Vitoplex 300 - triplex pipes for large heating surface

Benefit from these advantages:

• Low temperature oil/gas boiler, rated from 90 to 2000 kW
• No low water indicator required up to 300 kW
• Sizes from 620 kW with walk-on boiler cover, for easier installation and maintenance
• Compact design for easy handling and low build height, important for modernisation projects
• Environmentally responsible operation thanks to long burner runtimes and fewer cycle intervals

Three-pass boiler with integral start-up control

The Vitoplex 300 steel boiler is available in two versions from 90 to 2000 kW. It is the universal heating system for new build and modernisation.

The multi layered convection heating surfaces consist of telescopically arranged triplex pipes pressed into each other. The internal pipe surrounded by folded linear fins creates a heating surface 2.5 times greater than that of a smooth pipe.

The integral Therm-Control start-up system makes a separate return temperature raising facility unnecessary.

Convenient and highly capable control units

Economical operation of the heating system is ensured by the digital Vitotronic control unit.

The Vitotronic 300-K is a particularly capable version for multi boiler systems comprising up to four individual boilers with modulating boiler water temperature.

The Vitotronic 200-H regulates up to 96 additional heating circuits.

Integration into building management systems is possible. The TeleControl system with the Vitocom and Vitodata is available for remote monitoring via internet.

Multi-layer convection heating surfaces from triplex pipes

The multi-shell convection heating surfaces of the Vitoplex 300 consist of interlocking steel tubes that are pressed together to conduct heat. With its folded longitudinal ribs, the inner tube forms a heating surface 2.5 times larger than smooth tubes.

The heat transfer is metered in such a way, in particular by varying the spacing of the pressed sections, that the rear section of the triplex tubes, through which combustion gases that are no longer so hot flow, dissipates less heat to the boiler water. In this way, the surface temperature remains above the dew point temperature, condensation is counteracted, and corrosion damage is avoided.
