Safer Water

Protection Without Compromise

Hot water systems often face a dilemma: high temperatures prevent germs but risk scalding, while lower temperatures invite bacteria like Legionella. SAFA solves this with innovative Contra-Protect technology, ensuring scald avoidance and germs elimination for ultimate safety.

Contra-Protect Solution
Our dual-mode disinfection system kills germs non-stop while preventing scalds. Features include planned coordination for seamless implementation, streamlined installation, meticulous testing, and minimal downtime during changeover.

Non-Stop Disinfection
Eliminates bacteria 24/7 without chemical overuse.

Scald Prevention
Intelligent controls maintain safe temperatures at every outlet.

Super-Available Supply
Reliable hot water on demand, even during peak usage.

Simple Integration
Easily retrofits into existing systems for hotels, hospitals, or residential buildings.

Greener Heat

Efficient and Sustainable Heat

SAFA prioritizes environmental responsibility with direct heating and thermal storage options that reduce energy consumption and carbon footprints—perfect for Hong Kong’s green building standards.

Heat Pumps
Heat pumps are at the core of SAFA’s green heating strategy, efficiently transferring heat from the environment (air or water) rather than generating it through combustion or resistive electric heating. This results in up to 70% lower energy use compared to traditional boilers alone, significantly reducing carbon footprints and operational costs while promoting renewable energy integration, ideal for sustainable commercial and residential applications.

Direct Heating
Unlike indirect systems that rely on multiple heat exchangers (which can lead to energy losses through inefficiencies and added complexity), SAFA’s direct heating approach transfers heat straight to the water source. This minimizes energy waste, boosts overall efficiency by up to 30%, and simplifies maintenance, making it a superior choice for high-demand environments like hotels and hospitals.

Thermal Storage
By incorporating hot water tanks and storage heaters, SAFA stores excess heat generated during non-peak hours for use during high-demand periods. This not only saves energy by shifting consumption away from peak tariffs but also enhances system stability, preventing surges and ensuring consistent performance, ultimately extending equipment life and supporting grid-friendly operations.

Air-source heat pumps draw heat from ambient air to provide efficient, low-emission hot water production. They deliver green heat by achieving high coefficients of performance (COP) in mild climates like Hong Kong, reducing reliance on fossil fuels and cutting energy bills.

Water-source heat pumps utilize existing cooling demand (such as chiller return water) as heat source. They provide green heat by recycling thermal energy that would otherwise be wasted, offering even greater sustainability in urban settings and aligning with eco-standards.
