The hot water low-temperature boiler VNTK is designed for production of heating water with a nominal working overpressure up to 0.6/1MPa and temperature up to 110°C. It is designed for combustion of natural gas, diesel and light fuel oil. 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 alow flexible and fully automatic operation. They were developed to replace some well-proven ČKD KDVE and BK boilers, taking into account today's requirements for efficiency and low emission values. Their advantage is robust construction, high efficiency, simple installation, simple maintenance and repairability, long reliability with a 5-year warranty. All this is supported by a 24-hour service background in the Czech Republic.
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 through the fire tubes back to the front wall, where it turns into the third draught, which is formed by the openwork fire tubes. The front lid can be opened to the right or to the left depending on the location in the boiler room. It allows easy access to heating surfaces and their cleaning. The boiler is insulated and plated with blue anodized sheet and equipped with all measuring devices according to standards.
Upon request, the boiler can be supplied as an aggregate from the manufacturing plant with a burner, fittings and boiler automation, etc.
