IceProbe Aquarium/Water Chiller Information

How Does the IceProbe Small Aquarium Chiller Work?

By using 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 CoolWorks 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.

Typical Temperature Pulldown (°F)
# of Chillers 10gal 20gal 40gal
1 6-8ºF 3-4ºF 1-2ºF
2 10-12ºF 6-8ºF 3-4ºF


Easy Bulkhead Installation

IceProbe Chiller Setup

With its threaded probe, nylon nut, and silicon washer, the IceProbe can be readily installed through a 1.25 inch hole into siphon overflows, prefilters, sumps, aquariums, or virtually any type of water reservoir.

Provided that the probe is fully submerged in water and air can freely circulate around the IceProbe’s fins and fan, it can be installed through a top, side, or bottom wall.

IceProbe Chiller Hole Drill

The hole can be easily drilled through a plastic or acrylic wall using a standard hole saw available at most hardware stores. An experienced glass cutter should be consulted for bulkhead installations in glass aquariums. Alternatively, a simple bracket or lid can be used to suspend the Aquarium Chiller for top mounting in glass aquariums.

Before installing the Aquarium Chiller, it is important to ensure that there is adequate clearance for the probe and ample space for air circulation around the fins and fan.

IceProbe Chiller Bulkhead InstallationTo achieve the best possible watertight seal, the silicon washer should be installed on the dry side of the wall as shown in the diagram to the right.

In larger aquariums (20 to 55 gallons), two or more Aquarium Chillers may be needed to achieve the desired temperature differential. If possible, install your first IceProbe so that additional units can be added if more cooling is required.
