It is energy-saving and high-efficiency, with a maximum thermal efficiency of up to 106%. It operates efficiently, stably and safely. Adopting an integrated overall design, the boiler features an attractive appearance, supports free modular combination, and comes with simple installation and convenient transportation. It is widely applied to venues with heating and domestic hot water demands, including schools, hospitals, hotels, catering establishments, commercial residences and government institutions. It is also suitable for all places requiring industrial water heating.
1. Full Condensing Technology
Innovative structural design with advanced dual-stage (air preheating + flue gas condensation) condensation heat exchange technology. While maximizing heat output, it fully absorbs the waste heat from flue gas. The exhaust temperature can be as low as 1-10°C above the return water temperature, achieving superior heat transfer efficiency with thermal efficiency reaching up to 106%.
2. Ultra-Low Nitrogen Emissions
Integrated water-cooled surface combustion with precise air-fuel ratio control maintains the optimal mixing ratio at all times. Low-temperature blue flame combustion ensures more complete combustion and ultra-low emissions of harmful substances, with nitrogen oxide emissions far below 30mg/Nm³.
3. Fully Intelligent Control
Full inteligent one-click operation, real-time dynamic interface,automatic recording of operational data, user-triendly operation, comprehensive security protection, efficient, stable, and secure operation, and easy loT integration.
4. Advanced Insulation Technology
The boiler employs "air insulation layer" technology, with aluminum silicate and mirror aluminum foil applied to the furnace surface, significantly reducing heat loss.
5. Stainless Steel Heat Exchanger
Made of SUS304 stainless steel with multi-pass straight-tube arrangement for high heat exchange efficiency. Can be used in single, parallel, or series connection to meet different heating requirements for temperature and pressure.
6. Selected International Top Components
Cooperation with top global boiler component suppliers provides high-quality, reliable components, ensuring long-term stable operation of the equipment.
7. Extended Service Life
The boile operates in a vacum environment, preventing scaling and corrosion.With thermal medium water and system water isolated, t ensures anexceptionally long service life.
Widely used in schools, hospitals, hotels and restaurants, commercial residences, government units, and other places with heating and domestic hot water needs, as well as any industrial water heating facilities.
