Multifuel boiler Domusa BioClass NG 43

The boiler Domusa BioClass NG 43 is a multifuel biomass boiler of 43 kW that can burn pellets and crushed olive bones. This boiler has electronic modulation, automatic cleaning with system Grinder and a choice between reservoirs 195 and 350 kg.

Domusa has achieved a technologically advanced product, obtained in the process of certification, the highest possible rating in Europe (Class 5 according to standard EN303-5) in all matters related to performance (up 95%), security and low emissions of gases and dust into the atmosphere.

Possibility of using various types of biomass pellets (pellets and olive stones) so that the user decide which is the best option that suits your needs and/or opportunities.

For burning olive pits has to include the kit that you can choose where to above under the price figure.

This boiler does not include any deposit to save the pellet or olive bones, and therefore you have to choose one of the two listed below in the section on Accessories. Have a capacity of 300L/195kg or de 544L/350kg respectively.

Exchanger cleaning system and fully automatic burner, which provides high user comfort and convenience. Cleaning the burner (Grinder system) is specially designed to treat ash and unburned (silica) high strength, to ensure both durability and low maintenance of equipment.

Automatic Fuel Operation
Biomass pellets allow automatic operation of boilers for heating and hot water. The boilers that use this type of fuel can be automatically started without user action and allow fuel use automatic feeders.

Saving
With BioClass NG boiler fuel consumption is reduced recovering investment in a short time. This is based on two aspects.

Efficiency
The body design of the boiler and their flues is designed for gases cede most of their energy to heat transfer fluid from the hip, and consequently the installation. The boiler BioClass NG able to reduce significantly the temperature of the flue gas, thus achieving the best market returns by category.

Modulation
BioClass NG boiler has an electronic control which controls the amount of air required depending on the amount of fuel is provided, so as to achieve the required temperature in the boiler body. This allows superb combustion characteristics even with reduced powers. Being able to work with a system of reduced power are achieved significant savings in consumption, as the boiler output is adjusted to the needs of the facility. By having a wide range of modulation and able to work at low power cycles on / off boiler, avoiding lost in stopping and can be installed even without buffer tank is reduced.

Electronic Control
BioClass NG boiler has an electronic control that facilitates installation, by having multiple connection solutions for different system components. This control can perform installations with several areas including control over these areas with room thermostats or optional environment sensors. This control is designed so that you can implement modules that can command different types of installation. Also allows connection to a vacuum system automatic load and power commands telephone.

Direct return
The boiler BioClass NG features an innovative system that prevents return preheating complicated mixing systems to prevent condensation that can occur as a result of cold returns the installation. This system supports direct preheating boiler up to 25 ° C returns, which allows direct facilities, with any type of hydraulic installation settings.

Automatic cleaning
Cleaning of this boiler is fully automatic. Has a set of turbulators further step of retaining the fumes, in order to improve performance, is responsible for cleaning of ash remains in the hot gas. These turbulators are attached to the shaft of a motor via a cam system which periodically cause a vertical movement, thereby cleaning the gas flues.

Grinder system
The burner has an automatic cleaning system ashes. The lower body on burner features a patented cleaning system that periodically takes care of sending the ash generated in the combustion ashtray. The Grinder system makes cleaning even with the burner running, allowing not alter the comfort of installation, cleaning needs that may occur on the burner and leverages all the fuel supplied to the combustion chamber.

Reservation deposits manual loading
BioClass NG boiler is equipped with a host of primary power and can incorporate different deposit reserve capacities manual loading. The reserve deposits are delivered fully assembled and have a built grid load.

Deposits are not included with the boiler, so you have to choose one of the two listed below in the section on Accessories.

There are two capacities:

• Booking deposit NG S 300 L / 195 kg.
• Booking deposit NG L to 544 L / 350 kg.
