Meanwhile, the company has established a comprehensive service system, providing services such as overseas equipment installation and commissioning, operator training, and 24-hour online consultation. Both the whole machine and key components are covered by warranty, with the after-sales team responding within 48 hours. In addition, the company offers product customization and personalized packaging services to fully meet the needs of customers at home and abroad.

The combustion chamber adopts corrugated furnace to increase the heating area, strengthen heat transfer, and has good thermal expansion characteristics.
The boiler tube sheet and smoke pipe adopt argon arc welding full-position automatic welding to ensure welding quality.
The boiler adopts high thermal resistance material and closed metal cover as the insulation layer, and has good thermal insulation performance.
The backfire chamber adopts a wet back structure, and the high-temperature flue gas is surrounded by water space, which eliminates the phenomenon of cracks in the boiler tube sheet due to thermal fatigue.
The combustion chamber adopts a corrugated furnace to increase the heating area, strengthen heat transfer, and has good thermal expansion characteristics.
It has a rich heating area and a large enough water space and steam space to ensure that the thermal efficiency in the non-condensing state is not less than 96% and the thermal efficiency in the condensing state is greater than 99%.
The boiler adopts a number of advanced environmental protection technologies, a standard three-pass flue gas structure, and is equipped with imported burners, with high combustion efficiency and reduced pollutant emissions.
/ Product advantages /
01
All electrical components use internationally renowned brands to ensure product safety and service life.

02
Each group of electric heating elements is connected by a concentrated beam flange and is independently set up. It has the characteristics of simple structure, high mechanical strength, safety and reliability, easy replacement, and long service life.
03
It has a large steam space and good steam quality;
The electromechanical is installed separately, and the electric control components are far away from the heat source, which is conducive to heat dissipation. It can be used in parallel alone or in multiple units.

04
PLC microcomputer programmable control and display screen; The temperature setting is realized through the human-machine interface to automatically control the water outlet temperature. The display screen can display the equipment status operating parameters and fault alarms.
