ENDURA XE Condensing Hydronic Boiler

ENDURA XE Condensing Hydronic Boiler

(117kW to 219kW)

Hundreds of thousands of installations around the world rely on Fulton’s legendary rugged, robust and reliable condensing boilers. Like all Fulton products, the ENDURA XE is built to last and delivers leading-edge efficiencies and utility savings.

Reduce Fuel Costs & Emissions

The ultra-high efficiency heat exchanger and fuel-saving burner reduce fossil fuel use by 15% and NOx emissions by 80% compared to conventional boilers.

Simplify Your Installation

Fully electronic combustion controls use Flame-by-Wireâ„¢ technology. This installer friendly system is simpler to learn and operate, significantly reducing commissioning time and complexity.

Trusted Long-Life Durability

Firetube architecture is recognized for superior dependability and ease of installation. The ENDURA XE envelops tubes within a large volume of water, eliminating costly buffer tanks and primary-secondary piping.

300-Bosch-Industrial-steam-boilers-2-UNIVERSAL steam boiler U-ND-U-HD- main

Universal Steam Boiler U-ND/U-HD

This boiler combines the advantages of shell boiler technology with the efficiency of the flame tube/smoke tube system. It operates on the reverse flame principle, making it particularly suitable for smaller manufacturing businesses, processing industries, and service sectors.

Weishaupt 4LN-version gas burners

Weishaupt 4LN-Version Gas Burners

Weishaupt 4LN-version gas burners are an innovative further development of patented multiflam® technology combined with flue gas recirculation.

Advanced Multiflam® Burner Design

At the heart of this further development of larger multiflam® burners lies a swirl body in the secondary air area and a longer flame on the primary diffuser.
In combination with flue gas recirculation, the swirl body generates an intensive mixing of the fuel, air, and recirculated flue gas. The primary flame, which is adapted for high flue gas recirculation rates, ensures the flame remains stable at
all stages of operation.
