Product description
This listing is for one 1/3 horsepower aquarium chiller rated to manage water volumes up to roughly 79 gallons (300 liters). The unit uses a compressor-based refrigeration system to lower and hold aquarium temperatures when integrated into a compatible circulation loop. What’s included is a single chiller unit; verify the packaging and the manual to confirm any additional connectors or mounting parts required for your setup.
The internal heat-exchange element is titanium, which provides corrosion resistance and makes the chiller suitable for both freshwater and saltwater applications. That material choice also supports use with reef aquaria, axolotl enclosures and compatible hydroponic reservoirs where biocompatibility and durability are important. The unit’s external fittings are metal and designed to accept standard aquarium tubing; check the manual for exact hose sizes and adapter needs.
Power is supplied in a configuration intended for use with standard US electrical systems; always confirm the electrical rating printed on the unit and read the installation instructions before powering on. Performance will vary with ambient room temperature, total water volume, the heat load from lighting or equipment, the flow rate through the chiller and how well the unit is ventilated. Allow adequate clearance for air flow and avoid enclosed spaces that trap heat.
Install the chiller into your system after you have established reliable water circulation: connect a compatible pump and tubing and confirm steady flow before switching the chiller on. Position the unit on a stable, level surface and keep ventilation openings clear so heat can dissipate. For complete setup details, accessory compatibility and safety guidance, consult the supplied manual and any labels on the packaging.

Became Noisy
After a few uses it developed a loud rattle. Sounds like something may be loose; it's distracting and hard to live with.

Great for Sensitive Systems
Excellent for reef and axolotl setups — brings temps down reliably and keeps them stable. Setup was intuitive, build feels solid, and it cycles reasonably though it produces some heat and compressor noise.

Solid and Reliable
Dropped temperatures quickly after installation. Sturdy casing and fittings, quiet in normal operation, and the clear front display is handy.
