EcoPlus 1/10 HP Water Chiller | 42 Gallon Titanium Heat Exchanger

What the EcoPlus 1/10 HP Chiller Is Actually Sized For This is the smallest unit in the EcoPlus range and it is honest about that. It handles reservoirs up to roughly 42 gallons, drawing 264 W at 2.2 A on a standard 120V circuit. Plumbing is 1/2 in, and the circulation pump feeding it needs to sit between 66 and 317 GPH. The heat exchanger is titanium, which is why salt water is on the approved list alongside nutrient solution. Physically it is 15.75 x 8.58 x 16.34 in and weighs 28.7 lbs, so it fits under a bench. A micro computer and LCD handle the set point. Push it onto a larger tank and it runs continuously without ever reaching target. Plumbing a Small Reservoir Water Chiller Into an Existing System A small reservoir water chiller works on a loop of its own rather than in line with the feed. A submersible pump sits in the tank, pushes solution through the chiller and returns it to the same tank. Irrigation timing and cooling then stay independent of each other. Run that pump on a filter bag, because fine root debris is what clogs a narrow heat exchanger. Place the unit where the exhaust side has clear air, since it dumps the heat it pulls out of the water into the room. Keep the hose runs short and insulated where you can. Most growers hold a nutrient tank in the mid to high sixties. A unit this size only gets there on a tank it was built for. Key Features Rated to about 42 gallons: Sized for a single tote, a small DWC set or a propagation tank. Titanium heat exchanger: Corrosion resistant, so nutrient solution and salt water are both fine. 264 W at 2.2 A: Light enough on a 120V circuit that it shares a timer strip without tripping anything. 1/2 in fittings: Plumbs with common half inch tubing rather than needing adapters. 66 to 317 GPH pump window: A stated flow range, so pump selection is a spec rather than a guess. Digital LCD control: Micro computer holds a set point instead of cycling on a mechanical stat.
