Water Chiller for Hydroponics, 1/3 HP, 800W, Up to 79 Gal, Titanium Coil

Keep your roots cool, oxygenated and rot-free, all summer long.

Warm nutrient solution holds less dissolved oxygen and invites root rot. The Artisun 1/3 HP Water Chiller holds your reservoir at the temperature you set, so RDWC, DWC and Dutch bucket systems stay in the 65–68°F zone where roots thrive, even when the grow room runs hot under the lights.

Why growers choose it

• Up to 800W (≈2,730 BTU/hr) of cooling from 1/3 HP compressor, sized for reservoirs and RDWC systems up to 79 gal (300 L).
• Pure titanium heat-exchange coil won't corrode or leach metals into your nutrient solution. Safe for fresh water, nutrient mixes and salt water.
• Digital set-and-forget controller. Dial in your target temperature and the chiller cycles itself on and off to hold it.
• R290 natural refrigerant. High efficiency with near-zero global warming potential, so you get more cooling per watt than older R134a and R410a chillers.
• Runs on a standard outlet. 110V / 60 Hz and only 3.2 A, so it shares a 15 A grow-room circuit with your lights and pumps.
• Ready to plumb, two ways. Connect directly to Artisun's 8-gallon 2-site and 4-site RDWC Systems using the included 12 ft of 3/4" reinforced tubing, PVC fittings, couplings, hose clamps and PTFE thread-seal tape. For aquariums, standalone reservoirs and other applications, use the included submersible pump, 1/2" tubing and connectors. Inlet and outlet are 25 mm male threaded.
• Compact footprint. 11.5 × 11.5 × 13 in, small enough to sit beside your tent.
• Backed by Artisun. U.S.-based support from the team that designs our RDWC and DWC systems
