I totally agree with Mr. common sense right here.Max-Juice,
even a 2 ton just isn't going to come close to cutting it. it looks like you've got the ballasts and the chiller in the same room. you'd better get your plan together quick for what you're going to do when you throw the switch and that room heats up to 120 degrees with that portable going.
do you have power in place? can you move the ballasts out of the room? if you should need 3T of a/c, how would you do it?
