Air heater
Heavy-duty forced-air boiler generating hot air for heating large buildings in a water-free heating system. Perfect solution for heating shop floors, storage and inventory areas, sports facilities (artificial turf sports fields, tennis courts) and greenhouses. The heated air can be distributed via a system of ducts or directly from the air heater. Forced-air heating system is a real alternative to conventional water heating systems - it is more cost efficient and eliminates the risk of freezing.

We are a sole manufacturer of advanced forced-air boilers in Poland - dynamic and fuel efficient heating of available building volume. Our forced-air heaters are the most advanced products on the European market. The air heaters can be combined with ventilation and cooling systems.

Benefits

AUTOMATIC OPERATION AND CLEANING

The buildings can be automatically heated with air with full control and programming via the Internet. Automatic burner, ash pan cleaning, output adjustment based on outdoor and indoor temperatures provide comfortable use and conditions in the building.


LOW PELLET AND ENERGY CONSUMPTION

Many buildings require periodical or time-based heating - our forced-air heating systems can be used as and when necessary. Any area can be heated from 0°C to several degrees Celsius in less than an hour. The transfer of heat to the surrounding area is practically immediate and does not generate any losses for heating and distribution of large volumes of water. The system also eliminates risk of freezing. Our forced-air systems feature microprocessor-controlled fans and offer very low energy consumption.

 

MANY YEARS OF TROUBLE-FREE OPERATION

The quality of materials used guarantee many years of operation at the highest efficiency. Every single component is carefully selected by the KOSTRZEWA design department. The majority of system components is manufactured by KOSTRZEWA.

 

ROBUST DESIGN

In modern production of heating devices, the key factors include automation and repeatability of production processes and high quality of steel and construction methods used. The air heaters can reach air temperatures up to 70°C without any deterioration in quality.

 

SELF-CLEANING BURNER

Innovative rotary PLATINUM BIO SPIN burner guarantees maintenance-free combustion of class A1, A2 and B wood pellet. The technology used allows to purchase pellet 50% cheaper than pellet available for users of other forced-air heating systems that usually require more expensive class A1 fuels.


A COMPLETE HEAT SOLUTION

We offer comprehensive heating solutions for any building, including our pellet storage systems, pneumatic pellet feeders, cascade control systems, weather compensation, fuel and ash level sensors. Forced-air heating can operate in a closed loop, mixing the warm air inside the building with the fresh outside air.

  Pellets Air Heater – How to Heat Large Spaces Cheaply and Effectively

Pellets Air Heater – How to Heat Large Spaces Cheaply and Effectively

KOSTRZEWA's forced-air heating system is an innovative solution designed for various types of large-volume buildings, such as production halls, warehouses, sports facilities, and other spaces requiring efficient heating. An example is an industrial hall, where we demonstrate how to achieve an economical and effective solution for heating large areas.

The core element of this system is the Pellets Air heater, which offers a range of advantages.

AGROMATIC BURNER (applies to model: Pellets Air 30)

AGROMATIC BURNER (applies to model: Pellets Air 30)

Intended for combustion of agripellet (straw pellet, sunflower husk pellet) in continuous mode and wood pellet for domestic and commercial use, class B, A1 and A2 pellet and biofuels (olive stones, hazelnut shells). 

PLATINUM BIO SPIN BURNER (applies to models: Pellets Air 50, 100, 200)

PLATINUM BIO SPIN BURNER (applies to models: Pellets Air 50, 100, 200)

An innovative burner with a rotating combustion chamber for granulated biomass fuels with ash content up to 2% (pellet class A1, A2, B); patented at the Patent Office of the Republic of Poland. 2nd generation Fuzzy Logic controller and two-section menu for reduced fuel consumption by up to 20% and reduced component wear compared to other available burners (reduced number of burner start-ups significantly reduces the amount of energy used). Burner cleaning has never been this easy - mechanical cleaning of the combustion chamber through the rotation of Platinum Bio SPIN’s grate. The rotation frequency is programmed to remove excessive ash depending on the fuel used to reduce burner shutdowns interval from 3 days to about 2 weeks (depending on the ash content of the fuel).

  PELLETS VACUUM (PNEUMATIC PELLET FEEDER)

PELLETS VACUUM (PNEUMATIC PELLET FEEDER)

A virtually maintenance-free pneumatic device feeding pellet at a large distance from the storage area directly to the boiler including multiple sensors for a fully automatic operation.  If MINIMUM level is detected in the buffer tank, it is immediately refilled to the MAXIMUM level. The device can also be timer programmed, i.e. the buffer tank will be refilled to the MAXIMUM level at a pre-set date and time.
