The Best Aquarium Chiller Reviews



Do I Need An Aquarium Chiller?

An aquarium chiller is very important for maintaining the temperature of a fish tank. In most aquariums, the pumps and light can create a large amount of heat to the extent of affecting the water temperature. In warmer climates, environmental conditions around the aquarium can also contribute to a large amount of heat. Besides creating unwarranted stress for aquatic life, the increased temperature can also reduce the ability of water to hold oxygen. Using an aquarium chiller can prevent this from happening.

In order to supply a comfortable environment for your lovely fish, including jellyfish, coral, shrimp, etc., you need an aquarium chiller, which will help you maintain a cool temperature in summer and warmth in winter. An aquarium chiller becomes even more important if you are in a tropical location.



What Is An Aquarium Chiller?

Aquarium chillers are external units installed in aquariums to remove excess heat from your aquarium through absorption or compression. This device creates a comfortable environment in your aquarium, allowing your fish to overcome harsh temperatures.

An aquarium chiller is a very small device that works like a fridge to cool your aquarium. Cooling in summer and warming in winter, the aquarium chiller decreases the temperature of the water on hot days and prevents water from getting too hot. The more equipment you have running in your aquarium, the greater your need for an aquarium chiller would be.

As the chiller itself emits a lot of heat, you need to ensure that careful planning is made during its installation. The aquarium chiller should have plenty of ventilation in order for it to be useful. Mounting it in an area that is not ventilated, such as an aquarium cabinet, is not recommended because this can cause an increase in water temperature.

As most chillers have thermostats, you can set the temperature that you want your aquarium to be cooled to on the chiller, which then chills the water as it passes through its system to the selected temperature and ensures that the water will not get warmer than you have set the thermostat to. A chiller is normally installed to use the compression method of cooling water that is pumped through the chiller into a heat exchanger. where it flows through cool metallic coils with refrigerant inside them. The aquarium water loses its heat when flowing over these coils, which are constantly being cooled to the temperature that you set on the thermostat. Water then flows back into the aquarium cooler again.

For your lovely saltwater aquarium, it needs not only a heater but also a water chiller to balance the water temperature for your aquarium. A comfortable environment for your fish will be provided if an aquarium chiller is installed.

What Is The Function of Aquarium Chillers?

An aquarium chiller’s thermal units are also denoted as BTUs. Therefore, when choosing an aquarium chiller, it is recommended that you buy one with a relatively higher BTU, as they are more efficient at removing excess heat from your pond. The chiller’s gas will collect all the heat in your pond and then deliver the hot gas to the radiator. In turn, the radiator will ensure that the gas pressure is reduced, and the fan will dispel all the heat from the radiator, thus decreasing the water temperature in your aquarium.


How Does an Aquarium Chillers Work?

Chillers work by eliminating heat from the aquarium water and diverting it to another place. The heat exchange process cools the aquarium water by eliminating its heat, which results in a drop in the water temperature.

The operation of an aquarium chiller is based on the scientifically proven fact that heat moves from a warmer point to a colder one. A chiller’s design is very similar to the cooling configurations typically employed in air conditioning systems and refrigerators.

An aquarium chiller has four key components:

– Heat Exchange Coil (evaporator)

– Condenser Coil

– Compressor

– Expansion valve

The cooling cycle starts in the chiller’s heat exchanger. Here, a liquid refrigerant evaporates and absorbs heat as the aquarium water circulates through the heat exchanger, which is often constructed of titanium that enables it to prevent corrosion by saltwater. Consequently, that also ensures the efficient transfer of heat to the coils.

The compressor then draws the refrigerant vapor out of the evaporator and pumps it to the condenser. In turn, that raises the refrigerant’s pressure and temperature. Later, it condenses and releases heat. The heat is efficiently removed as a fan blows air across the condenser coil.

Liquid refrigerant in the condenser is then passed through the expansion valves, thus reducing the temperature and pressure. Before making entry into the chiller’s evaporator, the coolant flows over the coils again to absorb more heat, completing the water chilling cycle.


How to Choose A Right Chiller for Your Aquarium?

Every manufacturer designs their aquarium chiller differently. To select the best aquarium chiller, there are various things you should consider to determine what your aquarium needs. You can then identify a chiller that meets those conditions. The following four things should be considered when choosing the right chiller for your aquarium:

1: Size of Chiller

Ensure you purchase the appropriate chiller size for your aquarium. The right chiller size will depend on your aquarium tank’s size as well as by how many degrees it ought to be cooled down. Tanks that carry heavy loads of heat from ambient air temperatures, lights, or wave machinery will require a more powerful unit than others might.

