The Yukon System

Experience the perfect synergy of durability and technology. We have paired the reinforced YUKON Gen 3 tub with our high-performance Smart Chiller to create a fully automated recovery station that maintains your exact temperature — clean, cold, and ready when you are.

Key System Benefits:

Precise Dual-Action Climate (3°C – 42°C): Don't just plunge — control. Our powerful compressor (0.8HP–2.0HP) delivers rapid cooling for ice baths or soothing heat for muscle relaxation. With WiFi connectivity, you can schedule your session and monitor temperatures directly from the Smart Life App.

"Smarter Flow" Sanitation Cycle: We re-engineered the YUKON’s water inlet to perfectly match the chiller’s circulation speed. This optimized flow works in tandem with the chiller’s Ozone sterilization and 20-micron filtration, ensuring your water is turned over faster, cooled more efficiently, and stays crystal clear.

Reinforced & Weather-Ready: Built for the outdoors. The YUKON Gen 3 features a heavy-duty reinforced structure that stays rigid, paired with upgraded all-weather security straps to keep your cover locked down in harsh conditions.

Plug-and-Play Setup: No tools, no plumbing. The system connects in seconds using industrial quick-connect hoses. Whether you choose the Gen 5 Pro or Elite engine, the system is designed for instant setup in gyms, patios, or home studios.

Key Benefits

Heating & Cooling

Delivers precise cooling down to 3°C and heating up to 42°C with the integrated Borealis™ system.
