CoolWorks Chiller
How Does The IceProbe Small Aquarium Chiller Work?
By using our IceProbe solid state thermoelectric cooling system, the Aquarium Chiller directly converts electricity into cooling power utilizing the Peltier effect. The chiller’s probe cools the water by removing heat and radiating it into the atmosphere through fins with the help of a quiet, low-speed fan.
Since no compressor is needed for thermoelectric cooling, the Nova Tec Small Aquarium Chiller is extremely reliable and requires no refrigerants, so it’s environmentally friendly.
Cooling Performance
A single IPAC-50W chiller can cool 10 gallons of water 6ºF to 8ºF below ambient air temperature in a standard aquarium. Multiple Aquarium Chillers can be used to achieve higher temperature differentials.

Greater temperature differentials can be achieved by insulating the exterior surfaces of the aquarium. For example, a single Aquarium Chiller can maintain a temperature differential of over 20ºF in a fully insulated 10 gallon aquarium.
About Thermoelectric Technology
In 1834, French physicist Jean Peltier discovered that when electrical current is sent through a circuit made of dissimilar conducting materials that heat is absorbed at one junction and given up at the other. This phenomenon is known as the "Peltier Effect."
Evolving from Peltier's original discovery, today's thermoelectric modules (TEMs) are highly efficient heat pumps, directly converting electricity into cooling power.
Most thermoelectric modules utilize bismuth telluride, doped to obtain p (positive) and n (negative) semi-conducting properties, to achieve optimum heat pumping performance. Sandwiched between the ceramic exterior of a TEM are many small pieces of n + p doped bismuth telluride coupled together and connected electrically in series. When connected to a DC power supply, current causes one side of the TEM to absorb heat (the cool side) while the other side gives up heat (the hot side). If the current is reversed, the heat is moved the opposite direction reversing the hot side and the cold side.
With their small size, efficiency, reliability, and environmental friendliness, TEMs are becoming widely accepted as the most effective cooling source for many applications.
