Safe Reliable Oil Fired Hot Water Boiler Energy-Saving Heating

Automatic WNS boiler is a kind of horizontal, three-pass, wet back, fire tube boiler. Wet back means the back of furnace is surrounded by water, then the temperature of tube plate will be much lower. Normally the rated capacity of WNS series boiler is less than or equal to 20tons and rating pressure is less than 2.0MPa.

Advantages of oil fired energy-saving hot water boiler

1. Adopt the latest international technology of big volume combustion design and deploy world famous burner, making the boiler has more fully burning, higher efficiency and lower failure rate.
2. Adopt the advanced structure of corrugated furnace. On one hand, it increases the heat-transfer area. On the other hand, it can bear the free expansion of furnace after heating.
3. Adopt thread smoke tube, which can enhance heat-transfer and eliminate welding stress.
4. Adopt double seal structure with the back of inner seal surrounded by water, which makes the boiler more reliable and maintenance costs lower.
5. Double door design, it is very convenient for checking and maintainace.
6. All kinds of protective functions, such as over-temperature, over-pressure, water shortage, leak checking, flame-out and so on,ensuring safe and reliable operation of boiler.

Transportation & Deivery

1. Nude packaging for boiler main part and wood box packaging for boiler accessories.
2. Generally use 20 container, 40container or 20 flat rack container and 40 flat rack container to load the boiler.
3. All goods will be fixed after packing into containers.
4. We have stable shipping company to cooperate for long term. They will confirm the safety of the goods.
5. Shipping way is different according to customer's country. Mostly by sea. Some country by train.
