have to be tripled as well? The OP says the original chiller was sized for a 400 gallon system. I want to know what kind of magic anyone in this world could perform on a 2.5 T machine and turn it into a 7.5 ton machine. Compressors, TXVs and water cooled condensers won't do it...the OP never mentioned anything about the evaporator. How in the hell can one get anymore capacity out of a system without including the evporator in the equation?
Seriously, Pr0dukt, some basic thermodynamics would have given you your answer. You didn't need to come on here and insult the many people who have WAAAAAY more experience than you. And if your customer has more than doubled his production that means he has to be selling more product so his pleas of poverty aren't striking a chord with me. The craft brewery business is a serious money maker.
Perhaps moving on to another forum would be the best course of action for you. There's nobody on this forum that knows anything.
