  • mechanical speed variator max. 50 000 Nm, 0 - 1 200 rpm, ATEX 1 & 2 | MR series Planetroll GmbH & Co. KG
The plaromaster® MR are the world's leading variable-speed gearboxes in the explosion-proof area according to ATEX 95. They use the principle of rolling balls and are infinitely adjustable from and to zero speed, even with the highest starting or breakaway torques. They can be operated remotely by means of a hand wheel, or electrically. Due to the characteristics of the system, they cannot slip through - complex and costly ATEX external monitoring is not necessary.
