The ambient temp詩rature range can be from -60°C to +70 °C and the degree of protection certified is up to IP68 (2010) 0 The release of a new component certificate relevant to individual heating lments for ambient heating and Exe protection mode (2010) When the ATEX Directive 94/9/EC became applicable, the design, production control and documentation pr驩paration working mthodologies relevant to thse type of products were changed. Thanks to the already existing company organisation. this change dld not pr騩sent signrfcant difficulties. In fact Masterwatt was the first Italian company to obtam, in October 2001 ( the production quality certification for to the manufacturing of explosion proof eleethe heaters compilant to ATEX directive. Since 2001 the range of explosion proof heaters has been widened, obtaining the certification of diffrent manufacturing solutions and more severe operational conditions, Today we can provide the following products that are compliant to the ATEX directive: 0 Flanged heaters and electrical heat exchangers M Heating plates and aluminium or bronze cast heaters e 0 Plug-mounted heaters | 0 Air Duct heaters and anticondensation heaters 0 Single smooth or finned anticondensation heaters % www.masterwatt.it Explosion Proof Heaters oage 1/14
