Burner sizes 50 - 70 (1,700 - 40,000 MBTU/h)

These versatile, large-capacity monobloc burners were designed especially for industial and energy-sector applications.


L50 oil burner RL50 oil burner RGL70 dual-fuel burner

These tried-and-tested gas, oil, and dual-fuel burners were designed especially for industial and energy-sector applications.

Versatility: The burners are rated between 1,700 and 40,000 MBTU/h and are suited for numerous applications, from hot-water and steam boilers to air heaters and various industrial applications. The industrial burners are available in a broad range of versions and can be operated using almost any gaseous or liquid fuel. Consequently Weishaupt can offer a suitable burner for almost any application.

Digital combustion management: Digital combustion management, with which this series is equipped as standard, provides economic control of the fuel and simplifies burner operation and maintenance. It also facilitates integration with various monitoring and controls systems, including complete building management systems.

Maintenance-friendly: The burner is well designed, with all components readily accessible. This simplifies servicing, and facilitatates a rapid recommissioning.

High quality: Select materials, decades of experience in Weishaupt's Research & Development Institute, and the latest production methods combine to reinforce Weishaupt burners'  global recognition as a top-quality product.

That's reliability: A comprehensive service and support network is available to customers, ensuring that combustion plant fitted with a Weishaupt burner always operates reliably.

Patented Weishaupt multiflam technology allows lower emission values on larger applications.

The core of this technology is a specially designed mixing head assembly, which provokes internal fluegas recirculation. Flame temperature is therefore lowered and generation of Nitrogen oxydes can be reduced. The NOx values are comparable to those typically reached by smaller compact burners.

Good Cost to Performance ratio: Additional external items such external flue gas recirculation system are only required, when compliance with market specific Ultra lowNOx values is required.

Optimum combustion: The mixing head assembly distributes fuel to multiple nozzles. Combustion process takes place via primary nozzle and secondary nozzles which are concentrically placed. The primary flame generates a stable, supporting flame for the entire firing range.

Allround purpose: Combined output rating for various Weishaupt multiflam burner series ranging from 340 to 78,500 MBH.

Digital combustion manager: The most modern technology controls fuel and air supplies and is also responsible for optimum combustion values.

Long Lifetime: Years long experiences and R&D works backup Weishaupt burner’s technology. Only the best materials are used for manufacturing.

Modern fuels: Weishaupt oil and dual fuel burners are generally compatible with light oil #2, low sulphur #2 light oil as well as #2 light oil with up to 10% bio content (B10).
