Flow-through boiler Super Equos EQi-2000/2500 NM/LM

Flow-through boiler Super Equos EQi-2000/2500 NM/LM

This is the birth of an environmentally friendly boiler that pursues the value of the boiler itself and has the industry's best environmental performance and energy-saving capabilities.

In recent years, as there has been a strong demand for equipment with excellent environmental and energy-saving properties, we have achieved ultra-low emission combustion with NOx=25ppm using a low air ratio with restricted combustion air, making us the first in the industry to do so.
