• Triple coil structure is adopted by the boiler with three-pass flue gas,compact design and space-saving. Heating efficiency of the air pre-heaterenhance up to 92% or more.
• Multiple running with safety protection make boiler's operation more safetyand simply. High temperature control precision (± l'C) and good combustioneffect.
• Automatic control functions, to extend the service life of equipment whilesaving human resources.
