Fully Premixed Condensing Modular Unit

This product features fully aluminum-cast high-efficiency condensing technology, delivering over 35% higher operating efficiency than conventional boilers—ensuring ultra-low energy consumption and highly stable performance. A 700 kW unit occupies only ~2 m² of floor space yet provides heating for over 11,200 m², meeting large-area heating demands while maximizing space efficiency.

Its compact, lightweight design and wheeled base simplify installation, relocation, and post-installation maintenance—effectively reducing both initial installation and ongoing operational costs. During operation, NOx emissions are reduced to <30 mg/m³ and noise remains below 50 dB, delivering both environmental sustainability and quiet comfort. The aluminum-cast heat exchanger features wide water and flue channels, paired with mature high-capacity fan systems and other core components—enabling simple operation and consistently stable, reliable performance. Key components—including the aluminum-cast heat exchanger—are exceptionally durable and aging-resistant, with a designed service life exceeding 35 years, offering users a long-term, high-efficiency, energy-saving heating solution.
