Need chiller advice for concrete wet room

[lbartz]

I've seen this sort of thread before and I'm sorry to post again, but we are trying to find an appropriate chiller to cool down our moist room. I just received a quote for a $4,000 model but I don't know enough about chillers to know if they're pulling our leg. Can anyone here tell me what chiller you have and the approximate size of your moist room? Some days our water is coming in at 86F and that's keeping our room at 79 or 80F but we need it to be 77F and below. Any help would be greatly appreciated!
