Built to a standard, not a price.

Every component was chosen for reliability and efficiency - here's where it shows.

Up to14°Fof cooling per hour
Up to20°Fof heating per hour
High-Power Cooling

Built for serious cooling power

Double-loop condenser coils push extra cold for hot garages and peak summer.

Won't corrode, won't clog

Double-walled titanium heat exchanger resists corrosion and keeps water flowing unrestricted with optimal heat transfer.

Optimized cold in any climate

Smart sensors adjust cooling for hot or cold weather, with dry-run and freeze protection.

Heating mode comes standard

Heating and cooling come standard on all our chillers for your choice of contrast therapy.

ENGINEERED, NOT ASSEMBLED

A look inside

No hidden corners cut. Every component is here because it makes the chiller more reliable, efficient, and powerful.

Built to Last

Protected where water sits

Stainless steel base and hardware guard the spots most susceptible to rust.

Electronics that don't cook out

The capacitor sits in the cooling airflow, so it runs cool and lasts.

Quiet, efficient, self-protecting

A LEFOO brushless water pump runs quiet and strong with safeguards for long-term reliability.

Never come home to green water

Auto-resetting GFCI restarts after a power outage; most brands stay off until you notice.

Double-wall titanium heat exchanger
INSIDE THE TITANIUM CORE

Double-wall titanium heat exchanger

Heat transfers between your water and the refrigerant along the entire ribbed path - more surface area for faster, more efficient cooling. And because your water flows through one large titanium pipe, not the narrow channels of a plate exchanger, it can't corrode, clog, or scale up over time.

Smart & Connected

Full control through PrimalOS

Adjust settings and schedule filtration and cooling from anywhere.

Advanced on-screen diagnostics

Maintenance reminders to your phone

A heads-up before anything needs attention, sent straight to you.

One clean, connected system

A single cable powers the tub and PrimalOS touchscreen, all on one GFCI.

Easy Maintenance & Premium Details

30-second, no-mess filter changes

Top-mount filter housing - swap filters in seconds, no draining or tools.

No drips, no heat gain

Insulated hoses with threaded ends stop condensation and keep water cold.

Premium valves included
