Condensing Hot Water Boiler

Introduction

Model specification and Configuration Illustration

Boiler Type: CWNS

The instruction of Mainfold equipment configuration: configurate the number of tube socket of output and input according to the workshop's requirement

Rated Power:0.7-14MW

The instruction of water treatment device's configuration: configure water treatment device' according to the hardness of water

Rated Pressure:0-2.5MPa

Fuel choice instruction:Choose natural gas, city gas, liquefied gas or biogas depend on the needs of customer

Unique Orientation
The first choice of Energy-saving boiler

CWNS series condenser gas fired hot water boiler adopts shell corrugated furnace structure,smoke three-pass design,wet back structure of reversal chamber,spirally corrugated tube. A condenser placed in the tail of the boiler absorbs waste heat of smoke to reduce discharged smoke temperature to 60℃.The boiler matched with gun burner,packaged with square embossed aluminum sheet,elegant look, with mature technology,stable and safe operation and high heat efficiency.
