Mini Chiller 200 – a cooler with a capacity of up to 225 litres

The Resun Mini Chiller 200 is a compact unit for aquarists who need to keep water temperature under control, especially in summer. It handles tanks up to 225 L, with 160 L recommended as the comfortable working range, and it fits in a standard cabinet without a sump.

Why it matters

• Cooling and heating: the unit can lower water temperature and also raise it, so one device covers both seasonal extremes.
• Compact footprint: dimensions of 200 x 280 x 330 mm and a weight of 8 kg make it practical for small or tight spaces.
• Titanium components: the construction is based on titanium parts used for the cooling process.
• Quiet electronic control: operation is described as silent, and temperature is set through electronic programming.

What it works with

The chiller is intended for freshwater and marine aquariums up to 225 L, with 160 L and smaller tanks recommended. The manufacturer's test example used a 100 L tank starting at 32 °C with flow set to 600 l/h, where the temperature dropped by 7 °C after 5 hours and by 11 °C after 14 hours. Lower flow is stated to improve cooling efficiency.
