Product Information
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 r eliability and a long service
life.
The benefits at a glance:
H Efficient and environmentally friendly
operation due to modulated boiler water
temperatures.
Combustion efficiency:
- oil 88%.
.......................................................
- gas 85%......................................................
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 Low-emission combustion through
triple-pass design.
H Problem-free transport into
difficult-to-access boiler rooms due to
sectional construction and low we ight of
individual sections.
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 (le ft or right) swing-open
combustion chamber door, allowing easy
access to all three heat exchanger passes
from boile r front, reducing side cleara nce.
H Efficient and safe ope ration of the heating
system with Vitotronic or Dekamatik
digital boiler and heating system control.
Tailored to s uit every requirement, these
controls cover all know n 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 a pplications requiring larger
quantities of hot water.
