NWNS Industrial Steam Boiler
+25℃ 
+300℃
Features
High boiler efficiency:flue tube type large diameter furnace chamber design,equipped with high efficiency energy saver and condenser,the efficiency can reach more than 100%.
Low heat dissipation loss:three-layer boiler shell insulation, inner layer of ceramic fibre,intermediate rock wool boards,outer lightweight cement, to reduce heat dissipation loss and improve the strength of the outer shell.
Superior Durability: Wetback back wall WET-BACK construction with ample heat transfer area for rugged durability.
Short start-up time:from automatic ignition to the generation of steam at a pressure of 8kg/cm² in about 10 minutes.
Complete safety control:the use of highly reliable triple water level and triple pressure safety controls ensures the safe operation of the system.
