Kalorina serie 25 E

Industrial hot air generators

Kalorina Series K25 Chips industrial hot air generators are innovative and safe heating systems. They guarantee high performance in the production of high quantity of hot air to be spread in large areas and when it is not possible to provide a hydraulic system; they are able to guarantee an efficient and fast heating, with less thermal inertia and various possibilities of use.

Series K25 E responds to the most requests for localized or non-continuous heating for large companies and industrial environments of different nature; the generators of the series are versatile and efficient, guarantee great reliability of operation to the typical operating needs and adapt to any changes in the system or the working environment.

The Tatano brand industrial hot air generators can be automatically fed with different types of fuels, sawdust, wood chips, pellets, energy grain; they are ideal for heating workshops, warehouses, shopping centers, gyms, greenhouses, farms, industrial warehouses, but also as part of a drying, ventilation or air conditioning system, creating summer or winter conditioning units.



  • Each generator is independent and autonomous, allows you to heat where and when you need it.
  • The air heating does not require the construction of the traditional thermal power plant and avoids expensive pipelines, sources of heat loss (and not recoverable in case of moving)
  • They adapt easily to changes, displacements or extensions of the system
  • With the hot air operation, even the largest rooms are easily heated, thanks to the low thermal inertia and the absence of freezing carrier fluid.
  • They require minimum maintenance costs thanks to the completely automatic ash removal and the optional pneumatic cleaning system
  • The use of biomass fuels allows for lower operating costs, with a high seasonal yield of up to 92% and in compliance with emission values

Innovative and versatile technological project

What distinguishes the Kalorina K25 E Chips industrial hot air generators from traditional pellet and wood generators is the technology used that guarantees extreme versatility: fully automatic feeding and operation, easy access to the system for maintenance, great adaptability to the typical functioning requirements and continuous power modulation, limited overall dimensions. In addition, the generators can be fed not only with wood chips, but also with pellets, shavings or sawdust.

Built with high quality materials, they have been designed to achieve long life and high yields; they consist of a combustion chamber with new geometry, equipped with an under-feed burner, horizontal heat exchanger made of special steels, the fire bed and the refractory cement loading door resistant to high temperatures for optimal combustion and high heat exchange.

The use of insulating materials for all the 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.

With the three-stage combustion principle (primary, secondary and tertiary air flow, regulated separately by inverter) in combination with the regulation of residual oxygen content (Lambda probe) the required power, a high efficiency, a lower fuel consumption and reduced emissions are guaranteed, even at partial load.

Simple and safe functioning

Kalorina K25 E Wood Chips used as a heating system is completely automated and this increases the comfort during use.

Its operation is based on a direct heat exchange system in which 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: the energy produced by combustion is so quickly 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 pressure losses and a temperature drop of 40 ° C. It can be introduced directly or ducted through pipes to heat different environments or to have a uniform heat distribution.

The safety devices are highly technological: temperature probes, frequency inverters, thermostats, 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 with a centralized regulation device fitted as standard. This is a digital modulating regulation, completely programmable according to requirements, to control and optimize the combustion process, with the possibility of regulating power, temperature, depression, the residual oxygen content and the quantity of combustion air.

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.
