Why the EcoPlus 1/4 HP Chiller Is the Size Most Rooms Land On
Two and a half times the tank capacity of the smallest unit, for a fraction more power draw. It covers reservoirs up to about 80 gallons while pulling 360 W at 3 A. The step up to 3/4 in fittings matters more than the numbers suggest. A bigger circulation pump can move water through the exchanger without choking the loop. That pump wants to land between 264 and 660 GPH. The cabinet is 17.13 x 11.61 x 18.5 in at 42.5 lbs, still a one-person lift. Titanium inside, LCD on the front. It is a floor unit rather than a bench unit, and it needs real clearance for the exhaust.
Matching an 80 Gallon Water Chiller to the Tank It Serves
An 80 gallon water chiller covers most of what a single grow room holds. That runs from a large recirculating tank down to a bank of buckets sharing a reservoir. Sizing works on the tank, not the plant count. The honest check is whether the unit pulls the whole volume down overnight rather than just holding it steady. Ambient air temperature changes that answer, since a hot room takes cooling capacity away from the water. Run the circulation pump inside a filter bag and rinse it between crops. Growers usually set the controller a degree or two below target rather than at it. The sensor reads the return line, not the middle of the tank. If your reservoir is closer to a hundred gallons, step up rather than run this one flat out.
Key Features
- Covers about 80 gallons: The practical ceiling for a single room tank or a shared bucket reservoir.
- Three quarter inch fittings: Lets a larger circulation pump move water without restricting the loop.
- 360 W at 3 A: Still a standard 120V load, so it does not need a dedicated circuit.
- 264 to 660 GPH pump window: Published range for the circulation pump, which removes the guesswork.
- Titanium heat exchanger: Handles nutrient solution and salt water without corroding.
- 42.5 lb cabinet: Heavy enough to stay put, light enough for one person to place.
