Product Information
2VITOROND 200, VD2A
VITOROND 200
The Vitorond 2 is a triple-pass sectional
cast iron oil-/gas-fired boiler for commercial
heating applications.
Its Eutectoplex heat exchanger provides high
operational reliability and a long service life,
while the triple-pass design ensures
efficient, low-emission combustion.
The VD2A Series features Therm-Control
integrated low-temperature protection logic
and a redesigned return water distribution
system for a simplified design and system
integration.
he benefits at a glance:
HEfficient and reliable operation. Modulated
boiler water temperatures help conserve
energy by closely matching system output
to actual demand. Viessmann system
controls ensure consistent, maximum
system efficiency.
Combustion efficiency up to:
- oil 87.7%.
....................................................
- gas 84.8%...................................................
Thermal efficiency up to:
- oil 87.9%.....................................................
- gas 85.2%...................................................
HSimplified design and system integration
with Therm-Control integrated
low-temperature protection logic,
eliminating the need for a low-temperature
protection package or shunt pump.
No minimum boiler return water
temperature when used with Viessmann
Vitotronic controls.
HSimplified water connection. Wide water
galleries and a large water content provide
excellent natural circulation and a reliable
heat transfer. No minimum heating water
flow rate required.
HHigh operational reliability and a long service
life are achieved by the special Eutectoplex
gray cast iron heat exchanger. A uniform
heat transfer and controlled water flow,
together with inherent characteristics of the
cast iron sections, eliminate stress fractures,
counteract the formation of condensate and
extend the lifecycle of the boiler.
HLow environmental impact thanks to
low-emission combustion achieved by the
boiler’s triple-pass design.
HProblem-free transport into
difficult-to-access boiler rooms thanks to
sectional construction and low weight of
individual sections. The Fastfix system
facilitates a quick and easy installation.
HSimple, quick assembly of the individual
cast iron sections with new
tongue-and-groove system with silicone
sealant. The gasket seal is secured in
place by the double groove, and therefore
not subject to mechanical stresses.
HEasy cleaning access facilitated by a
hinged left- or right-swing combustion
chamber door providing easy access to all
three flue gas passageways from the front
of the boiler, reducing side clearance.
HEfficient and safe operation of the heating
system with Vitotronic digital boiler and
heating system controls. Tailored to suit
every requirement, these controls cover all
known control strategies and applications.
Standardized LON BUS enables complete
integration into building management
systems. Optional integration into the
Vitocontrol control panel.
HConsistent and reliable DHW production
with indirect-fired Vitocell 1 steel or
Vitocell 3 stainless steel tanks.
Tanks may be combined into multiple-tank
batteries for applications requiring larger
quantities of hot water.
HComprehensive standard equipment saves
valuable time in installation and sourcing
of product. The supply and return header
system is pre-built for left or right
connections and positions components
properly.
HBoilers, controls, domestic hot water
tanks, and heating system components
are design-matched to work together. All
components are compatible and are
therefore quickly and easily installed.
