JUMAG Multiple UnitSteam Systems

If a single steam boiler cannot meet the maximum steam demand, or if a fail-safe steam supply through redundancy is desired, a multiple unit steam system is recommended. For this purpose, several steam boilers are set up in parallel. They use a common water supply and a common blow down vessel.

Combine oil or gas with electric steam generation: JUMAG multiple unit steam systems are also available as hybrid solutions. This will give you more flexibility for your future energy mix.
