About This Product

Product overview
■Zero CO2 emissionsAchieved both low NOx and energy savings, which have been long-standing issues with hydrogen combustion. Hydrogen has the characteristic of increasing the generation of nitrogen oxides (thermal NOx) when it is combusted, and until now this has been dealt with by lowering efficiency compared to boilers that use natural gas as fuel. This small hydrogen-fired once-through boiler has achieved both low NOx and high efficiency (rated boiler efficiency 98%), which had been a challenge for many years.

■Dry type low NOx burnerWhat made this possible is the newly developed "dry low NOx burner." This overcomes the previous weakness of reduced fuel efficiency and suppresses the generation of nitrogen oxides (thermal NOx) while maintaining high efficiency.

■Features・Eco-friendly low NOx (certified by Tokyo): 50ppm (O2=0% conversion)
・Safety design: Nitrogen purge function
・Easy to handle: No boiler engineer license required
・High durability due to high quality steam・Energy saving・Stable steam supply: Steam pressure fluctuation ±0.005MPa
