Kangdan Sen fully premixed high-efficiency condensing boiler
 

1、Features of KangdanSen Full Premixed High-Efficiency Condensing Boiler
●Silicon-aluminum alloy heat exchanger, with stronger corrosion resistance
●Stainless steel burner wrapped with metal fibers for more even heat distribution
●High-efficiency premixing technology for optimal gas-air mixture and complete combustion
●Condensing environmental protection technology: KangdanSen's nitrogen oxide emission evaluation grade is far superior to the EU's 5-star environmental protection standard
●15-100% infinitely variable frequency adjustment
●The temperature difference between flue gas and boiler return water is 3-5°C for high efficiency and energy saving
●High efficiency even under high power conditions, with thermal efficiency of up to 108.9% at 50/30°C and 97% at 80/60°C
●KangdanSen boilers can be matched with building automation systems, and can simultaneously control the temperature of various zones, domestic hot water temperature, swimming pool temperature, solar energy systems, etc.
●KangdanSen furnace can control up to 16 boilers (1 main boiler and 15 subsidiary boilers)
●Compact design: small size and footprint (1 ton boiler occupies only 1.6 square meters)
 

2、Outstanding safety system
 

●Overpressure protection system: When the water pressure exceeds 6 kg, the boiler automatically stops running.
●Automatic exhaust valve: Exhaust the air produced by water circulation in the boiler to ensure normal operation of the system and prevent corrosion.
●Ion probe: Check whether the burner is burning. If there is no flame, the air intake is automatically closed to ensure system safety.
●Low water pressure safety protection: Constantly check the boiler water pressure. If the pressure is lower than 0.8 kg, the boiler will automatically shut down.
●Temperature safety protection: If the boiler water temperature exceeds 95℃, it will automatically shut down.
●Secondary overheating protection: If the boiler water temperature exceeds 105℃, it will automatically shut down.
●Flue gas temperature safety protection: The flue gas sensor detects the flue gas temperature. If the temperature exceeds the limit, the system will stop running.
●Antifreeze protection: When the boiler water temperature is low to 4℃, the boiler will automatically heat up to 15℃ to avoid frostbite. (The boiler power must be on)
●Water pump protection: If the boiler is not used for a long time, the water pump will operate regularly and periodically.
●Legionella protection: If the water in the domestic hot water storage tank is not used for a long time and is below 60℃, Legionella will be generated. The boiler will run automatically at regular intervals to raise the water temperature to 65℃ to avoid the growth of Legionella bacteria.
●High and low voltage protection: The boiler will not be damaged due to voltage fluctuations.
●Domestic hot water antifreeze protection: Choose O-mode, the boiler water temperature will be fixed at 10℃ to avoid frostbite (power must be on).
