Vitobloc 200

Combined heat and power plant for natural gas operation

  • Electrical power: 435 kW
  • Thermal power: 281 + 32 kW
  • Low emissions due to SCR catalytic converter
  • High electrical efficiency of 39.6%

Vitobloc 200

The Vitobloc 200 Type EM‑430/580 (SCR variant) is a high‑performance CHP unit designed for industrial facilities, large commercial buildings, and district energy systems with demanding requirements for efficiency and emissions control.
By simultaneously generating electricity and usable heat, the system achieves high overall efficiency and significant primary energy savings. The integration of SCR exhaust gas aftertreatment makes this variant particularly suitable for projects subject to strict emission regulations.

Why is SCR technology important for CHP units of this size?

SCR significantly reduces NOₓ emissions, making the system suitable for urban areas and sites with strict environmental limits.

What type of heat demand makes this CHP unit most efficient?

Facilities with continuous, high heat demand benefit most, as long operating hours maximise efficiency and economic return.

How does high electrical efficiency affect project economics?

Higher electrical efficiency increases on‑site electricity yield, leading to faster payback periods and improved return on investment.

What role does spare parts availability play in lifecycle costs?

Good spare parts availability ensures short repair times and predictable maintenance costs over the system’s lifetime.
