ROSTA Motorbases ATEX Applications for hazardous areas according to ATEX 94/9/EC Directive

ROSTA Motorbases ATEX The ROSTA Motorbase ATEX is offering with its mechanical pretensioning device the ideal calibration of the relevant belt tension, based on the test force recommendations of the belt suppliers. Motorbase ATEX is a specific ROSTA product developed to tension belts. It is a self tensioning unit where no additional check is required after first installation and has a long maintenance-free period for several years. The Motorbase MB ATEX is equipment to be used in environment with explosive gas of IIC group, temperature class T5, or combustible dust max. surface temperature...

Customer benefits of the ROSTA Motorbases Short-term slippage by the start-up of large inertias, avoiding excessive tension on belt-carcass Fast belt changing, no need of complex readjustment of the pulleys ROSTA Motorbases ATEX  4 Fully maintenance-free tensioning system, no need of periodical compensation of belt elongation

s ATEX in friction belt drives Prevents from slack accruement, avoids heat generating slippage of the belts and averts from premature belt failure Ideal belt tension, constant transmission of nominal torque, less energy consumption, can lead to threefold belt lifetime MB 70 Noiseless power transmission, all time ideally tightened belt sets ROSTA Motorbases ATEX  5
