SLIMCompact two-pass water heating boiler Boilte Slim
Boilte Slim – compact water heating boiler for confined conditions
Boilte Slim is a two-pass compact water heating boiler designed for efficient use of space without compromising performance. Slim is the answer to the typical modernization problem: when the existing boiler room has limited dimensions, and replacing equipment requires fitting new power into old openings and spaces.

Construction
and materials
Two-pass smoke tube design with an extensive heating surface:
- ›Body made of boiler steel P265GH (EN 10028) (increased strength, impact toughness, corrosion resistance)
- ›Each critical weld seam undergoes validation using radiographic and ultrasonic testing methods with the issuance of a report
- ›Hydraulic tests – at a pressure 1.5 times higher than the operating pressure
- ›Manufacturing tolerances and control are 30% stricter than industry standards.
Fuel flexibility
Slim operates on natural gas, liquefied gas, diesel fuel, and fuel oil. The design allows for instant reconfiguration from one type of fuel to another. The ability to switch between gas and liquid fuel depending on price conditions provides financial protection for your business.

The Slim boilers come with a lifetime manufacturer's warranty on the heat exchanger and main load-bearing elements, provided that installation, operation, and water-chemical regime rules are followed.
Each boiler is accompanied by a complete set of technical documentation: passport, installation and operation manual, non-destructive testing reports, hydraulic testing reports, compliance certificates.
Serial model
parameters
For non-standard requirements, custom builds to the customer's drawings are available.

Frequently asked
How much more compact is Slim compared to standard boilers?
Slim can deliver power up to 2500 kW in an exceptionally narrow body. The space savings compared to standard configuration boilers reach 40% at the same thermal power.
Is it possible to install several Slim boilers in a cascade?
Yes, multiple units can be arranged in a row to create a high-capacity cascade system. The compact width of the boiler allows for more thermal power to fit in the same boiler room area.
What is the actual efficiency of the boiler on diesel fuel?
On diesel fuel, the efficiency of the Slim boiler decreases by 1–2% compared to gas and is 91–93% depending on the burner settings and operating mode.
What warranty is provided?
Lifetime warranty on the heat exchanger and main load-bearing elements provided that installation, operation, and water-chemical regime rules are followed.
