Aquarium Chiller Introduction
Fish, corals, and other creatures are considered cold-blooded. Meaning to say they live with no independent body control – it is the environment that controls their internal body temperature. Aquariums need not be hotter than 83 degrees Fahrenheit no matter what the situation is.
When exceeds, the water oxygen level begins to minimize, which eventually causes a competitive- disagreeable condition for the inhabitants to acquire oxygen. That’s where aquarium chillers come very beneficial.
What is Aquarium Chiller?
As the name suggests, aquarium chiller is a piece of equipment used for cooling the water in a tank by controlling the temperature fluctuations due to heating, climate, and by devices related to aquariums (e.g., light) as well as keeping the tank at a nice cool working temperature. This is especially ideal if the tank has a partial or direct sunlight contact or you operate a hot workspace or home.
How Does it Work?
An aquarium cooler is generally composed of various components: condenser, expansion valve, compressor, and heat exchange coil.
It works by simply getting rid of heat from the water and then moving it to another place (called heat exchange). While there’s a “cool” term, it doesn’t necessarily mean that the tank’s water would become cold. It doesn’t work that way.
It all starts with a good heat exchanger. Here, the refrigerant absorbs the heat from the water being circulated in your unit. The compressor will now pump the refrigerant vapor to reach the condenser once it’s cooled. It will then sent back to the heat exchanger for another process of removing heat from the tank water.
Factors to Consider When Choosing the Best Small Aquarium Water Chiller
We aim to ease down your search, so here are some crucial factors for you to ponder on when selecting the right device.
Type of Chiller Aquarium
In-line and drop-in are the two types of aquarium cooler. The former is best for vast tanks and saltwater reefs, while the latter is mostly available with saltwater reef setups. Also, would you rather opt for a fan or a water chiller?
For example, you’ll want to invest in a corrosion-resistant material. This is good both for saltwater and freshwater. Units that are made from superior plastic materials are preferable as well.
Make sure to read the information before laying out money thoroughly. It must fit well to the size of your aquarium.
Go for one that’s not too fast or too slow when using. The right flow rate guarantees a stable water temperature throughout.
You surely have enough expenses. Seeing a spike on your electricity bill is the last thing you want to happen. Hence, it makes sense to opt for a chiller that only consumes less energy as possible.
Some models produce a lot of noise, so be mindful of those. Check out what customers are saying about the operation noise to give you an idea.
Various models now incorporate technology to make the chiller environmentally-friendly – called refrigerant liquid. It emits a cooling effect without harming the environment. HFC-134a and EcoFluor R410 are some of the most popularly used refrigerants.
Is keeping a unit not really your forte? We suggest you obtain models that only require less care, like iPettie Chiller.
