CORE DUODouble vertical water heating boiler with redundancy Boilte Core Duo
Boilte Core Duo – double water heating boiler with redundancy
Boilte Core Duo is a double vertical water heating boiler that represents a comprehensive engineering solution, where two highly efficient fire-tube boilers of the Core series are combined into a single vertical energy module. Total thermal power – from 140 to 2000 kW. Heat carrier temperature – 60–115°C, operating pressure – up to 6 bar. Efficiency – up to 94%. Estimated service life – over 25 years.
Core Duo is the choice for industrial, energy, and infrastructure facilities where uninterrupted heat supply and space savings are critically important. Two independent boilers in one casing provide mutual redundancy: if one module fails or requires scheduled maintenance, the second continues to operate, maintaining the heat supply to the facility.
The vertical binary configuration significantly increases the specific power per unit of occupied area, which is critically important when designing cramped or expensive spaces. Space savings compared to two separate horizontal boilers reach 40–50%.

Frequently asked
What is the main advantage of Core Duo over two separate boilers?
Core Duo is a factory integration of two boilers into a single vertical module with a common piping system. This saves up to 50% of space compared to two horizontal boilers, reduces installation costs, and provides a turnkey solution.
How does redundancy work?
Two boilers operate independently. If one module fails or is under scheduled maintenance, the second continues to operate, maintaining the heating supply to the facility.
What fuel savings are achieved through cascade control?
The cascade control system dynamically distributes the load between the modules, keeping each boiler operating in the zone of maximum efficiency. Fuel savings reach 20–30% compared to operating a single large-capacity boiler at partial loads.
What warranty is provided?
Lifetime warranty on the heat exchanger and main load-bearing elements of each module when installation, operation, and water-chemical regime rules are followed.
