VIESSMANN VITODENS 200-W CASCADE Prefabricated Multiple Boiler System

GAS CONDENSING TECHNOLOGY

In a cascade system, the Vitodens 200 becomes a powerful commercial heating system capable of satisfying even the largest commercial heating loads.

Vitodens 200-W Cascade Systems

1. Vitodens 200-W, B2HA gas condensing boiler
2. Low-Loss Header
3. Vitotronic 300-K, MW2C Cascade Control
4. Circulators, check valves
5. Distribution manifold

Performance and efficiency
The Vitodens 200 is one of the most efficient and powerful wall-mounted condensing boilers on the market. By itself, it is ideally suited for residential applications. But in a cascade system, the Vitodens 200 becomes a powerful commercial heating system capable of satisfying even the largest com- mercial heating loads.
Equipped with proven Viessmann technology, including the MatriX cylinder burner and Inox-Radial heat exchanger, the Vitodens 200 delivers outstanding performance. Plus, with the Lambda Pro® combustion management system, each Vi- todens 200 in your cascade system will operate at maximum efficiency, reducing heating costs without
compromising comfort.

Strength in numbers
As many as eight Vitodens 200 gas-fired condensing boilers can be combined in a single prefabricated cascade system, with inputs up to 4240 MBH. A cascade system fires boilers as required to meet fluctuating heating demands; it maintains maximum efficiency at all times by precisely
matching the load. A cascade system can also prevent interruption of heating plant operation, with multiple boilers available as back-up.

Portable and convenient
The Vitodens 200 cascade system is your most flexible installation option for problematic retrofits and small spaces. The prefabricated distribution manifold is floor-mounted and is available in a variety of configurations: single-line, corner or back-to-back for ultimate installation flexibility.
With all components individually packaged, the cascade system is ideal for small or difficult-to-access boiler rooms or facilities with narrow halls or stairwells.

Easy installation
The Low-Loss Header increases operational efficiency of a cascade system by ensuring low return temperatures and acting as a hydraulic break – decoupling boilers and system circuits. Right or left-mount, the Low-Loss Header allows the cascade to be installed in a variety of configurations. The system’s prefabricated distribution manifold allows boilers to be easily field assembled, wired and piped prior to system installation.

The Vitodens 200 is ENERGY STAR® qualified. By choosing the Vitodens 200, you are helping to promote cleaner air and a healthier environ-ment.

Controlling your cascade
Get the best performance from your multiple-boiler installations with the Vitotronic 300-K, MW2C Cascade Control. This advanced digital boiler and system control with outdoor reset function ensures reliable and efficient performance of a cascade system with up to eight boilers (with Vitotronic 200, HO1B controls).
The Vitotronic 300-K control will modulate, stage and rotate boilers, regulate boiler water and common supply temperature, and with optional extension module, can control up to two heating circuits with mixing valves. Plus, set- up is fast and easy with its plug-and-play function for automatic recognition and adaptation of sensors and system accessories. The Vitotronic 300-K control also allows seamless integration into Building Management Systems (BMS) without additional gateway (limited access). Use of commercially available LON equipment for further inputs and outputs is optional (coupling via standard LON tools up to three heating circuits).
