Intrinsically safe and approved for use in potentially explosive environments.

The tool is attached in a few seconds, and you can easily see the laser line projected on the targets. When the line lies in the slots of the targets, the machine is in the right position. The result is a fast, precise alignment.

Transmissions with two or more belts, or wide belts, are highly affected by misalignment, causing large differences in belt tensions and also increased wear and tear on edges. When aligning with the Easy-Laser® BTA you reduce the wear on sheaves/pulleys, belts, bearings and seals as well as reducing vibration. Increased efficiency also means large energy cost savings.

Intrinsically safe products are used in a number of industries: Petrochemical, Oil/Gas, Refineries, Pharmaceutical, Paper mills, Bulk materials such as grain, fertilizer, sugar and salt mills, diverse Chemical industries such as the manufacture of dyes and bleaches.

Easy-Laser® D130 BTA Ex is approved in accordance with the latest ATEX directive and classified in accordance to IECEx regulations.
