Product Introduction
CYH series premixed low-nitrogen condensing gas boiler adopts advanced full-premixed combustion and condensing heat recovery technology. It is fueled by natural gas or LPG. The metal fiber burner realizes uniform surface combustion, effectively reducing NOx emission. The high-efficiency condensing heat exchanger recovers latent heat from flue gas vapor, achieving ultra-high thermal efficiency. Equipped with frequency-variable fan, proportional gas valve and PLC intelligent control system, it supports stepless load adjustment, low-noise stable running and multiple safety interlock protections. Widely used for central heating and hot-water supply in hotels, schools, hospitals, commercial buildings and industrial plants.
