| | | steute - the \CX/perts As specialists for Ex switchgear steute offers an extensive program of explosion-proof certified protection switches, command devices, position switches, magnetic reed switches etc. to the manufacturers of machines and plants. Thus steute contributes, that in sensitive fields a high degree of safety for men, environment and plants is achieved. Ex switchgear from steute are used among others in the chemical and petro-chemical industry as well as in enamelling systems. But also where high fine dust concentrations can lead to explosions by deflagration - e. g. in mills, in wood processing, pharmacy and filling of powdery materials - the machine and plant manufacturers as well as the end-user use the know-how and the switchgear from steute. | | |
