Pellet boiler NBE-RTB (10-80 kW)

Pellet boilers NBE-RTB
RTB is the latest generation of pellet boilers that require as little care as heat pumps, gas heating or heating with liquid fuels. All that is needed is a refill of the pellets in the hopper and a few scrapes of the ash box. Boiler cleaning, monitoring of the combustion process will be carried out by the boiler automation.
The entire RTB boiler production and development process takes place in Denmark at the NBE (NordjyskBioenergi) plant. NBE products have a market share of 60-70% in Denmark and around 10% of the total European market for pellet boilers.
- Efficiency class 5
- Power range 10-80 kW
- Automatic cleaning
- Remote control
- Safe and reliable in operation
- Cleaning with compressed air is efficient and maintenance-free. This cleaning is usually used in heavy duty boilers.
- The burner is cleaned with compressed air and the combustion zone itself is made of non-corrosive steel.
- A flue gas fan modulates the required draft for optimum combustion.
- Low water content in the boiler for faster heating and more economical summer operation.
- Lower installation costs, as many things are already built in and tested in the factory
- Modern look with communications hidden in the housing
- Easily adjustable operating process
- The pellet and ash box level gauges will give a message when the pellets need refilling or the ash box needs cleaning.
- Boiler combustion chamber vacuum gauge.There will be no smoke in the boiler room, the boiler will shut down if the chimney does not have sufficient draft.Boiler cleaning once per heating season, boiler control using high pressure air jets to clean the boiler heat exchanger and burner of deposits.
- You can fire 3 tonnes of pellets before you need to empty the ash container because of the compression technology in the external container
- Optimised flue gas flow and sealed boiler body reduce the risk of condensation in the chimneyHigh efficiencyLow heat loss from the boiler because the combustion chamber is designed so that the highest temperature is in the middle of the boiler (mid-combustion), after which the flue gases flow to the outside of the boiler.The ability to operate the boiler at low heating water temperatures of up to 40 degrees, which reduces heat loss in the heat paths.The very tightly insulated casing eliminates the possibility of flue gases entering the room, there is no smell of flue gases.If you need to heat larger areas, you can cascade up to 8 boilers and get up to 640kW
- Extended warranty up to 10 years.Control of 4 heating circuits and hot water.
- Manufacturer: Denmark
Energy efficiency class: A+
