Features

AUTOMATIC CENTRAL HEATING STRAW PELLET BOILER FOR HOUSEHOLD USE!
Up to now, agripellet was used in high-output heating equipment, e.g. boiler rooms for residential development heating. Now you can use it in your own boiler room! The boiler can also be used in commercial applications.
 
ECONOMY AND CONVENIENCE
Straw pellet is available at an average price of 400 PLN/tonne. The device offers a convenient agripellet combustion in continuous mode (straw pellet, sunflower pellet), class A1, A2 and B wood pellet and biofuels (olive stones, hazelnut shells). It can also be used with manually stoked wood logs. Specially designed for customers abroad.
 
CERAMIC COMPOSITE INSERT
Ceramic composite insert with built-in secondary air duct for post-combustion of degassed fuel and reduced emission.

 

AUTOMATIC ASH REMOVAL AND AIR DUCT CLEANING
 The function significantly increases pellet combustion efficiency, reduces emission of toxic gases and dusts; self-cleaning of air ducts eliminates periodical shut-downs and manual cleaning. Patented in the Polish Patent Office.
 
PROGRAMMABLE CLEANING 
grate cleaning function can be programmed for different fuels. Cleaning start time and duration are automatically adjusted to the amount of fuel used and the heat output.
 
AUTOMATIC BOILER START-UP AND SHUT-DOWN
with a convenient automatic cleaning function.
 
WEATHER COMPENSATED CONTROL FOR FUEL EFFICIENCY
temperature sensors set the water temperature in the radiators based on the weather conditions (mixing valve).
 
INTERNET MODULE
all boiler functions can be remotely monitored using a PC or a smartphone (optional).

  AGROMATIC BURNER

AGROMATIC BURNER

High precision automatic air supply with a broadband oxygen sensor (optional) for up to 40% fuel use reduction.

 

Efficient fuel combustion in low-output domestic boilers. Up to now, agripellet was used in high-output heating equipment, e.g. boiler rooms for residential development heating.

 

Simplified operation for the highest comfort.

 

Considering the environment and your wallet, we have created a 2nd Generation Fuzzy Logic controller for high precision heat output control depending on the building’s heat demand. 

 

High precision automatic air supply with a broadband oxygen sensor provides up to 40% fuel use reduction (optional).

  OMS - Operating Monitoring System

OMS - Operating Monitoring System

Operating and monitoring system for solid fuel boilers. Our boilers are fitted with a system monitoring fuel level in the storage tank and the amount of ash in the ash pan to guarantee convenient and comfortable operation. In many boilers without a similar system available on the market user must remember to refill fuel and remove ash regularly. The system, developed by KOSTRZEWA, measures and notifies the user in advance on required actions (fuel refilling or ash removal). Notifications are displayed on a boiler controller screen and a room temperature controller screen. Our solution is patent protected.

  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.

PLATINUM BIO ECOMAX 860P 3 - S TOUCH CONTROL SYSTEM WITH COLOUR TOUCH CONTROL PANEL

PLATINUM BIO ECOMAX 860P 3 - S TOUCH CONTROL SYSTEM WITH COLOUR TOUCH CONTROL PANEL

An advanced device monitoring the combustion process in the boiler and the pellet burner.
System controls: fuel feeding from the storage tank, fuel feeder, pressure blower, igniter, DHW pump, fuel level sensor, boiler/buffer tank pump, buffer tank and two heating circuits with mixing valves, up to four auxiliary mixing valves - module B and C (optional).
 
Optional accessories: external temperature sensor, CH sensor, DHW sensor, return temperature sensor, colour ecoSTER TOUCH control panel with remote boiler control, programmable wireless 7-day thermostat, programmable wired 7-day thermostat, adjustable temperature sensor, EcoLAMBDA oxygen sensor, auxiliary extension module (B and C) and EcoNET internet module.

AGRIPELLET is a biomass fuel made of natural materials, usually straw or sunflower husks, without any added binders.

 

FUEL PARAMETERS:

  • size distribution 6±1 - 8±1 [mm]
  • length 3.15<L≤40 [mm]
  • recommended calorific value ≥15,000 [kJ/kg]
  • maximum ash content: 5%
  •  maximum moisture content ≤12%

 

AGRIPELLET! – eco-friendly, economical and clean fuel!

Ceramics is everywhere 

- the combustion chamber, the heat exchanger and the burner are coated with advanced ceramics to improve the combustion process and efficiency and to reduce the emission. During operation, the ceramics heats up to over 1,000°C to improve the biomass combustion efficiency.

 

Flue gas vortex generators retain energy inside the boiler.
