GEX COOLWAY BK-C220 Cooling System

This is the GEX aquarium cooler COOLWAY BK-C220.
I purchased it new at a store, used it for about 1.5 years, and then stored it for about 6 months.
It has been cleaned by circulating fresh water internally.
Cooling function has been confirmed.

It automatically cools when the temperature deviates from the set temperature detected by the sensor. If you connect a heater separately, you can also adjust the temperature to your desired setting during winter using the sensor.

It was very convenient for temperature control.
It will be sent in its original box, wrapped in bubble wrap.
