Vitocrossal 300 Gas Condensing Boiler Type CR3B
Vitocrossal 300 Gas Condensing Boiler Type CR3B
The Vitocrossal 300, type CR3B, is the top model among floor-standing gas condensing boilers with a capacity of 787 to 1400 kW.
As a complete boiler system, it is the most powerful condensing boiler in the extensive range offered by AHI-Carrier. This makes it equally suitable for residential complexes, local heating networks, large public and commercial buildings and industrial plants.
Advanced condensing technology
The design of the Inox-Crossal heat exchanger allows the Vitocrossal 300 to produce higher power up to 1400 kW, while maintaining a modest size and low weight. In addition, the separate design of the heat exchanger module and the combustion chamber module makes it easy to maneuver.
Highly efficient heat transfer and high condensation rates achieve standard seasonal efficiencies [DIN] of up to 98% (Hs) [gross cv]. This high standard seasonal efficiency is the result of the principle of counter-flow between hot gas and boiler water, as well as the intense turbulization of hot gases as it passes through the heat exchanger.
The second return connector of the Vitocrossal 300 provides a hydraulic connection, which is very advantageous for the use of condensing technology.
The Vitocrossal 300 gas condensing boilers are supplied with factory-installed ELCO or Weishaupt pressurized gas burners.
User-friendly and high-performance Vitotronic control unit
The user-friendly Vitotronic control unit with a large colour touch screen enables fast commissioning via the assistant function. The boiler can be connected directly to the internet for remote monitoring via the built-in LAN interface. The Vitosoft 300 service tool communicates directly via WiFi. The energy consumption can be clearly seen in the power cabin of the control unit.
