Who We Are ? Bidragon Group is engaged in manufacturing and exporting steam boiler, hot water boiler and thermal oil heater, during the past manufacturing process, our technical team reach and developed more than 10 patents for increasing boiler heating efficiency, Take thermal oil heater for example, out technical team design coil tube on boiler top and which design increases our thermal oil heater’s thermal efficiency higher more than two points than the common oil gas fired thermal oil heater, which technical update is highly appreciated by customer at home and oversea. What We Do ? We not only sell boiler, we are also committed to designing whole solution according to customer requirement, from hot water drinking of school, steam usage in laundry room of hospital, hotel heating solution, to thermal energy requirement of garment factory, etc., we have designed many whole solution for different customer, which projects now are working smoothly and is part of our honor. Why Choose Us ? 1. Patent technology: our factory has several patent technology, such as waste heat recovery patent, frequency conversion patent, corrugated furnace patent, etc. 2. Professional oversea sales team: all our sales in charge of oversea market has been trained professionally, they are familiar with our product and exporting formalities, which not only save time also save cost for customer. 3. Good service: no matter if you buy our product, when you find us, we would offer best service to you.
1. High heat efficiency, unique structure, the heat efficiency can be more than 78%.
2. Furnace radiation area adopts double square shaped coiler and on the top of boiler, we design the ceiling pipes, so that the heat load can be reduced on the surface of pipes and the thermal oil can work more safely.
3. In the end of boiler, we design a heating area with staggered arrangement. That will enhance the heat transfer coefficient and decrease the ash deposit in the boiler.
4. The unique design of furnace arch with our own patent can make the coal burn out fully to enhance the heat efficiency.
