DG line – unmatched in energy efficiency
With its innovative design and use of high quality components, the Jumag DG stands out in a class of its own. It has a very high energy efficiency with up to 97% combustion efficiency and the possibility of condensing heating technology resulting in more than 100% efficiency with the use of a second economizer.
Ultra quick start-up procedure of only 8 minutes from standstill to fully operational. The Jumag DG is very easy to operate with its menu-driven full-text touchscreen with multiple language options. The start / stop procedure is simple by remote control, timer or manual. It comes with a full range of high quality accessories also supplied by Jumag.
It comes in sizes from 160kg/h to 560kg/h (5 different output-sizes). Furthermore, the diversity is enormous as the Jumag DG can be delivered as a multi-steam boiler unit with up to 8 boilers, as a ready to use compact steam-boiler unit built on a steel frame and even as a mobile unit in a custom build container with up to 4 or 5 boilers.
How it Works:
In a Jumag DG there is no heating-coil or piston pump. Controlled by the water level measured inside the evaporation chamber, the centrifugal pump refills the feed water vessel via the blow-down vessel and/or the economizer. The burner is controlled by steam pressure. A multiple-pass pipe transfers the burnt-gas heat through the evaporation system and to the water inside. Additionally, the economizer transfers residual heat from the exhaust air to the feed water stream. The special inner structure of the evaporation system provides the best dry steam results.
