If you're raising coldwater species of fish, you'll need water chiller equipment to help maintain the temperature of your water. We carry both large and small water chillers, including drop-in tank chiller devices, in-line chillers, and saltwater-friendly marine chillers. In addition, we have a range of chiller barrel packages, cooling fans, heat exchangers, and heat pumps. You'll find all of the water chiller equipment you need at Pentair AES.

In-line chillers are available both as air cooled and water cooled, depending on how the unit disperses heat. Which type is better for your tank will vary based on factors such as space, location, and ambient air temperature. No plumbing is needed with coil tank chillers, which simply drop a cooling coil into the water to chill it, but water circulation is required. Chiller barrels use refrigerant to cool water, and do need an external condensing unit. If you have a smaller bait or research tank, an ice probe may be your best option. These small, low-power water chillers can chill 10 gallons of water to 20°F below the surrounding temperature.

  1. Coolworks Ice Probe®

    Coolworks Ice Probe®


    • Efficient—directly converts electricity into cooling.
    • Reliable—fan is only moving part.
    • Easy to install—one hole, one nut.
    • Safe—low voltage operation.
    • Environmentally friendly—no chemicals or gases.

    The Coolworks Ice Probe® uses advanced thermoelectric technology to directly convert electricity into cooling power. Its unique and patented design is based upon Peltier's principle, making the Ice Probe® a highly efficient miniature heat pump! The durable aluminum probe is coated with an FDA-approved finish, making these units ideal small coolers for miniature aquariums, bait tanks, bioassay research, hydroponics and even potable water systems.

    The units are capable of cooling 10 gallons of water 20ºF below ambient temperature in an insulated tank (just a few degrees in a non-insulated tank with heavy lighting). Probes can be mounted through the side of a tank, using the molded bulkhead kit included (1 1/4" hole required) or can be immersed (probe end only).

    Temperature controller is not included; we recommend TC11.

    Weighing only 2 lbs, each Ice Probe® includes a separate 12VDC power supply and draws only 50 watts. Ship weight 5 lbs. One-year warranty.
