Ice Boxes are water-cooled heat exchangers that can be used to cool the
hot air generated by HID lighting systems in sealed hydroponic setups.
With these systems, gardeners can do away with “in and out" ducting and
keep everything but the water chiller inside the garden. Whether they’re
used for controlling the heat from lights or for replacing an air
conditioner altogether, gardeners should see a significant drop in their
cooling energy requirements. Because water can absorb heat 20 times
faster than air, an Ice Box is typically twice as efficient as air
conditioners. Efficient use of an Ice Box heat exchanger requires an
appropriate high-quality chiller, a 30-50 gallon reservoir, a
properly-sized pump, Ice Boxes for each of your reflectors, quality
tubing and miscellaneous plumbing parts. Wall Mount also available.
