The reliability of the three-pass design of Unimat boilers has been repeatedly proven by examples of their practical application in 140 countries of the world. Fire tube boilers of the UNIMAT series are available in various sizes and can be operated in cascade.

Boilers of the UT-L type can be used in hospitals, private and multi-apartment residential buildings, office buildings, as well as industrial enterprises. Thanks to its high degree of versatility, the UT-L can be used as a backup boiler or used to cover peak loads.

The flame tube ends with a rotary flue gas chamber, washed by water, which passes into the second pass of the fire tubes. In total, the boiler has three heat exchange passes: the first - in the boiler furnace (radiant heat exchange), the second and third - in the fire tubes of the boiler (convective). The location of the fire tubes in a circle ensures the optimal mode of passage of flue gases. Smoke tubes 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 preferences of the customer, the hinges can be located on the left or right. Thanks to the fully opening door of the boiler, it is possible to carry out a complete maintenance, cleaning and revision. The absence of turbulators in the pipes of the second and third passes reduces the labor intensity and time spent on routine maintenance of the boiler. High quality mineral wool surface insulation minimizes radiative 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 liquid fuels. The use of condensing technology makes it possible to use the heat released during combustion as efficiently as possible, while reducing the harmful effect on environment. The block design and other configuration features make their use optimal for large facilities - industrial enterprises, hospitals, thermal power plants, factory floors.

Main advantages

• Bosch Unimat UT-L boilers are of traditional German quality, designed in accordance with TRD 300 standards, and are safe if the installation and operation rules are observed. Production in Russia provides absolute technical adaptation and the possibility of combining with the equipment used in the arrangement or modernization of the heat supply system.
• A wide range of power (650-19200 kW) and the possibility of choosing the design of the heat exchanger allow you to perfectly adapt the boiler to the parameters of the room and climatic conditions. It is possible to connect several boilers in parallel or in series to a single installation with a corresponding increase in power.
• Environmental friendliness with maximum heat transfer is achieved due to the principle of three-way passage of combustion products. Even when liquid fuels are used, emissions of harmful substances are kept to a minimum.
• The compact design and the lightweight alloys used make it easy to transport and install the boiler. At the request of the consumer, the front door and the burner can be hung on the right or left. The channel frame at the base of the boiler makes it possible to install without an additional foundation (if the boiler room has a flat floor).
• State-of-the-art engineering optimizes thermal stresses on the enclosure, increasing reliability and extending equipment life.
• Characterized by high efficiency due to the maximum reduction of probable heat losses and the use of latent heat of flue gases. The condensing technology achieves an efficiency of over 100%.

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