The SF-LN05C is engineered with a proprietary dual-mode system that spans a massive thermal range from a near-freezing 1℃ up to a spa-like 40℃. Because it utilizes high-end Sanhua 4-way reversing valves and an inverter compressor, facility owners can offer both frigid cold plunges and heated muscle recovery in the exact same footprint without needing two separate machines.

Yes. Due to the massive 16.3 kW cooling output and 5HP compressor size, the system requires a stable 380V~415V / 50Hz / 3N power supply. This industrial electrical framework ensures the machine runs smoothly at maximum load, prevents voltage drops, and extends the lifespan of the internal electronics, which is crucial for high-traffic wellness centers.

The Coaxial Titanium heat exchanger is fundamentally impervious to the corrosive effects of chlorine, bromine, Epsom salts, and body oils. Unlike traditional stainless steel plate heat exchangers—which can suffer from pitting and corrosion over time—our titanium core guarantees zero rust, zero chemical degradation, and prevents dangerous internal blockages.

Absolutely. The SF-LN05C is rated for ambient operational temperatures ranging from -10℃ up to 45℃. It incorporates smart defrosting algorithms and robust hardware designed specifically to withstand harsh seasonal changes, guaranteeing your spa operations can run continuously regardless of the weather outside.

The integrated sanitation system is highly automated. The Ozone (O3) generator operates seamlessly without needing refills, effectively oxidizing bacteria on the fly. The primary maintenance involves routinely checking and washing or replacing the 20-micron filter cartridge, depending on user volume. Because the filter traps oils and debris before they enter the machine, it dramatically reduces deep-cleaning labor.
