Hot water boiler VNTK

 

Use:

Hot water low emission boiler VNTK is designed for production of heating water with nominal working overpressure up to 0.6 MPa and temperature up to 110 ° C. It is designed for combustion of natural gas by low emission burners. The ideal solution is to use it as a standalone source or as a central heating unit for heating buildings for civil and industrial use. VNTK boilers allow flexible and fully automatic operation. With their connecting dimensions they replace the well-proven ČKD KDVE boilers and therefore do not require demanding installation. Their advantage is robust construction, high efficiency, simple installation and long reliability with a 5-year warranty. All this is supported by 24 hours service facilities in the Czech Republic.

Technical description:

The boiler body consists of two steel cylinders welded to the front and rear walls. The combustion chamber is cylindrical, water-cooled. The rear wall forms a flue gas turnover, which passes into the second draught and returns with the fire tubes back to the front wall into the third draught, which is formed by the openwork fire tubes. The explosion valve is on the rear wall. The front lid can be opened to the right or left according to the location in the boiler room. Allows easy access to heating surfaces and their cleaning. The boiler is insulated and plated with anodized sheet in blue color and equipped with all measuring instruments according to standards.

The boilers are supplied with a number of accessories such as: low emission burner, economizer, chimney, softening filters, etc.
