Weishaupt - Model WL5–40 - Compact Oil Burners (56 to 1,945 MBTU/h)
The Weishaupt WL5–40 compact oil burners are a versatile and efficient solution for a range of heating applications. With capacities ranging from 56 to 1,945 MBTU/h, these burners are suitable for domestic, commercial, and thermal process applications where gas is not available. Designed with safety and reliability in mind, the WL5–40 burners incorporate advanced Low-NOx mixing assemblies to ensure clean combustion and comply with strict emissions standards. These burners can operate on standard oil, low-sulphur oil, and bio-oil blends up to B10 without any performance concerns. The compact design allows for easy installation and maintenance, reducing costs significantly. Key features include a sound-attenuated air inlet housing for quiet operation, a digital combustion manager with integrated connection console, and optional VSD and O2 trim for enhanced reliability and efficiency. Furthermore, the burners offer seamless integration with building management and automation systems, enabling remote control, monitoring, and fault diagnosis. This futureproof system solution guarantees excellent performance and long-term viability for various heating applications.
The Weishaupt WL5–WL40 burners cover a considerable capacity range up to 1,945 MBTU/h. Forced-draught oil burners are always the first choice when gas isn't available.
Highly reliable and safe, these burners are an ideal choice for domestic, commercial, and thermal process applications.
Excellent emissions
Weishaupt has also developed Low-NOx mixing assemblies for its oil burners. Of course, clean combustion has always been a focus, but – and this is crucial – key Weishaupt characteristics, such as reliable start behaviour, for example, or the same inspection intervals, also had to be maintained.
Modern fuels
Weishaupt oil and dual-fuel burners are generally suitable for oil and low-sulphur oil (#2 oil as per ASTM D396). Bio-oil blends up to B10 can also be used in the same way as standard oils without any need for concern – guaranteed
Universal application
The special matching of the flame geometry to the Heat generator 's combustion chamber is every Weishaupt burner's recipe for success. It allows customised use on different heat generators, such as air heaters or steam boilers.
Quiet operation
The air inlet housing is sound attenuated, which results in a noticible reduction in noise Emissions .
Perfect electrics
The Combustion manager 's integrated connection console and its coded and numerically labelled plugs leave no room for doubt. They enable components to be removed quickly, reduce maintenance work, and prevent connection errors. Simple and perfect!
The W-FM25 digital Combustion manager with its optional Modbus/ field bus module offers the possibility of communication with other systems, enabling the burner to be integrated with building management and other automation systems. Industry standards, like remote control, monitoring, and fault diagnosis, are well understood by Weishaupt.
