Use
The Dory 40 warm air and radiant heaters are designed for heating and supplementary heating of a wide range of spaces, including workshops, storage rooms, industrial buildings, construction sites, residential areas, guesthouses, restaurants, halls, clubrooms, and recreational facilities. They provide an ideal solution for efficient heating of various types of buildings.
Fuel
The Dory 40 heaters allow for the burning of wood or wood briquettes, offering flexibility in fuel selection.
Thoughtful Design and Rapid Heat Distribution
The Dory 40 heaters feature a well-designed construction with a warm air heat exchanger and a radial fan that effectively blows hot air. Thanks to the CB secondary combustion system, they achieve very high efficiency.
- Warm Air Heat Exchanger: Efficiently extracts heat from the exhaust gases, significantly reducing heating costs. The heat exchanger includes a scraper element for easy cleaning of the heat transfer surfaces, ensuring long-term efficiency and proper function.
- Rapid Heat Distribution: After a short warm-up time, the fan quickly distributes warm air throughout the room. The fan is positioned at the lower rear of the heater to minimize the risk of damage during a power outage.
Clean Combustion
The Dory 40 heaters are equipped with a combustion chamber lined with durable refractory bricks, which maintain high temperatures in the combustion chamber and contribute to complete combustion. The two-chamber CB secondary combustion system meets the strictest European emission standards.
- Low Emissions and Fuel Savings: The heaters produce very low emissions and have up to 40% lower fuel consumption compared to conventional heaters of similar performance. The refractory bricks also protect the internal metal parts of the combustion chamber from high temperatures, significantly extending their lifespan.
Easy Performance Regulation
The heater’s performance can be easily regulated through the primary air supply using a controllable damper in the door. Primary and secondary air are optimally set from the factory.
- Control Unit: An optional control unit for regulating the fan speed, which blows hot air from the heater, can be purchased separately. The unit can operate in automatic or manual mode. In automatic mode, the fan speeds are adjusted based on the current performance (temperature) of the heater.
