Essential information

The GRAND PELLET boiler is the ideal solution for very large enterprises and production halls. The boiler is designed for efficient burning of wood pellets in accordance with the norm 303-5:2021-09. It is equipped with a self-cleaning burner and a comprehensive self-cleaning system for the heat exchanger. The pellet igniter, in collaboration with an RTC clock, ignites and extinguishes the boiler according to a schedule, reducing the amount of tasks required to operate the boiler to almost zero. Thanks to the included ecoNET300 internet module, you can manage the boiler’s functions from your phone, tablet, or computer.

Key benefits

Z

Heat exchanger

Horizontal convection channels | tubular
Effective structure adapted to automatic cleaning of the exchanger. The design of the boiler exchanger ensures high heat removal from the furnace.
Z

Flue outlet

At the back of the boiler
The structure of the boiler has been designed in such a way that the flue outlet is at the rear. The use of such a solution in a central heating boiler allows the flue to be directly led out to the chimney.
Z

Limit switch

For the sake of your safety, the boiler is equipped with a limit switch. The end protection system is located in the boiler door. Each door opening automatically stops the operation of the burner and other elements of the boiler until they are closed again.
Z

Exhaust fan

Adjustable height
The exhaust fan effectively supports the natural flue gas draft in the boiler.
Z

Steel screens

The use of steel screens in the combustion chamber improves the efficiency of the combustion process. The screens increase the temperature in the combustion chamber and stop the particles floating above the furnace, burning them up. The thermal efficiency of the boiler increases, and the flue gas has a reduced amount of compounds harmful to the environment to a minimum.
Z

Automatic feeder

The PLATINUM PELLET controller, based on the information received from the sensors, determines the demand for fuel and doses it the right amount. The process of fuel combustion itself is therefore very economical, ecological and does not require additional service on the part of the user.
Z

Automatic ash removal system

Accessories

The process of automatic ash removal consists in pushing the ash outside the boiler, into two specially designed containers. Both containers for collecting ash have wheels and a handle, thanks to which you can efficiently pull or lift them.

Z

Swirlers

Combined with automatic cleaning of convection channels
Swirlers installed in the convection channels, connected with the automatic cleaning system, effectively reduce the speed of the exhaust gas outlet. Thanks to systematic cleaning, the boiler maintains a constant high heat consumption through the water jacket. The use of automatic cleaning of convection channels contributes to the reduction of fuel consumption.

Boiler control

Adjust the boiler operation and room temperature to your individual needs. The PLATINUM PELLET controller is programmed in such a way as to automate all processes related to the heating of your home. The owner specifies the temperature he wants to have in the apartment, and the controller will optimize combustion in this respect. Entering the advanced driver settings, you can personalize each parameter. It all depends on the preferences of the user and household members!

Pellet burner

Self-cleaning PPW burner – for pellets

Quick firing up of the furnace and automatic cleaning of the furnace of ash. The burner is equipped with two automatic ceramic pellet igniters and has been designed for regular, automatic cleaning of ash. The design of the burner allows you to quickly reach a high temperature of the boiler. All functions of cleaning the furnace from ash and fuel dosage can be set in accordance with the current needs of the user.

Key features:

E
Fuel: Pellet
Ecological fuel such as pellets, also known as biomass, is produced by pressing wood waste such as sawdust or shavings. This completely natural fuel turns into biodegradable ash after burning.
E
Two ceramic pellet igniters
Forget about manual boiler lighting. One click is enough and the automatic ceramic igniter ignites the fuel fed to the burner. Automatic igniter in conjunction with the RTC clock allows you to program the entire week of operation of the device. The device operation clock can be set separately for SUMMER and WINTER mode.
E
Automatic cleaning
The burner is cleaned of ash on its own on a regular basis, which reduces the need for manual cleaning to a minimum. The use of this technology prevents clogging of the furnace chamber with ash, and also allows the burner to be kept in excellent efficiency.
