Alignment system for hazardous environments

01 September 2007

John Crane has launched Lase-A-Lign Ex, a shaft alignment system specifically designed for use in hazardous and potentially explosive environments. This makes it especially suited to the petrochemical, oil, gas and pharmaceutical industries where it can be used on various types of rotating equipment such as motors, pumps, turbines, compressors, gearboxes and blowers.

The system minimises the risks involved when undertaking on-site operations in extreme environments, and its durable stainless steel and anodised aluminium construction is impact, corrosion, water, dust and leak resistant. Environmentally rated to IP66 and IP67, Lase-A-Lign Ex also complies with the latest ATEX standards II 2 G EX classification: EEx ib IIC T4.

In addition to its horizontal and vertical shaft alignment capabilities, the instrument also provides the user with a range of additional programs to measure straightness/twist, vertical and flange-mounted machines, alignments of Cardan-shaft-coupled/centre offset machines and angular error between two rotating shafts. This greatly increases flexibility and makes the unit ideal for both installation and maintenance work.

“Lase-A-Lign Ex has been approved by the international testing and certification body Nemko AS, which is further independent proof of its value,” says John Crane product manager Peter Simpson. “It has been thoroughly tested in the most demanding environments to ensure that it meets the very highest standards and that’s why we are able to offer a four-year warranty.”
