High efficiency once-through boiler

High efficiency once-through boiler SEN-CS Series SEN-300CS/400CS/500CS/600CS/800CS/1000CS/1500CS/2000CS/2500CS/3000CS

This is a high-quality, high-efficiency boiler manufactured with optimal design and strict quality control.
Product Features
  • High efficiency is achieved by installing a specially processed, pressurized, high-performance water preheater in the main body, which is designed with an efficient two-row water pipe arrangement of a unique structure.
  • This is a high-efficiency boiler that reduces heat loss by absorbing as much of the high-temperature exhaust gas heat generated after combustion as possible in a high-performance feedwater preheater, resulting in significant savings in fuel costs.
  • By adopting a fully automated method, water supply, operation, and burner combustion devices are automatically controlled with a single switch, and various safety devices are attached so anyone can use it with confidence.
  • When equipped with the artificial intelligence control device SE-Ai system, operation and maintenance become easier. (Optional)
