The ECOS has been able to prove a total of 9 efficiency world records in TÜV SÜD boiler tests. For this purpose, TÜV SÜD carried out boiler tests and int. market research reports. In the field of condensing technology, which we offer as an option for the ECOS, peak values of 109.5% to 110.4% were achieved in condensing nominal load operation with wood chips, via TÜV SÜD. In the conventional range, the ECOS, TÜV SÜD tested, achieves top values of 96.4% to 98%.
