XL W WALL HUNG

One of the most powerful wall hung commercial boilers on the market. Extremely flexible, thanks to a wide range of accessories and different cascade system configurations: in-line, in-line duo, back-to-back and back-to-back duo.

Reliable and robust
Robust at heart thanks to the stainless steel heat-exchanger. Main advantage compared to aluminium is the boiler is four times more corrosion resistant.

With up to 2 heat exchangers ‘on board’, working indepently, XL W has an integrated back-up system. This results in a very high efficiency and a modulation rate of up to 1:10 from a single boiler.

EFFICIENT & LOW LIFETIME COSTS

HIGH RELIABILTY
SUPERB HEATING EFFICIENCIES
HIGHLY COST COMPETIVE
EXTREMELY LOW CO/NOx EMISSIONS

SERVICEABILITY & PERFORMANCE

The HMI is placed on top at a convenient height of 1.70m and all inner parts are accessible from the front.

The engineering excellence results in keeping the heat and noise inside thanks to the full insulation of expanded propyleen. For even better efficiency rates.

3-ZONE TECHNOLOGY

By combining the highest quality materials and improved
design, based on 30 years of heat exhanger experience, the ATAG XL F delivers with the new iCon XL heat exchanger
excellent efficiencies during the lifetime of the boiler, as well as low maintenance schedules.

Specially designed smooth tubes ensure direct heat transfer, plus a down-firing arrangement avoids pollution of the heat exchanger. The three combustion zones minimise formation of NOx and CO. Even, the NOx emissions undercut the EU limit by 60%.

INTELLIGENT INTEGRATED PUMP

Both ATAG XL W and XL F communicate with the
integrated pumps and receive feedback on its operation status. This modulating pump is constantly monitoring the flow rate and recognizes blockages, preventing damage, guaranteeing optimal working conditions and improving boiler efficiency.

EASY CONNECTION

Built-in as standard, a non-return valve allows easy connection of the flue system, without
loss of residual fan pressure.

CONFIGURATION POSSIBILITIES

CASCADE

XL W and XL F boilers are quick and simple to install with multiple configurations possible. This ensures they are perfect for a wide range of plant rooms, especially where space is at a premium.
With options for wall mounted and floor standing both free standing in-line and back-to-back arrangements, the boilers offer a variety of modular installations.

HIGH RELIABILITY

A beneft of the XL design is the downfring burner, which further prevents contamination, while acting as an insulator above the heat exchanger. The design of the heat exchanger, combined with the boilers’ all-round reliability, allows ATAG to provide a 7 year parts and labour warranty as standard. Plus, for added peace of mind, this can be extended to 10 years (subject to terms and conditions).

LIGHTWEIGHT MATERIALS

By utilising the latest lightweight materials, ATAG XL can be easily commissioned and transported on site.

Thanks to its stainless steel heat exchanger, there are no compromises on durability and robustness. In addition, its low water content design and advanced co mbustion technology facilitate rapid heat transfer and extremely high efficiencies

CONTROLL BOX

The XL allows easy integration with well-established building management systems (BMS), further optimising the overall system efficiency and is compatible with common protocols used in building automation such as Modbus and KNX.

HEAT AND NOISE INSIDE

A completely expanded polypropylene insulated body encases the boiler to keep heat loss to an absolute minimum for improved boiler efficiency. Besides this the high quality casing minimises noise emissions to industry leading standards.
