The perfect air-to-gas ratio allows the system to achieve optimum combustion conditions for maximum thermal efficiency and optimum environmental emissions. The output range of the full premixed variable frequency condensing boiler is from 20% to 100%, which makes the heat output more precise. It adopts the world's advanced structural design, and the assembly method of the piece and the piece is more convenient for disassembly and maintenance. It is a house, a villa, a school, a kindergarten, Ideal for high-end venues such as swimming pools, hot springs, hotels, hotels, shopping malls, and office buildings.
Ouke full premixed condensing boiler performance characteristics:
Energy saving
1. Based on the function of condensing and full premixed metal fiber burners, the thermal efficiency is up to 109.1%, the exhaust gas temperature is close to the return water temperature, and the PVC chimney is used, which can save up to 40% compared with conventional boilers.
2, silicon aluminum alloy has high thermal conductivity, acid resistance and oxygen corrosion, coupled with mature technology and durable design, can bring you excellent thermal conductivity and service life, has been used in Europe for 35 years history.
3, Ouke full premixed frequency conversion condensing boiler can realize idle speed -100% frequency conversion adjustment according to the heat demand, accurately perform adaptive frequency conversion output heat, saving you more gas.
4. According to the length of use in one year, the fuel cost saved in 1-3 years is equivalent to the price of our equipment.
Environmental protection
1. The precise gas-air mixing ratio of the fully premixed frequency conversion condensing boiler, fully and evenly burning, the nitrogen oxide emission can be as low as 30 mg/m3 (200-300 for ordinary boilers), leading the world, without fear of the strictest environmental protection. Provisions.
2. The stainless steel burner wound with metal fiber burns evenly without thermal shock, and the noise caused by the roaring flame and the carbon generated by the flame impacting the furnace body are eliminated, and the operating noise of the boiler is less than 45 decibels.
3. The exhaust temperature of the full premixed variable frequency condensing boiler is close to the return water temperature, and the lowest can reach 30 °C (the common boiler exhaust gas temperature is generally 160-280 °C), and the local heat island effect is not generated.
intelligent
1. Each boiler is equipped with an American imported controller that has undergone domestic adaptation, which is more suitable for the domestic operating environment, ensuring the stability of operation and achieving unattended operation.
2. The controller has a communication interface of 232 upper computer for remote control. The heating and water supply mode switch gives you more options.
3. Increase the emergency stop switch. In order to prevent the sensor failure on the furnace body, the furnace body is damaged due to lack of water in the furnace. A number of protections ensure the safety and stability of the boiler.
4, outdoor climate compensation control and time-sharing partition temperature control technology, according to the outdoor temperature changes to adjust the heating water supply temperature, to avoid excessive room temperature, resulting in waste.
5, boiler modularization and group control technology can achieve energy savings of 20~25%, can control up to 6 boilers
6, Ouke high efficiency boiler can be matched with the building automation system, can control the temperature of each area, domestic hot water temperature, swimming pool heating and solar energy.
Safety
Overpressure protection system: After 6 water pressure test, when the water pressure exceeds 6bar, the boiler will automatically stop running;
Imported exhaust valve: Exhaust the air generated by the water circulation in the boiler to ensure the normal operation of the system and prevent corrosion;
Fully automatic combustion safety control: whether the real-time burner burns, if there is no flame, the air inlet is automatically closed to ensure the safety of the system;
Low water pressure protection: always check the boiler water pressure. If the pressure is lower than 0.8 kg, the boiler will automatically shut down;
High temperature safety protection: If the furnace water exceeds 95 °C, it will automatically stop the furnace;
Over-limit overheat protection: boiler water temperature exceeds 105 °C, automatic shutdown;
Flue gas temperature safety protection: The flue gas sensor detects the flue gas temperature. If the flue gas temperature exceeds the limit, the system stops running;
Frost protection: When the boiler water temperature is as low as 4 °C, the boiler will automatically heat up to 15 °C to avoid frosting (boiler power must be turned on)
Pump anti-rust card protection: If the boiler is not used for a long time, the pump will automatically run regularly and regularly;
Legionella bactericidal protection: the water temperature in the domestic hot water storage tank is lower than 60 °C for a long time, it will produce Legionella, and the boiler will automatically run at regular intervals to achieve a water temperature of 65 °C to avoid the formation of Legionella;
High and low voltage protection: the boiler will not be damaged due to voltage changes;
High specification control scheme: The controller has 232 interface for remote signal control and diagnosis;
Easy to install and maintain: The boiler is compact, small and lightweight for easy installation and maintenance.
