The flame tube ends with a rotary chamber of flue gases washed by water, which passes into the second course of the smoke tubes. In total, the boiler has three heat exchange strokes: the first - in the boiler furnace (radiant heat exchange), the second and third - in the boiler smoke tubes (convective). The arrangement of the smoke tubes in a circle ensures the optimal flow of the flue gases. Flue pipes do not have internal turbulators that create additional resistance to the movement of combustion products. The combustion chamber, water space, radiant and convective heating surfaces are optimized and mutually coordinated.

The front door of the boiler opens completely. Depending on the customer's preference, the hinges can be located on the left or right. Thanks to the fully opening boiler door, it is possible to carry out complete maintenance, cleaning and revisions. The absence of turbulators in the pipes of the second and third stroke reduces the labor intensity and time spent on carrying out routine maintenance on maintenance boiler. High quality mineral wool surface insulation minimizes radiation losses. At the request of the customer, the boiler can be equipped with a built-in or free-standing economizer, as well as a condensing heat exchanger.

Universal heating boilers Bosch Unimat UT-L are designed to operate on gas and light fuel oil. The use of condensation technology allows you to use the heat released during combustion as efficiently as possible, while reducing the harmful effect on environment... The modular design and other configuration features make their use optimal for large facilities - industrial enterprises, hospitals, thermal power plants, factory workshops.

Main advantages

• Bosch Unimat UT-L boilers have traditional German quality, are designed in accordance with TRD 300 standards, and are safe if installation and operation are followed. Manufacturing in Russia provides absolute technical adaptation and the ability to combine with the equipment used in the arrangement or modernization of the heat supply system.
• A wide power range (650-19200 kW) and a choice of heat exchanger design make it possible to perfectly adapt the boiler to the parameters of the room and climatic conditions. Parallel or series connection of several boilers into a single installation is possible with a corresponding increase in power.
• Environmental friendliness with maximum heat transfer is achieved thanks to the principle of three-pass passage of combustion products. Even when using liquid fuels, emissions of harmful substances are minimized.
• The compact design and the lightweight alloys used simplify the transportation and installation of the boiler. At the request of the consumer, the front door and the burner can be hung on the right or left. A channel frame at the base of the boiler makes installation possible without an additional foundation (if the boiler room has a flat floor).
• State-of-the-art engineering designs optimize chassis thermal loads, increasing reliability and extending equipment life.
• High efficiency is characteristic due to the limiting reduction of probable heat losses and the use of latent heat of flue gases. Condensing technology achieves efficiency in excess of 100%.

Bosch Unimat UT-L boilers combine excellent specifications with ease of maintenance. The design provides for the accessibility of the combustion chamber and additional heating surfaces, easy cleaning, the ability to inspect the reversing chamber. Additional comfort is provided by individual selection of the configuration.

For ease of operation, a coordinated control system for the heating circuit, boiler and burner is used, depending on user requirements and design, adapted to various software applications. The use of the CMC-930 functional module allows you to control an installation that includes up to 8 boilers with general or separate coordination of the operation of each of them.

Design overview

Boilers Bosch Unimat UT-L different models designed to burn natural gas or liquid fuel in accordance with the standard for the production of low pressure coolant. The versatility of use is achieved by the ability to complete construction modules and optional equipment according to the needs of the user.
