The Ice Box is a water-cooled heat exchanger that can be used to cool the hot air generated by your lights. With this system, you can do away with your in & out ducting and keep everything but the water chiller inside the garden!
There are several great advantages to sealing your room including superior CO2 efficiency (by keeping your CO2 in), reduced opportunities for pests or disease to reach your plants and easier odor control.

Is water-cooling actually more effective and efficient than air-cooling?
Yes, and here is the science to prove it: Water has a thermal conductivity of 0.6 W/ (m*K) which is much higher than the thermal conductivity of air which is only 0.03 W/(m*K). Water also has a much higher specific heat capacity than air. What that means is water can absorb and remove from your garden 4 times the heat nearly 20 times faster than air! Air is only cooled with electricity whereas water can be cooled in dozens of ways with little or no energy. Furthermore, only 30% of the energy used in air conditioning is converted into usable cooling power, the rest is wasted. In addition to cooling the heat from lights, if the water running through the Ice Box is cold enough, it can actually add supplemental air conditioning to your room, making them great for every operation from hut to warehouse.
How does the Ice Box work?
The Ice Box is a safe and effective way to cool the air leaving your reflectors, without adding AC or more fans. Essentially, cold water is passed through the Ice Box, a fan blows the hot air from your high intensity bulbs through the Ice Box's chilled coils, with the resulting exiting air coming out cold.
Do I have to use RO water with Ice Boxes?
RO water is not necessary to use with the Ice Boxes.
Do you have to use a manifold for small Ice Box systems?
In very small and simple setups, you can daisy chain 2 units together because the water temperature will only have a small rise after the first Ice Box. For larger systems, it is recommended to use manifolds for water delivery to multiple Ice Boxes.
Do Ice Boxes add humidity to the room?
No, the Ice Box does not add humidity to the room because it is a sealed water system.
How do I mount the Ice Box to my reflector?
Use the self tapping screws with the Ice Box to firmly attach it to the reflector. (Do not depend on tape to hold it in place.)
Should I use 6" or 8" Ice Boxes? Which is better?
The 6" model has 36 square inches of surface area (6"x6") while the 8" has 64 square inches (8"x8"). The 8" Ice Box has almost double the cooling power due to higher heat exchange area than the 6".
