Hey sccob, why wouldnt a 2hp chillking do thw job? My room will require 20,000btus of cooling( (4) 1000 watt, dehumidifier. the chillking provides around 28,000btu. Its the industry's best chiller.
how are you running the chiller? with an air handler or using heat exchangers? you just said you are going bare bulb (no glass) in your hoods. does that mean you are using air cooled hoods but taking the glass out? bad idea if so. a lot will depend on how exactly you are removing the heat from the room and your equipment.
you don't have to sell me on chillking chillers bro. i've owned 3 of them in the last few years. right now i have 2 of their units and i did have their 2hp "window" unit for a long time. i've been doing water cooled grow rooms for almost 5 years now. including water cooled reservoir coils, co2 generators, ballasts compartments, air handlers, and even water cooled dehumidifiers. the unit may be rated for 28,000btu from the factory but that will drop slowly over time. either way, just from experience i can tell you that the only way the 2hp chiller will work is if you are only using it with a 2hp air handler and have no other equipment hooked up to it; or you arejust using it with heat exchangers on every hood. even then you might still need a small ac.
also, don't get the 50 gallon reservoir. the smaller your reservoir the better. if you look at their self contained units you'll see that they all have small reservoirs. my 3hp unit has a 20 gallon reservoir and my 12hp unit has dual reservoirs. one is 30 gallons and the other is 20 gallons. you need dual reservoirs when you are running water cooled air handlers and other water cooled equipment that's on the manifold line.
