Modernisation pays off: The average service life of boiler systems that are used for industrial purposes is between 20 and 40 years. Many measures which previously were not possible or financially justifiable pay off nowadays after a very short period of time. Five good reasons to modernise your energy generating system: — Reduce operating costs — Security of supply — Structural adjustments — Sustainability — Maintaining legal conformity
