Product Information

Vitocrossal 200
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.
