1. Cast aluminum heat exchanger has strong corrosion resistance and fast heat exchange speed
2. High efficiency premixed Technology: full premixed combustion technology and pre mixing air and gas according to the best proportion before combustion can ensure full combustion and effectively reduce nitrogen oxide emission. NOx emission is as low as 8mg / m2
3. Condensation environmental protection technology: Aluminum condensation heat exchanger can liquefy the high-temperature flue gas generated by combustion, further use the phase change energy generated by this part of liquefaction, improve the thermal efficiency of boiler and save the gas consumed per unit calorific value. Thermal efficiency up to 107%
4.15-100% stepless frequency conversion adjustment.
5. The temperature difference between flue gas temperature and boiler return water is 3-5 °, which is efficient and energy-saving.
6. It can be matched with building automation system. It can control the temperature of each area, domestic hot water temperature, swimming temperature and solar system at the same time.
7. Compact design: small overall size and small floor area
Manufacturing basis
1. The boiler design and manufacturing quality shall comply with Annex 2 (acceptance conditions for small and atmospheric hot water boilers) of Shanghai quality and technical supervision special (2003) document and small and atmospheric hot water boilers
Relevant provisions of boiler safety supervision regulations.
2. The heating surface materials, welding rods and wires used in the boiler shall have quality certificates.
3. The steel used for boiler shall comply with GB700 and gb8163.
4. Boiler welding must be performed by welders who have passed the training and examination.
5. The boiler shall be equipped with automatic protection device.
6. The water quality of industrial boiler shall comply with gb1576-2001.
