Vitocrossal 200
Product Information
Benefits at a glance:
Inox-Crossal heat exchanger surface made of high-
grade SA 240-316 Ti stainless steel for high
operational reliability and long service life.
- Easy dispersal of condensate through vertical gas
flues; therefore no concentration of condensate.
- Increased self-cleaning effect through smooth
stainless steel surfaces.
Highly efficient heat transfer and high condensation
rate through
- heat exchanger surfaces which intensely turbulate
the flue gas flow
- boiler water and hot gases flowing in counterflow.
Efficiency up to 98% through intensive condensation.
The flue gas temperature is only approximately 9 - 27° F
(5 - 15° C) above boiler return temperature (see chart
below).
Clean combustion - through perfect match of burner
and boiler, low combustion chamber loading and
straight-through combustion chamber.
Easy handling in boiler rooms through particularly low
build height and weight.
Easy installation and elimination of wiring mistakes
with Viessmann prewired plug-in system.
Heating boiler, heating system control, domestic
hot water storage tank and all other Viessmann
system technology components are coordinated to
one another.
All components are design-matched for quick
installation.
Pre-mix cylinder burner for environmentally-friendly
operation with a modulation range from 20 to 100%.
All hydronic connections can be fitted from above.
Economical and safe heating system operation
through Vitotronic digital control system with
communication capability. Tailored to every need,
covering all known control strategies and
applications.
Standard LON BUS for complete integration into
building management systems.
Particularly quiet operation.
High altitude operation up to 10,000 ft. (3000 m)
with a simple electronic adjustment.
