Giesemann Polaris chillers have good looks, chilling price

The Giesemann Polaris chillers are small, compact refrigeration units that can be placed outside your aquarium. Giesemann’s line of Polaris aquarium chillers are made in Germany with a external aluminum case that is power coated in black metallic. The outside display uses a blue LCD screen which allows you to see the current temperature and other necessary notifications. In the back, you’ll find an air filter that will alert you when the filter has become obstructed, something that we haven’t seen aquarium chillers include in their models.  Giesemann states that the Polaris refrigeration units feature a 30% increase in efficiency versus previous models by using a Titanium heat exchanger. The best feature in our humble opinion is the silent feature, which like all aquarium chillers is a popular item with your significant other keeping the noise down from the Polaris while still giving your tank a nice cool water stream. There are three models in the Polaris chiller range (500, 1000, 2000) with the Polaris 2000 model being able to pull down 800 liters to a very cool 12°c (53.6°F). These high-end chillers aren’t cheap, but most chillers aren’t. Pricing starts at €600 and tops out at €900 for the largest Polaris series.
