Hailea HC Water Chiller — Titanium Heat Exchanger

Hailea HC Water Chiller — Titanium Heat Exchanger

For hydroponic growers who've lost a crop to pythium, the Hailea HC Water Chiller is the single most important piece of kit you're missing. It keeps your reservoir nutrient solution in the 18-20°C sweet spot year-round, dramatically boosting dissolved oxygen and shutting down the warm-water pathogens that destroy root systems.

Why growers choose the Hailea HC Chiller:

• Pure titanium heat exchanger — won't corrode in salt-laden nutrient solution like copper or steel would
• Works in freshwater and saltwater — suitable for hydroponic reservoirs, aquaponics, and marine applications alike
• Protects against root rot — pythium thrives above 22°C and shuts down below 20°C; the chiller maintains that boundary
• Boosts dissolved oxygen — cooler water holds more O₂, directly improving root health and nutrient uptake
• Plug-and-play setup — works like a mini-refrigerator for your reservoir, minimal plumbing required
• Multiple models available — sized for reservoirs from 100L up to commercial volumes

Who it's not for:

If you're growing in soil or coco with hand-watering, a chiller isn't useful — this is for recirculating hydroponic systems (DWC, NFT, RDWC, flood & drain). Check your reservoir size matches the chiller model; undersized units will run constantly and burn out early. You'll also need a pump to circulate water through the chiller.
