Products belonging to TER ATEX series are suitable for hazardous, potentially explosive areas. Hazardous areas are places where, under certain conditions, explosive atmosphere may form. An explosive atmosphere is a mixture of air and gases, vapours, fumes or combustible dust, whose combustion spreads rapidly (explosion) after ignition at atmospheric pressure. Users are responsible for carrying out a classification of hazardous areas, as set out in European Directive 1999/92/EC. International standards IEC 61241-10 provide criteria for classification of hazardous areas depending on their chemical nature, physical characteristics and quantity of substances used, as well as on the frequency and length of time when an explosive mixture may occur.
TER’s aim is to simplify the control of the machines equipped with its devices, designing reliable, ergonomic and intuitive safety products, capable of predicting the demands of the market and becoming the industry benchmark.
At the basis of this company mission is the will to establish a connection between market and company, by giving an increasingly central role to the sales department, seen as a continuous relationship between TER and its customers.
