500L Integrated Thermal Tank
Large-capacity water tank with efficient heat pump system ensures fast heating/cooling and stable performance.
Reliable Dual Water Pump System
Euipped with two separate water pumps : One pump delivers water from the main unit into the float tank and circulates water through the tank, filter, heater, chiller, and UV for efficient heating/cooling. The other returns water from the float tank back to the main unit. Independent systems ensure stable performance and efficient operation.
Dual-Mode Energy Efficiency
Pure heat pump mode cuts energy use by around 80%, while hybrid mode maintains around 35% savings with instant heating.
HEALTH BENEFITS OF FLOAT SPA
● Zero-Gravity Floating
*The floating experience removes pressure from the body, offering relief for the back, neck, and joints.
*Ideal for people with desk fatigue, poor posture, or physical stress.
● Accelerated Muscle Recovery
Cold therapy (down to 0°C) reduces muscle soreness, inflammation, and swelling after intense workouts or physical strain.
● Deep Mental Relaxation
The quiet, enclosed float environment mimics sensory deprivation, helping to reduce anxiety, lower cortisol levels, and improve emotional balance.
● Better Sleep Quality
Floating sessions calm the nervous system and promote melatonin production, leading to deeper, more restorative sleep.
● Improved Blood Circulation
Alternating cold and warm water therapy stimulates vascular function, enhances blood flow, and supports cardiovascular health.
● Enhanced Detoxification
Warm floating at 38–40°C opens pores, promotes sweating, and supports the body's natural detox process.
● Increased Focus & Clarity
Post-float mental clarity and focus are commonly reported — great for stress relief, creativity, and cognitive reset.
● Balancing Body & Mind
Regular float sessions support holistic wellness, aligning the physical body with emotional and mental well-being.

ADVANCED TECHNOLOGY FOR THE FUTURE OF WELLNESS

Safe & Hygienic Design
Automatic UV sterilization, ozone sterilization and filtration ensure each session is clean, safe, and low-maintenance.
Dual-Mode Thermal Control
Heat pump enables both deep chilling and efficient heating, combining cold therapy, hot therapy and float therapy in one capsule.
Hybrid Heating System for Rapid Performance
Combining high energy-efficiency heat pump with auxiliary electric heater, the float system can rapidly reach target temperatures, with lower energy cost and precise thermal control.
Cold Floatation at 0°C
Experience the ultimate relaxation and recovery through the integration of cold therapy and floatation, enabled by advanced heat pump technology.
Our specially formulated magnesium salt solution has a freezing point below 0°C, allowing the heat pump to safely and reliably deliver water at 0°C or even below 0°C without the risk of freezing or damaging the heat exchanger.
The directional back-focused cold immersion design aligns with traditional Chinese medicine principles, effectively avoiding direct abdominal exposure to cold water — a key consideration for users with digestive sensitivities.
