Description
Hold your nutrient reservoir at 18-20C, whatever the room is doing
Hailea HC-A water chillers are refrigerated coolers that hold a hydroponic reservoir at a set temperature in DWC, RDWC, NFT, drip and flood-and-drain systems. Five sizes cover tanks from 100 to 500 litres: the HC-100A, HC-130A, HC-150A, HC-250A and HC-500A. Every model uses R134a refrigerant, a corrosion-proof pure titanium evaporator and a digital microcomputer thermostat that reads to 0.1C and holds any setpoint between 6C and 30C. Warm nutrient carries less dissolved oxygen and invites root disease; a chiller is the fix that works when a LED or HID room heats the tank faster than the air can cool it. A pump and hose are not included - pair the 100A, 130A and 150A with the Hailea HX8810, the 250A with the HX8820 and the 500A with the HX8825, all sold here.
Key Benefits
- Five sizes, one range - 100L, 130L, 150L, 250L and 500L reservoirs, with published working bands wider than the model name (see the specification)
- Pure titanium evaporator - nutrient solution never touches copper; fresh or salt water
- Digital thermostat with memory - set once; it returns to the setpoint after a power cut
- Compressor protection - automatic over-current cut-out stops motor burnout
- Quiet R134a compressor, LED display, 1 year warranty
- Flow set by the pump you fit - the chiller has no pump of its own, so match a pump to the model's circulation band
Warm reservoirs, low dissolved oxygen and sluggish roots
Once nutrient solution climbs past about 22C it holds markedly less dissolved oxygen, roots slow and pythium and root rot get their opening. Air conditioning the room is the expensive route; chilling the tank keeps the root zone in the 18-20C band independent of the air under the lights. Size by reservoir volume and go up a model if you are at the top of a band or the room runs hot.
How to Use
- Stand the chiller on a flat surface with clear air around the vents; it rejects heat into the room and must never be covered or laid on its side.
- Fit a pump and hose matched to the model - HX8810 for the 100A, 130A and 150A; HX8820 for the 250A; HX8825 for the 500A - on the hose size listed below.
- Circulate water through the chiller first, then switch on. Never run it dry.
- Set the target, typically 18-20C for hydroponics.
- Clean the filter and condenser regularly to keep cooling efficient.

Frequently Asked Questions
Which model do I need for my reservoir?
Size by the volume of nutrient solution you need to hold down: the HC-100A to 100 litres up to the HC-500A to 500 litres. Go up a model if your tank sits at the top of a band, the room runs hot or the lights heat the water, because a chiller working flat out all day struggles in summer.
Does the chiller come with a pump?
No. Each model needs a submersible pump and hose: the Hailea HX8810 for the 100A, 130A and 150A, the HX8820 for the 250A and the HX8825 for the 500A. The pump sits in the reservoir, pushes solution through the chiller and the return hose carries it back to the tank.
Where should the chiller go?
Ideally outside the tent or room, because it releases the heat it removes from the water into the air around it, like a fridge. Give the vents clear space, stand it level and never cover it or lay it on its side.
