@leadsled is correct, Quest FTW.
Same Manufacturer behind all of them but Quest was made for Hydroponic Indoor use and that makes the unit much easier to warranty.
My company recently put together a chart depicting which size unit would handle how many light fixtures...
At 7,000 watts the Quest 155 is your best option, 205 would be great but overkill IMO. The 155 pulls roughly 6 Pints/ Kilowatt, weighs 140lbs and is roughly 2'x2'x3'
@Coir that 105 pulls 8.8 pints per kilowatt, I highly doubt there is another unit, especially a portable, that is more energy efficient. Take into account when your unit is not operating in recommended temps (80F/60RH) it bogs the unit down and becomes much more of a hog to run. This is the reason portable units, or any other unit that draws down low is extremely inefficient.
Remember this too, dry air attracts moist air, meaning dehueys do not need to be evenly distributed. The room will even itself out.
The last option from Surna should actually read 405 pints/day...
