CWDR series fully automatic electric heating boilers are boilers that use secondary energy - electricity as an energy source, which can replace coal, oil, gas and other boilers that use biochemical fuels as fuel. They can be used to supply heating and domestic hot water, and can also produce steam. For industrial and daily use. It has the advantages of good environmental protection effect (it is a real environmental protection product), high degree of automation, thermal efficiency as high as 98%, safe and reliable , small footprint, low investment, convenient installation and operation, etc. It is suitable for use in large cities, scenic spots, hotels, scientific research institutions, hospitals, schools, institutions, etc. with high requirements for environmental protection conditions and crowded ground, as well as for small and medium-sized towns, power supply stations, substations, etc., which are rich in hydropower and thermal power resources. Anxin series electric heating boilers are mechatronics equipment, using imported PLC programmable controllers, and the automatic operation of the system is realized through programming.
