Product Information
The benefits at a glance:
H
Eutectoplex heat exchanger surface for high operational
reliability and a long service life.
The homogeneous structure of the Eutectoplex special
gray cast iron ensures uniform heat transfer, minimizing
stress fractures and counteracting the formation of
condensate.
Shape and geometry of the cast iron sections, excellent
water flow characteristics and uniform temperature
distribution further increase the level of operational
reliability.
H
Problem-free transport into difficult-to-access boiler
rooms due to sectional construction and low weight
of individual sections.
H
Efficient and environmentally friendly operation due
to modulated boiler water temperatures.

VITOROND 200
The modular sectional cast iron design of the Vitorond
200, VD2 allows for problem-free transport into difficult-
to-access boiler rooms and permits easy assembly.
The triple-pass design ensures clean, low-emission
combustion, while the Eutectoplex heat exchanger
surface guarantees economical energy consumption,
high operational reliability and a long service life.
H
Simple, quick assembly of the individual cast iron
sections is achieved with a double-groove seal fit
system for the flue gas passageways. The gasket seal
is secured in place by the double groove, and therefore
not subject to mechanical stresses.
H
Easy cleaning access facilitated by a hinged (left
or right) swing-open combustion chamber door,
allowing easy access to all three heat exchanger passes
from boiler front, reducing side clearance.
H
Economical and safe operation of the heating system
with Vitotronic or Dekamatik digital boiler and heating
system control.
Tailored to suit every requirement, these controls cover
all known control strategies and applications.
H
Economical and hygienic domestic hot water production
with indirect-fired Vitocell 100 steel or Vitocell 300
stainless steel tanks.
Tanks may be combined into multiple-tank batteries
for applications requiring larger quantities of hot water.
