There is no need to report for inspection when using vacuum hot water boilers, which can save a lot of time for enterprises and can improve production efficiency after quick commissioning. Therefore, there are still many enterprises using vacuum hot water boilers. The vacuum hot water boilers of Zhengzhou Fangkuai Boiler Factory are divided into ordinary vacuum and condensing vacuum models. The two types of boilers have certain differences in operating efficiency. The operating efficiency of condensing vacuum hot water boilers is higher than that of ordinary vacuum hot water boilers. Around 5-8%, more cost-effective.
Many users who need to use vacuum hot water boilers attach great importance to the selection of boilers. The solution given by Zhengzhou Fangkuai Boiler Factory is that if you want to calculate the suitable tonnage vacuum hot water boiler for your own plant, you need to have a detailed understanding of the amount of hot water required by your own plant. Recently, a company asked Fangkuai Boiler about the need to purchase a vacuum hot water boiler, but did not know the specific tonnage. After calculating the data of the manufacturer, Fangkuai Boiler concluded that the plant used A 1400KW (that is, 2 tons) vacuum hot water boiler is enough. The market price of this model of vacuum hot water boiler ranges from RMB 180,000 to RMB 250,000.
We, Zhengzhou Fangkuai Boiler Co., Ltd. (Fangkuai), are excited to announce our participation in the Indonesia International Heating Technology Exhibition 2025.
