The Best Aquarium Chillers in 2022

Perfect for use with an aquarium, this quarter HP chiller will maintain just the right temperature for your fish to thrive. It is capable of maintaining a consistently cool temperature. It uses R410a refrigerant liquid and is therefore completely freon free. There is no annoying loud noise and it has an easy to understand LCD display to control its microcomputer operation.

There is a sizable refrigeration capacity of between 26 and 80 gallons and it can chill 80 gallons of water by 15 degrees F. If your aquarium holds only 26 gallons, it will chill it by 30 degrees F over 20 hours as it has a high flow rate of between 264 and 660 gallons per hour. Because the evaporator is made from pure titanium, it does not corrode and can therefore be used with both fresh and saltwater.

Zoo Med’s aquarium cooler is the ideal water cooler for smaller tanks – around 5-10 gallons.

These happy customers have been generally thrilled with the result and said that it has proven a worthwhile purchase for aquarium owners on a budget. It is quiet, low voltage, easy to attach, and simple to use.

An effective solution for temperature regulation issues within your aquarium. This fish tank chiller will work well in smaller aquariums. It has a quiet operation and is both reliable and efficient thanks to the advanced thermoelectric technology. It runs on electric power which is converted to cooling power to reduce the temperature of the water. You can bulkhead it through a one and a quarter inch gap in a siphon overflow or it can easily be fitted to prefilters and sumps. You can fit it directly into plastic aquariums.

The chilling action is continuous so there is no on/off switch to worry about however, you will need to use a separate temperature controller to control when the chiller is turned on and off to maintain your required temperatures. The device is capable of chilling 10 gallons of water by around six or eight degrees F. In larger aquariums, it can chill 20 gallons of water by three or four degrees F or 40 gallons of water by just one or two degrees F. Therefore, you may need to use multiple units if you have a large aquarium.

This 1/15^th HP aquarium chiller has a clear digital LED temperature display that gives the temperature in degrees F and can be read easily in the day or at night. It can be used to effectively chill up to 40 gallons of water.

Not only that, but the fan itself does not consume much power, saving you money on your electric bill. The fans of this cooler have been specially designed to minimize water disturbance, whilst maximizing airflow.

Though this fan can be extremely effective in maintaining the temperature of a smaller tank, should you choose to attach it to a larger tank you may want to think about using it alongside another, more heavy-duty water cooling device. Larger tanks benefit from more penetrative cooling methods, and whilst this fan is great for maintaining the surface temperature of the water in a large tank, it may not be able to permeate deep enough to cool the entire thing.

This is a cost-effective solution to aquarium cooling. It is a set of two compact fans that have a two-speed control. They are capable of reducing the water temperature by around two or three degrees C.  They fit onto the aquarium using adjustable jaw clamps and will suit any aquarium with walls up to 1.2cm thick.

The BAOSHISHAN aquarium chiller is an ingenious design that keeps your aquarium cool with minimal disturbance inside the water. It is capable of easily cooling an 80-liter tank (so long as it doesn’t have high-powered lights or pumps) from 82F to 77F. This not simply a cooling fan, but a refrigerated cooling pump. By this, we mean that it works alongside your tank with a pipe submerged deep within the water, a secondary pipe hovering above the water, and a temperature probe. It will then measure the ambient temperature of the tank, and begin to steadily pump water through the titanium coil cooling system. Once the water is cooled it will be redistributed slowly back into the tank via the pipe overhead.

This cooling system is suitable for both freshwater and seawater tanks. Though there are a couple of things you should consider before purchasing one. If you have particularly small fish, be wary of the possibility of them getting pumped into the cooling system; whilst it is not a powerful pump, it can still be a risk to tiny fish. Additionally, this unit does need to operate alongside your tank, so be sure that you have plenty of space in the display area before setting it up. All in all, not only is this a highly effective piece of aquarium equipment, but the customers have also remarked on the professionalism and sincerity of their customer service.

This is unique to the other aquarium chillers on our list due to a single, extremely helpful feature; the Inkbird ITC-208S is not only a chilling system but a heating one as well. Specifically, it is a temperature control system, which makes it especially useful for tropical fish owners, where temperature control is extremely important. Often tropical temperatures in an aquarium cannot be reached or maintained without the use of an aquarium heated – that is where the Inkbird comes in. It is capable of monitoring the temperature of your tank constantly, adjusting between heating and cooling modes to keep it at the optimum temperature.

It is perfectly suited for both freshwater and saltwater tanks. Additionally, an extremely helpful feature well worth knowing is that this device also has high and low-temperature alarms as well as sensor-failure alarms. This means that if the tank starts to get too warm or drop too cool, you can come to manually adjust that temperature and ensure your fish stay comfortable. It is a piece of equipment well worth having, especially considering the company has an automatic one-year warranty on this product, to give you peace of mind whilst trying a new piece of unfamiliar equipment.
