Kalorina serie 25 E

Versatility and technology: the future of environmentally friendly heating

The Kalorina K25 E Chips hot air generators are the result of years of research, work and specialized technical experience to provide a safe and innovative product able to guarantee an efficient heating solution, fast, with lower thermal inertia, several possibilities of use and considerable savings cost.

The Tatano generators from 151 kW to 1MW produce large quantities of hot air to spread it in large areas where it is not possible to set up a plumbing and are used both for heating the premises for civil and public use and for industrial heating.

They are ideal for heating large spaces such as workshops, warehouses, shopping centers, gyms, farms, greenhouses, industrial warehouses, but also as part of a drying system. They provide considerable comfort and an excellent alternative to the expensive traditional heating methods.

Innovative and versatile technological project

What distinguishes the Kalorina K25 E Chips hot air generators from traditional pellet and wood generators is the technology used that guarantees extreme versatility: it is possible to exploit different fuels in addition to the wood chips (pellets, shavings, sawdust) with feeding and functioning completely automatic, easy accessibility of the system for maintenance, great adaptability to the typical operating requirements with continuous power modulation, limited dimensions and overall dimensions.

The innovative construction and high build quality guarantee safe and simple use and long life. They consist of a new geometry combustion chamber equipped with an under-feed screw burner and horizontal heat exchanger built with special steels; the fire bed and the loading door are made of refractory cement resistant to high temperatures, for optimal combustion with high heat exchange.

The adoption of the insulating materials on the whole exchange body allows the perfect sealing of the hot air path, with high thermal-acoustic insulation. The generator is equipped with a removable drawer, on wheels, for the automatic collection of combustion ash.

By applying the two-stage combustion principle, with separately regulated primary and secondary air inflow, the required power and high yields with low emission values are guaranteed.

Simple operation and in total safety

Kalorina Series K25 E Wood Chips supplied as autonomous heating system is completely automated and this increases the comfort during use.

Its operation is based on a direct heat exchange system: the air to be heated is fed into the generator by double suction centrifugal fans and is externally lapped by the combustion chamber and the heat exchanger; in this way the energy produced by combustion is rapidly transferred, producing hot air, which becomes the means of conducting heat in the rooms.

The hot air produced exits in the upper part of the generator with minimal loss of load and a temperature drop of 40 ° C. It can be sent directly to the room or channeled through pipes to heat different spaces or to have a uniform heat distribution. The safety devices are highly technological: temperature probes, frequency inverters, thermostats and level sensors guarantee reliability and operational safety in every phase of operation.

Smart regulation for maximum comfort of use

All Kalorina Series K25 E hot air generators are supplied with a pre-wired electrical panel provided of a centralized regulation device fitted as standard. It is a digital modulating plant regulation, fully programmable according to the needs, which controls and optimizes the combustion process with the possibility of regulating power, temperature, depression, the residual oxygen content and the quantity of combustion air.

The graphic display with simple screens and intuitive menus allows the management and programming of all combustion parameters.

Brazier cleaning system

A careful cleaning around the brazier ensures an excellent combustion.

The system can be installed as an accessory in cases of use combustibles with a high ash content.

Depending on the size of the system, it is possible to combine the ash removal system of the combustion chamber with adjustable air injectors (already present as standard in some models) that automatically emit air jets and convey the ash towards the channels of collection which is taken from the extraction screws.

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.

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%.

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.

Exhaust gas deduster

The dust collector minimizes dust emissions by filtering the exhaust gases. Primary mono, bi- and multi-cyclone filtering systems are supplied completely separated or integrated on the boiler.

The dust collector is supplied complete with fan positioned on the sides or in the upper part, with electronic control and management. The integrated multi-cyclone on the boiler can be equipped with automatic removal of the fly ash by an auger and a star valve as an accessory.

The secondary filtration systems for the control of the particulate emissions of the wet scrubbers’ type are sized and designed according to the specific needs of the plant in the presence of problematic fuels, very dry and dusty

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.
