## Overview

The Hydro Innovations 904490 Ice Box is a cutting-edge water-cooling solution designed to optimize your grow room's environment. Featuring a high-quality heat exchanger, it effectively retains CO2, enhancing plant growth while reducing the load on your air conditioning unit.

## Description

Finally, a safe, very efficient way to water-cool your entire grow room! It consists of a high-quality heat-exchanger with molded plastic housing that is designed to install over a 6" or 8" air-cooled reflector duct flange. Air from your indoor garden is either pushed or pulled through the reflectors with an inline fan and then passed over the Ice Box heat exchanger. Cold water is circulated through the heat exchanger, cooling the air before it exits right back into the indoor garden area. The longer the tubing the higher the pump. But don't use too high of a pump, due to the fact that it may not allow adequate time for the water to chill. If humidity is an issue in your room, you may want to put the reservoir outside the room. 1/4 HP minimum chiller size is recommended per 1000 watts. 600-900 gph pump needed depending on the length and size of the tubing. Approximately 250 cfm of airflow is needed to properly cool the fixture. Several units can be daisy chained together using one fan, only 250 cfm is needed though all fixtures. For maximum efficiency we recommend one Ice Box per reflector. Allows you to keep a sealed room and helps keep pest and pathogens out of the room. The CO2 stays in the room instead of exhausting out. By running the water approximately 20 degrees colder than your environment it can reduce the cooling load or replace your a/c unit.

    How to use an Ice Box effectively.
  

*by D***S on Reviewed in the United States on April 18, 2014*

Hydro Innovation's 6" Ice Box heat exchanger is very effective at removing heat from a sealed room.However, to remove the heat produced by a single 600W - 1000W bulb, you will need to either daisy-chain 2 of them together or purchase an 8" Ice Box instead.  Also, keep your reservoir below 50F.  (The colder the better.)Once you've configured your system properly, connect the blower and the circulation pump to a thermostat.  (It will blow too cold to leave on continuously.)To avoid freezing your reservoir into a solid block of ice, add propylene glycol (available on Amazon).  DO NOT us car antifreeze.  Ethylene glycol will DESTROY your pumps!Another problem you will encounter is surface condensation. The cold, moist air produced by the Ice Box will deposit copious amount of water on any surface which is colder than the air with which it comes into contact.  Unless you enjoy mopping up standing water, insulate ALL exposed surfaces.Finally, you'll need to address the condensate produced by the heat exchanger's fins.  Basically, the Ice Box spits water.  One solution is to periodically stop and start your system (i.e. cycling) long enough to allow the condensate to drain into in a drip pan for removal or reuse.  (It's clean water.  Why not reuse it?)  Alternatively, you could configure your ducting to remove the condensate without cycling your system.Have fun!

    Great when coupled with the right equipment!
  

*by B***Y on Reviewed in the United States on December 31, 2014*

I doubt the individuals giving poor performance reviews are using this to its full potential. To get the absolute best performance out of this, you Must have a water chiller (I'm using a 1/4HP aquarium chiller) And reservoir to store the thermally depleted liquid (i.e., cold water. I suggest a 150-160 qt marine cooler. Bigger is better!) with at MINIMUM of 600 gpm pump circulating. The thermal transfer rate on this is better for gardening purposes and for low volume air turnover, compared to any automotive heater cores, IMO. Automotive cores are designed for large volume air transfer and should be diffused throughout the area, to not create cold spots and plant damage (i.e. think of one foot really hot in a car and the other ice cold when the heaters is on). Let me just say, it will work but I'd rather save the hour or two of fabrication time for other purposes. I also suggest air diffusion for more extreme cold temps (50 deg F water temp and below, my res sits at 60F). I use this as an air chiller for my recirculation system and it's amazing dropped my temps to 72-74/66 with an ambient temp 74-75. I run a 250w in a 2x2x5. I could imagine under full load, this would be able to nullify a 1000w but the water chiller would cycle MUCH more frequently.

    A decent way to control heat
  

*by R***S on Reviewed in the United States on May 6, 2020*

So right off the bat you going to need to understand that the water source you circulate water from is going to have to be large I used about a 3-gallon container of water and custom made a mini fridge mounting the radiator on top of it with lines going into the water that's refrigerated and even with that after hours of use the ability to cool off the air decreases warming the water source I have considered buying a 55 gallon drum and filling it with water with the thought process that the water could not be heated enough to decrease the temperature more than a few degrees. I feel like this way of cooling would only be plausible in Spring and fall
