Equipped with premium international burners and smart PLC automation, the WNS series delivers smooth load adaptability and ultra-low NOx emissions. It is the ultimate low-maintenance, fuel-saving thermal solution for pharmaceuticals, food processing, textiles, and packaging industries worldwide.
Note: Customized energy-saving economizers and condensers can be integrated to boost thermal efficiency to over 98%.
1. Burner – Italy Baltur or other brands as specified.
2. Control Cabinet – Full automatic PLC system with English display.
3. Water Pump – Brand optional; variable frequency supply for energy savings.
4. Economizer – Optional to improve thermal efficiency.
5. Water Treatment – Options based on water quality, such as softening or reverse osmosis.
Standard configuration shown above; other accessories like condensate recovery, deaerator, and pressure tank are also available. For details, please send an inquiry.
1. Maximum Thermal Efficiency (≥98%): Integrated energy-saving economizers and condensers reuse waste heat from flue gas, boosting total efficiency while reducing fuel costs.
2. Wet-Back Design & Compact Layout: The wet-back reversal chamber is fully immersed in water, avoiding rear tube plate damage from high-temperature smoke. The skid-mounted or quick-assembly designs ensure a compact footprint.
3. Corrugated Furnace & Safe Operation: Features a corrugated furnace and threaded fire tubes to flexibly handle thermal expansion and prevent fatigue cracks. Equipped with smart PLC automation for automatic ignition, water level adjustment, and remote monitoring (Internet of Things).
4. Clean and Environmentally Friendly: Features an advanced low-NOx burner to meet strict environmental regulations (NOx emission ≤30mg/Nm³).
5. Quick and Effortless Installation: The optional skid-mounted base allows users to start the boiler immediately after simply connecting water, electricity, and fuel on-site.
6. Expert Burner & Water Treatment: Standard components include world-class burners (Italy Baltur or specified brands), full automatic PLC control cabinets, high-quality water pumps, optional economizers, and water treatment systems (softening or reverse osmosis).
