JUMAG electric steam boiler EDI

The EDI series steam boilers are electrically operated. They provide steam outputs from 20 kW to 360 kW. This capacity can be multiplied with multiple units

JUMAG electric steam boiler EDI Fail-safe and sustainable - up to 480 kg steam/h


High steam quality

  • Constructed in high-quality stainless steel for production of pure steam  
  • Large water surface for dry steam  
  • Integrated drop separator keeps the steam dry even at low pressure  
  • Optionally available with Feed water pre-heating for partial degassing  
  • Immediate load adjustment by electronic power control  

Robust and low-maintenance

  • Use of high-temperature resistant heating rods  
  • Modulating control of the heating elements, thus minimum load 
  • Thyristors extend the service life of the electrical parts 
  • All components made of stainless materials (optional stainless steel)  
  • No power consumption peaks due to symmetrical network load

JUMAG electric steam boilers in detail

How it works

Why do JUMAG steam boilers require minimal maintenance and boast maximum energy efficiency? This is due to the fact that they work differently from the classic electric steam boilers.

Depending on the water level in the pressure vessel, the feed water is refilled into the pressure vessel through the integrated boiler pump.

Low surface load on the heating rods due to larger diameter and longer heating rods. Approx. 10 W/cm² compared with up to 26 W/cm² for competitors

Wear-free control of the heating rods: Thyristors switch during phase change without voltage, unlike contactors, which switch and wear out with voltage. Thanks to the thyristors, the power grid is protected because current peaks are avoided during switching

All materials are made from high-quality stainless steels. Optionally completely made of V4A (all components without exception!)