The chiller size is usually defined in BTUs or horsepower. Flow rates are often described in gallons or liters per minute. This only describes the amount of water the chiller’s pump must be capable of handling. Flow rate doesn’t represent the amount of water that can be cooled by the chiller.

To determine the amount of water the aquarium chiller being bought needs to cool, you will need to calculate the volume of your aquarium tank. The amount of water contained in the sump should be included as part of the capacity to be cooled down, too.

To determine the volume of water that must be cooled down, you can start with all the lights on and have the aquarium running. Give the water several hours to absorb heat. Then check and note the temperature.

Now, take that temperature and subtract the optimal temperature of operation. That gives you the temperature “pull down” that will be required from the aquarium chiller you intend to purchase. Manufactures usually define the volume of water a chiller can cool.

Usually, if your tank holds about 130-150gallons, you want to keep the water temperature from 32-22 Celsius. It is better to use our LD-1HP aquarium chiller.

We recommend purchasing one or two sizes larger than what is needed. Maximizing the chiller size is a great way to maximize your aquarium’s energy efficiency. In the long run, this will prove to be a significant cost saver.

2. Flow Rate

The flow rate is vital, as it determines how well a chiller can maintain the set water temperature. Pick an aquarium chiller that has a suitable flow rate; the flow rate should not be too slow or too fast.

3. Temperature Control

Single-stage chillers are designed only to cool. These are worth considering if you are sure that the ambient temperature will never drop below the aquarium’s optimal operating temperature.

Dual-stage chillers control both heat and cold. In turn, they are able to maximize temperature control and come integrated with a full thermostatic system.

4. Energy Consumption

Your chiller will run on electricity, which is a factor that makes many people shy away from purchasing a chiller.

However, aquarium chillers are usually constructed to consume little energy, and you can purchase a model that consumes even less energy.

5. Material

Do you need a chiller that will last for many years, right? Then ensure the chiller you purchased is constructed with brand new materials.

Lando aquarium chillers use the best materials, including:

1. Brand new compressor

2. 100% copper tube with low vibration and high heat transfer

3. Pure titanium evaporator fit for saltwater and freshwater

4. Digital LCD temperature

5. Purchasing a Lando water chiller ensures you are getting the right value for your money.

6. Operating Noise Levels

You will want to take the chiller’s noise level into consideration, especially if the aquarium is located in an office or residential space. Lando aquarium chillers are quiet and suitable for offices and residential rooms.

What Types of Aquarium Chillers?

When you decide to buy an aquarium chiller, there are many things you will need to keep in mind, including the type of chiller, the tank size, climate conditions, and flow rate of existing equipment. If you live in a warmer area, it is always a good idea to go one size up with the aquarium chiller in order to make up for the warmer temperature that affects the water conditions in your aquarium. You will also need to get the next larger size chiller if you have an aquarium with a canopy because additional heat will be created by the enclosed setup.

The three types of aquarium chillers available on the market include thermo-electric chillers, in-line chillers, and drop-in chillers.

1. Thermo-Electric Chillers

These chillers are ideal for use with smaller saltwater and freshwater aquariums as well as insulated specimen or bait tanks that feature slow water flow. They use the idea that a current will heat up on one side when sent through two different conducting materials, while the other side will reject heat. They feature a hot side that is insulated from the cool side and a cool side that is pointed toward the aquarium and is responsible for cooling the water. You should only use them for aquariums of up to 55 gallons. When used with aquariums that feature a fast water flow, they are not effective, as the fast flow can overwhelm the chiller and render it ineffective. Apart from being effective on aquariums with slow water flow, they also have the advantage of being very quiet.

2. In-Line Chillers

In-line chillers are suitable for use with large systems with in-line filtration. The cool water is already filtered and is normally used with setups that feature saltwater reefs. They require plumbing in order to fit into an in-line filtrations system. The filtered water runs through the chiller’s coils, where water is cooled before being taken back to an area in the sump. From there, the water is taken into the aquarium through the main return pump. In-line chillers come in different sizes.

3.Drop-In Chillers

If you are looking for the simplest chiller to install, this is what you should buy. Drop-in chillers are comprised of a coil that is placed in a dry or wet filter or the sump of the aquarium. The coil is made of titanium metal. It is filled with refrigerant and then tightly sealed to make it waterproof. It is connected to the compressor of the aquarium by a thermostat. On the market, you will find drop-in chillers in different sizes that range from 1/13 HP to 5HP. They are primarily used by aquarists that have saltwater reef aquariums. As no plumbing is required for installation, they work for systems that do not have a lot of extra space for accessories.
