Variable-frequency wall hung gas boiler COMFORT
Heat transfer type: casing / plate exchange
Optional power: 20/24/28 /32/36/40KW
High efficiency and energy saving:
The fin structure of heat exchanger increases the spoiler structure to reduce the blind area of heat transfer, and the thermal efficiency is over 92%.
Safe and reliable:
By using frequency conversion control technology, the fault of wind pressure switch is completely eliminated. 160V~280V wide voltage design and more than 30 protective measures ensure safe operation under the environment conditions of each region.
Low noise design:
Low noise design, frequency conversion casting aluminum fan, intelligent control system, running noise is less than 42 dB.
The original modular design, assembly and disassembly is simple, fault memory function, convenient for the rapid diagnosis of after sales personnel.
A number of invention patents, VVVF control technology and low nitrogen combustion patent technology are applied, and the NOx emission of products reaches five level.
The original heating and bathroom power is automatically regulated within the maximum range of 25%~100%, improving the control accuracy of domestic hot water, and completely eliminating the overheating phenomenon of hot water in summer.
Imported die stretching, LCD screen display, keyboard type operation, advanced atmosphere.
