CL280 Cooler (up to 300 litres)

The Resun CL280 is a chiller for aquarists whose tanks run warm and need to be held at a set temperature. It is rated for systems up to 300 L and can be used in both freshwater and marine setups, so it suits hobbyists who keep one unit in a mixed or changing setup.

Why it matters

• Compact housing (300 x 320 x 350 mm) allows placement close to the aquarium, which is useful where cabinet space is limited.
• The titanium heat exchanger is designed to keep energy consumption low while maintaining maximum cooling efficiency at 280 W.
• The unit is described by the manufacturer as quiet in operation, which matters if it runs in a living room or bedroom.
• An LCD display allows the target temperature to be set precisely, instead of relying on rough adjustment.

What it works with

The CL280 is intended for aquariums up to 300 L in both freshwater and marine categories. Its recommended flow of 300–600 L/h means it should be connected to a circulation loop that delivers water within that range. Confirm that the flow and tank volume match your system before installation.
