JBJ Nano Arctica E-Chiller - 20G

The JBJ Nano Arctica E-Chiller is a compact cooling solution designed for nano aquariums up to 20 gallons. Built with a thermo electric, compressor-free design, it delivers quiet and energy-efficient operation while maintaining stable water temperatures in both freshwater and saltwater systems.

Unlike traditional compressor chillers, this unit uses a high-performance heat sink and fan system to reduce water temperature by approximately 9–11°F, depending on ambient room conditions. Its small footprint makes it ideal for tight spaces without sacrificing performance.

Installation Notes
For best performance, place the chiller at the same level as the aquarium whenever possible. If installed below tank level, a stronger pump may be required to maintain proper flow. Low flow can reduce cooling efficiency or cause freezing within the unit.

Additional tips:
Keep pump at least 1/2" above substrate
Secure outlet pipe using suction cups
Direct return flow away from the pump intake
