High efficiency with Low - NOx combustion technology

The Tatano medium power boilers offer the possibility of using different types of fuels, with low emissions, thanks to the technologies used.

The geometry of the combustion chamber was developed by applying the fundamental fluid-dynamic principles, able to operate a subdivision of the primary air, in order to reduce NOx emissions; it is covered in refractory material with a high content of alumina and guarantees a high resistance with minimal heat loss thanks to its complete insulation.

The automatic cleaning of the exchange surfaces and the combustion chamber with screw discharge in the special ash box constantly keeps the yields high with minimum consumption. The automatic ignition and the autonomous maintenance of the flames require the minimum use of energy with maximum operating safety. The technologies used offer great autonomy of the system thanks to the wide range of accessories for storage and fuel sampling.

Maximum respect for the environment

The boilers are characterized by a low content of particulates in the exhaust gas thanks to the integrated multi-cyclone filter complete with smokes extractor, which allows to maintain the correct depression inside the combustion chamber.

Moreover, this process is made more effective thanks to the double control of combustion through the temperature probes (water/smokes), in combination with the regulation of residual oxygen content (Lambda probe) with minimum emissions even at partial load, which allows to access various forms of state incentives.

Touch controller easy to use

The Kalorina LE boiler features integrated digital electronic control with touch display and simplified navigation through the intuitive menu that allows you to regulate power, combustion temperature, depression, residual oxygen content and combustion air quantity in a wide modulation range ( 1: 4) of the power, for an optimal adaptation of the system to the actual needs.

Remote access via PC, tablet or smartphone allows remote monitoring and control of the system, as well as access to the full range of after-sales service

Pneumatic cleaning system

A clean heat exchanger is crucial for ensuring the efficiency and life span of a boiler.

The pneumatic cleaning system eliminates the ashes in the exchanger through short compressed air blows at regular intervals and which propagates with a shock wave along the tubes, cleaning the walls from the deposited particles.

In this way maintenance interventions are significantly reduced

Economizer for heat recovery from smokes

A part of the exhaust gas with a reduced oxygen content returns to the combustion chamber.

Thanks to the mixture with the primary air it guarantees the complete gasification of the fuel, it allows to lower the temperature of the combustion chamber, to reduce the particulate emissions and ensure a long life of the combustion system.

The yield is improved of about 3-7%.

Automatic ash removal

Centralized or separate automatic removal of ash from the combustion grid or multi-cyclone. In the centralized variant the mechanical removal by hydraulic rakes or extraction screws conveys the ash from the combustion grid and from the multicyclone to an external common container. In the separate variant, the ash from the combustion grid and the multi-cyclone is transported in separate containers.

Exhaust gas recirculation

In the presence of problematic fuels, it is possible to install an exhaust gas recirculation device, to reduce the temperature of the combustion chamber and lower the thermal NOx:

  • With fuels with a low ash melting point
  • With dry fuels with a high calorific value

In this way a high yield is guaranteed respecting the plant and without the formation of waste.

Remote Control

The app 4 heat offers new possibilities for controlling and managing the remote heating system via internet routers (Wi-Fi) and the Cloud server.

If the boiler setting is connected to the internet, all the heating settings can be viewed and changed directly from the smartphone, tablet or PC. In this way, it is possible to have the heating under control wherever you are.

In addition, the remote access solution allows access to the full range of services offered by the Tatano technical assistance service.
