ADVANTAGES
EFFICIENT AND SUSTAINABLE

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.

Aesthetically pleasing: the front smoke box door is equipped with additional heat insulation panels, which is aesthetically pleasing and at the same time reduces heat loss and provides a favourable operating environment.

High performance combustion system: The advanced combustion system provides a uniform temperature field in the combustion chamber, high combustion efficiency, and easy operation and maintenance.

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 8 kg/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.

Easy Maintenance: Because of the simple and sturdy construction of the body and combustion system, the operator or maintenance personnel can handle the maintenance work.
