Efficiency    <>     Technology    <>      Application


EcoHORNET pellet burner heat and air generators incorporate advanced combustion technology, highly efficient heat exchanger, performance automation with web-based monitoring and control.

Hot and superheated ecoHORNET air generators are produced in the power range from 20 kWt to 600 kWt.

Their use improves the air quality in the beneficiary and considerably reduces the cost of thermal energy.

  • They are mobile, independent, compact.

  • They are produced in two ranges: for interior or exterior.

  • The air flow is inversely proportional to the temperature of the hot air produced.

  • They produce hot, superheated air at temperatures up to 700 ° C.


Green energy and savings of at least 50% of the thermal energy bill

For industry and agriculture or construction, the use of ecoHORNET hot air generators running on biomass pellets instead of fossil fuels significantly reduces energy and CO and particulate emissions.

The use of renewable energy in the activity of the company determines the increase in the energy efficiency of the whole company, the products manufactured have a competitive production cost, and the company improves its image brand in respect of the environment.


New ! In  all conditions. 

The new hot and superheated ecoHORNET air heaters operate outdoors in harsh climatic conditions: storm, blizzard, frost, down to -45 ° C.

ON-OFF operation: ecoHORNET hot air generators do not modulate, they operate at nominal power throughout their lifetime. The Start / Stop command is given by the room thermostat (if used for room heating) or the air temperature sensor for industrial applications.

100% Combustion

100% combustion control: The forced draft operation guarantees 100% control of the oxygen flow required for combustion, combustion is uniform throughout the mass of the pellet in the burner. Each pellet particle receives the oxygen necessary for complete combustion, so that the flue gases have a minimum content of particles, moisture or organic compounds.​.

Rendement 96-98%

The high efficiency of the air generator is kept constant throughout the life of the machine, both thanks to the design of the ecoHORNET burner, the combustion dynamics and the combustion control through full automation.

In addition, ash is collected outside the heat exchanger, without affecting its performance. The efficiency of the air generator does not depend on the raw material from which the pellets are made. The equipment is perfectly adaptable to all granulation raw materials, with the nominal power remaining constant. The constant high efficiency guarantees low fuel consumption.

100% Quality

100% quality materials: ecoHORNET equipment is designed for a long lifespan. The burner and combustion chamber are made of stainless steel which is specially resistant to high temperatures and temperature variations, and the heat exchanger is made of stainless steel and steel. All electrical and electronic components are made in the EU.

100% Safety

100% safety: Operational safety is guaranteed by a high-performance system that controls all the functions of the equipment.

Efficiency    <>     Technology    <>      Application



The patented ecoHORNET multi-system burner develops pellet combustion temperatures above 1250 ° C, all the calorific value of the fuel is recycled, transforming it into thermal energy. The combustion efficiency is close to 100%, the combustion is complete, without smoke in the combustion gases. The ecoHORNET burner is a mobile, self-cleaning and heating burner for the use of less energetic pellets. The burner and the combustion chamber are made of special stainless steel, resistant to temperatures above 1300 ° C and temperature variations. The ecoHORNET burner uses both pellets made from non-woody biomass and wood pellets.


Burner acceleration and grill cleaning system

The equipment has burner acceleration mechanisms to maintain rated output even if lower calorific pellets are used. So even if you use straw, grass, sewage sludge pellets, the equipment will produce the same amount of thermal energy as when you use wood pellets.


Speed ​​variator

The fan speed controller controls both the hot air flow and its temperature. The air flow is inversely proportional to the temperature of the hot air produced.



The fan carries the air through the heat exchanger. Hot air flow: 2500-56000 m³ / h depending on the power of the generator.



9. Automatic feeding system

The pellet feed is done automatically, with a transport screw driven by a capacitive sensor. SAFETY: The pellet feed system is equipped with safety devices to prevent damage if accidental foreign objects are entrained.

10. Ashtray

Unlike other solid fuel hot air generators, the ecoHORNET generator collects ash outside the heat exchanger. This is an advantage because a high build-up of ash does not reduce the surface area and the yield.

Optional: The high power hot air and superheat generators can be supplied with an automatic ash removal system and large capacity mobile ash storage.

11. Hot air exhaust

12. Pellet tank

Depending on the desired autonomy and the working space (indoor or outdoor), ecoHORNET hot air generators can be delivered with an integrated pellet tank or with a larger capacity pellet tank.


Heat exchanger

The heat exchanger has been specially designed to operate at high temperatures without wear over time and to ensure optimum energy transfer from the hot pellets.

For a larger replacement surface, part of the exchanger consists of finned tubes.

It is made of stainless steel and special steel, according to the latest regulations in force.

The heat exchanger efficiently transmits the energy produced by burning the pellets in the thermal agent, even if the boiler develops temperatures above 1250 ° C, the temperature of the flue gas at the outlet does not exceed 60-80 ° C. The difference in heat is transferred to the hot air. This translates into exceptional performance which, for the user, translates into low fuel consumption.


Desert Life

Complete automation with high-performance equipment and software developed in collaboration with the Austrian company SIGMATEK GmbH & Co. KG allows complete control of thermal energy production as well as all the systems that make up the installation and allows them to be integrated. in complex heating systems. The color touch screen will provide full information on the operation of the equipment. Equipment can be monitored and programmed remotely via an Internet connection, so you always have control of your heating system.



Smoke-free and tar-free combustion in the exhaust gases allows forced draft operation. The blower is mounted on the exhaust gases. The forced draft operation ensures 100% control of the oxygen flow required for combustion, combustion is uniform throughout the mass of the pellet in the burner, complete combustion including smoke particles.

Each pellet particle receives the oxygen necessary for complete combustion, so that the flue gases have a minimum content of particles, moisture or organic compounds. SAFETY: The exhaust of combustion gases is not influenced by atmospheric conditions.


Protection kit

Protection kit:

Due to electrical fluctuations / interruptions that may affect the electronic components of the boiler system or interfere with proper operation, we have included a standard protection kit: inverter with inverter, stabilizer, rectifier and 2 accumulators functions. In the event of an interruption in the power supply, the automation checks the opening of the safety hatch and the combustion gases do not pass through the exchanger, they are evacuated directly into the chimney by natural draft until the fuel is burnt from the grill.
