Steam boilers, engineering and Hands-on Green Conversion

Mainly by using Jumag steam boilers and TLV steam components we supply smaller and mid-sized energy efficient industrial steam systems in the Nordic countries. It can be a ZERO emission solution, CO2 neutral or using conventional fuels.

By higher energy demand we use Hagelschuer modular boiler systems. It can be a skid mounted system or a mobile unit. The boiler body can be from various manufactures but the digital controls and system lay-out and design is Hagelschuer’s own exclusive design.
