Advanced design

WNS series of hot water boiler is three return all wet back structure .100% completely butt welding, mini stress and reliable quality.Compact structure makes the installation is easy, and also can reduce the cost for Boiler room construction.

Safe and reliable

The corrugated furnace and large burning room make it have good thermal flexibility.

.

Enough heating room

Furnace big, high radiate, three return design, combustion air is full, high-efficiency heating surface. Using high thermal resistance of insulation materials, boilers, heat losses to the minimum.

High efficiency

with threaded pipe and high effective insulation materials, increasing the heat transfer and improve boiler thermal efficiency. Boiler thermal efficiency is more than 93%.

Digital control system

PLC control system,Intelligent, automatically control, with automatic temperature regulation, over-temperature standby.
