Steam boiler
VPK series
A compact steam boiler for small and medium duties
The same three-pass principle in a compact body — for plants needing up to 5,000 kg/h of steam. Low flue-gas resistance cuts the burner's electricity use.

Design
A compact steam boiler for small and medium duties
01
Three flue-gas passes
Furnace load below 1.3 MW/m³ — high efficiency and low emissions.
02
Small water volume
Fast start-up and drier steam at peak draws.
03
Corrugated furnace tube
Extra furnace strength and resistance to thermal stress.
04
Efficiency up to 91%
An economiser adds up to 5% more from flue-gas heat.
