The powerful Vitocrossal 300 is designed for flexible use in the medium output range. With an output range of 87 to 1400 kW, it is an efficient solution for heating in apartment blocks, as well as in public and commercial buildings.
The Vitocrossal 300 CR3B is a gas condensing boiler delivering an output of 787 to 1400 kW. As a single boiler system, it is Viessmann's most powerful heating centre.This makes it just as suitable for residential complexes as for local heating networks, larger public and commercial buildings and industrial plants.
The Vitocrossal 300 is supplied with a pressure-jet gas burner from either ELCO or Weishaupt.
The design of the heat exchanger in the Vitocrossal 300 enables high output levels, yet retaining modest dimensions and a low weight.
To facilitate handling, the condensing boiler can be delivered in two sections.
The Vitotronic control system with a large colour touch display allows fast commissioning by means of an assistance function as well as simple operation. Via the integrated LAN interface, the boiler can be directly connected to the Internet for remote monitoring. The Vitosoft 300 service tool communicates directly via WLAN. Energy consumption can be easily viewed via the control energy cockpit.
The burner delivers an output of up to 314 kW and adjusts its heat generation from 30 to 100 percent as required, to save energy. Further features include particularly quiet, economical and environmentally responsible operation.
Alternatively, the boiler is also available factory fitted with ELCO or Weishaupt pressure-jet gas burners.
