Low nitrogen condensing vacuum hot water boiler

Introduction

One unit can be equipped with multiple heat exchangers to supply hot water at different temperatures and for different uses, such as central air conditioning water, sanitary hot water, process hot water, etc. The company follows the principle of "maximum energy configuration" to ensure that each heat exchanger can achieve the maximum heat supply when providing heat alone, so that users can obtain the best results with the smallest investment.

Advantages

The heat exchanger of the vacuum hot water boiler is built-in, which saves a lot of auxiliary equipment investment and auxiliary equipment installation costs.
The auxiliary equipment is reduced and the floor space is reduced. The vacuum hot water boiler room can save 30%-50 % of the floor space compared with the traditional boiler room, saving investment.
It is not easy to scale, has no oxygen corrosion, and has a long service life. reaching more than 20 years, which is twice the service life of ordinary boilers.
Advanced control and fully automatic operation. One machine has multiple functions and flexible selection. The built-in stainless steel heat exchanger ensures water quality and can directly supply sanitary domestic hot water.
