Replace bags of ice with controlled, recirculating water cooling. The Absolute Zero Standard Chiller is a 0.8-horsepower unit designed to connect to a compatible plunge tub, bathtub adapter, stock tank, or DIY cold-immersion system.
Dedicated Cooling for Home Cold-Plunge Systems
The chiller uses a GMCC compressor and lists 2,200 watts of cooling capacity. Absolute Zero states that it can cool water to approximately 37°F and reduce water temperature by roughly four to eight degrees per hour from a 70°F starting point, although actual performance varies with water volume, ambient temperature, insulation, sun exposure, and airflow around the unit.
A 660-gallon-per-hour submersible circulation pump and 3/4-inch camlock connections support a closed-loop setup. The steel-framed unit is rated IPX4 for protection from splashing water but should still be installed with proper ventilation and electrical protection.

Planning Your Setup
Place the chiller on a stable surface with the airflow clearance required by the manufacturer. Use a GFCI-protected outlet, keep electrical connections dry, and do not use extension cords unless the manufacturer expressly permits the exact cord and load. Cooling rate will be slower in direct sun, high ambient heat, poorly insulated tubs, and larger water volumes.
Frequently Asked Questions
Does the chiller heat water?
The Shopify variant is the Standard Chiller, which is positioned primarily as a cooling unit. Absolute Zero also sells a separate Pro model with heating, WiFi, ozone, and filtration features. Verify the selected variant before purchase.
How quickly will it cool my tub?
Absolute Zero states approximately four to eight degrees per hour from 70°F and advertises cooling to 37°F. Results depend heavily on setup and environment.
Does it include filtration or sanitation?
The Standard Chiller specifications do not list integrated ozone or dual filtration. Add the recommended filtration and water-maintenance components for your setup.
Can it stay outdoors?
It has an IPX4 splash rating, not full waterproofing. Follow all weather, clearance, freezing, cover, and storage instructions.
Cold-water immersion can create significant cardiovascular and breathing stress. Never plunge alone, avoid alcohol or impairment, enter gradually, and seek medical guidance when appropriate.
