Equipped for the future: H2-ready

The gas condensing boiler is already suitable and certified for operation with up to 20% hydrogen and biomethane.

Superb heat transfer and constant high efficiency during its entire lifecycle

TRIGON® XL designed for challenging environments. Its advanced burner design makes TRIGON® XL the most technologically advanced and best performing unit on the market. In combination with a robust and corrosion free stainless steel heat exchanger built for challenging working conditions. It is offering superb heat transfer and constant high efficiencies of up to 110% during its entire lifecycle. Stainless steel laser welded fin tubes made by advanced robot laser welding technology minimise heat losses between tube and fin. This guarantees the highest possible heat transfer from the extended heat exchanger surface vs. plain tubes.

Description of the TRIGON XL premix burner system

Unique premix-burner system

A fully modulating, watercooled cold flame burner utilises a one-of-a-kind technology to provide reliable and robust performance.

Low emissions

The watercooled cold flame burner and the optimised combustion zone achieve extremely low NOx and CO emissions, which already comply with NOx class 6 requirements.
Lifetime high efficiency

By combining the unique premix-burner/heat exchanger system with the optimised controls, TRIGON® XL provides impressive lifetime high efficiencies of up to 110 %.
Stainless steel laser welded fin tube

Advanced robot laser welded technology minimises heat losses between tube and fin, guaranteeing superb heat transfer from the extended heat exchanger surface.

Water cooled combustion chamber

A carefully engineered hydroforming process fixes the cooling tubes inside the sidewalls, providing the highest possible thermal output.

Unique smart modular concept

With TRIGON® XL’s smart modular concept the boiler can be disassembled for easy on site handling. This also allows the boiler to be easily installed into buildings with restricted access. In combination with its lightweight construction the boiler fits perfectly into rooftop installations.

Fast installation

The total time for disassembly and assembly takes a maximum of 0.5 working days.

Description of the easy transport of the TRIGON XL

Easy transportation and set up

The boiler is supplied with cargo wheels, which allows easy on site maneuvering. After positioning, the boiler can be levelled and lifted from the wheels by adjusting the feet.

Compact dimensions

The range comprises 7 models with 2 widths which are designed to pass through standard 760 mm wide doors.

Flexible configurations

The inspection glass and ignition electrode can be fitted on either side of the boiler, allowing a more flexible boiler positioning on site.

Simple commissioning

An integrated flue gas damper and rear flue connection provides an installer-friendly arrangement.

Extraordinary flexibility

TRIGON® XL’s stunning flexibility sets a new standard for commercial applications. An 8 bar maximum water pressure and 30 K flow/return temperature differential allows easy integration in complex systems, both in single and cascade applications.

Performance classes

The TRIGON® XL boiler range comprises 7 models in outputs from 150 kW to 570 kW.
