Resun CW-1000A Aquarium Chiller & Heater

Keep your aquarium at the perfect temperature all year with the Resun CW-1000A, a powerful 1HP chiller that provides both chilling and heating. It's built for aquariums and systems up to 1,500 litres, and its microcomputer control holds your water at a steady temperature with ±0.5°C accuracy.

Temperature stability is essential for fish, corals and invertebrates, especially in marine systems and through hot Australian summers. The CW-1000A keeps your water at a constant temperature automatically, so you don't have to worry about heat spikes or cold snaps. The dual-button control and dual-screen display make it easy to set and monitor your target temperature, and it suits both marine and freshwater setups.

It's powered by an advanced, highly efficient compressor that's energy saving and environmentally friendly, with a 2,700W refrigerating capacity. A 3-minute delay protection feature stops the compressor restarting too quickly, which helps extend the life of the machine.
