Featuring a high-quality heat-exchanger, it retains CO2 for improved 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. ## Features - Efficient way to water-cool your entire grow room - Consists of a high-quality heat-exchanger - CO2 stays in the room instead of exhausting out - Reduces load on A/C unit ## Images ![904493 Ice Box, 8-Inch - Image 1](https://m.media-amazon.com/images/I/41F8Srd+32L.jpg) ![904493 Ice Box, 8-Inch - Image 2](https://m.media-amazon.com/images/I/41F8Srd+32L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ It's built for desert growers *by M***G on May 20, 2021* Better than ac!! I grow in my garage and I live in the middle of the desert so it gets really hot in my garage. I bought an ac unit to cool my garage off but it acts like a dehumidifier and sucks all that humidity I've been trying to pump into the air right out. I bought this with a chiller and hooked them straight into the tent with an 8" fan blowing it in to the tent and it dropped the 120 temp to 65 without cooling the air before. If your growing in the desert in your garage it is a must buy!! ### ⭐⭐⭐⭐⭐ Cool... product *by D***M on May 10, 2021* Working great with my diy chiller. Takes a huge load off my ac in my upstairs apartment I have it connected to a 8 inch ac infinity fan blowing towards my couch and it feels great it’s pricey but performs well ### ⭐⭐⭐⭐ Nice addition to cool environment *by G***S on November 2, 2019* Very good device but it sweats in hot and humid environments, two rubber plugs at the bottom let out the water. Keep in mind when using in your environment as it will need to be bled periodically. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.nz/products/5329246-904493-ice-box-8-inch](https://www.desertcart.nz/products/5329246-904493-ice-box-8-inch) --- *Product available on Desertcart New Zealand* *Store origin: NZ* *Last updated: 2026-05-16*
