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 hot water boilers of the UNIMAT series are offered in various sizes and can operate 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.
Design:
The flame pipe ends with a rotating chamber of flue gases, washed by water, which passes into the second passage of the smoke pipes. In total, the boiler has three heat exchange passes: the first - in the boiler furnace (radiant heat exchange), the second and third - in the smoke tubes of the boiler (convective). The arrangement of smoke pipes in a circle ensures optimal flow of flue gases. Smoke pipes do not have internal turbulators, which 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 customer preferences, hinges can be located on the left or right. Thanks to the fully openable boiler door, complete maintenance, cleaning and inspection can be carried out. The absence of turbulators in the pipes of the second and third stroke reduces the labor intensity and time costs of carrying out routine maintenance maintenance boiler High-quality mineral wool surface insulation minimizes radiation losses. At the customer's request, the boiler can be equipped with a built-in or free-standing economizer, as well as a condensing heat exchanger.
