KÖBER Ltd Vaduri Branch - the producer of MOTAN wall hung gas boilers participated as exhibitor at the International fair Mostra Convegno EXPOCONFORT Milano 2010. It is KOBER's second consecutive participation at MCE Expoconfort. Within the exhibition, we exhibit all the MOTAN range of products MOTAN: MOTAN MKDens 25, MOTAN MKDens 36, MOTAN MAXOPTIMUS, MOTAN OPTIMUS, MOTAN START, MOTAN PLUS, MOTAN KPLUS as well as Storage Tank BA120LPV.
Please find a selection of images from MOSTRA CONVEGNO EXPOCONFORT here.
MOTAN MKDens25 and MKDens 36 condensing wall hung gas boilers constituted the novelty for MOTAN stand. These two models was launched in August 2009 and have "CE" type examination certificate The MKDens MOTAN type have "CE" type examination certificate issued by Gemanischer Lloyd Industrial Services (Germany) following the tests carried out in 2 laboratories from UK. Following the tests results, both models reached A Energy Efficiency Band (natural gas) (Sedbuk A), with 106,7% net efficiency at 30% part-load (natural gas) at MKDens 25 model and 106,5% net efficiency at 30% part-load (natural gas) at MKDens 36 model.
Commissioning and service is free throughout the warranty period that is of 3 years for all models of boilers.
