Active Aqua Water Chiller 1/4 HP with Power Boost | 3,010 BTU

Where the Active Aqua Chiller 1/4 HP Fits a Single Room

Output is 3,010 BTU per hour against a recommended reservoir of 40 to 92 gal. The loop needs 396 to 925 GPH moving through it, which is why the 400, 550 and 800 GPH pumps are the ones named for it. Pump choice is not optional here, because nothing is built into the cabinet. Power is 460 W at 120 V and 4.7 A. That is still a standard outlet, though it is enough draw to matter on a circuit already carrying a light. The exchanger is pure titanium and the refrigerant is R134a. Adapters for 1/2 in and 3/4 in tubing are included. The body is 18 x 13 x 17 in and 41 lb, so it wants a floor or a stand rather than a shelf. Set point spans 39 to 90 °F with memory through a power interruption. The part number is AACH25HP and the barcode reads 638104022972.

Chiller Sizing Is Arithmetic, Not Guesswork

The working formula is gallons times 8.33 times the temperature drop you need, which gives BTU per hour. Add about a quarter on top for the room's own heat load and for a compressor that will not run flat out forever. A hundred gallons needing a five degree pull is a little over four thousand BTU before that buffer goes on. Run the test during the hottest hour of the day with every light on, not at night when the room is already cool. Deep water culture asks for ten to fifteen percent more than the same volume in a drain-to-waste table. Ambient air matters as much as water volume, since a compressor in a warm room sheds heat slowly and cycles longer. Boost gives two hours of hard running for the initial pull-down, or it can be left on continuously. The trade-off is noise and heat in whatever space the cabinet occupies. It is a refrigerator, and it behaves like one. Plan the plumbing so the barrel can be flushed, because scale on the inside of the exchanger costs capacity quietly.

Key Features

• 3,010 BTU per hour: Holds a single-room recirculating reservoir through a full lights-on stretch.
• 40 to 92 gal window: Matches the tank size most one-room systems actually run.
• 396 to 925 GPH loop: Pairs with the 400, 550 and 800 GPH pumps named for this unit.
• Pure titanium exchanger: Handles nutrient solution and salt water without corroding.
• Digital set point with memory: 39 to 90 °F, and the setting survives a power interruption.
• Boost or continuous running: Two hours of hard pull-down when the tank starts warm.
