Description
The CWNS Gas-Fired Atmospheric Pressure Hot Water Boiler is designed for commercial and industrial facilities that require atmospheric pressure hot water supply. Its non-pressurized structure reduces pressure-related operation concerns, making it suitable for hotels, hospitals, swimming pools, spas, and other non-high-pressure hot water applications. The boiler uses a gas-fired combustion system with a corrugated combustion chamber. It is equipped with automatic start/stop control, automatic water filling, water level alarm, and leakage protection for daily hot water supply, cleaning, heating, and facility water-use applications.
