We have used the ROTALIGN ULTRA 5 times
in the past 2 weeks and I want you to know
how impressed I am with this machine.
It has saved both time and money. Thanks!
Jon Walsh, NIPSCO

We did our first alignment using the
ROTALIGN ULTRA, it worked great!
—Bill Heath, Naval Air Depot

We purchased three OPTALIGN PLUS laser alignment units at the start of a plant reliability program. These units were used in an effort to take our rotational equipment installations to a precision state. We grew in reliability and purchased two ROTALIGN ULTRA units. The LUDECA equipment is very durable and easily used in our chemical plant maintenance department. LUDECA has always been very helpful in obtaining upgrades and efficient in any repairs required to the precise laser alignment equipment. The equipment is very user friendly and has allowed maintenance to precisely install all rotational equipment. We have found the LUDECA equipment to be a standard tool in our maintenance department and compliments our Reliability Program efforts.

Our shaft alignment systems feature the patented automatic CONTINUOUS SWEEP measurement mode which evaluates hundreds of readings during shaft rotation. This compares to
shooting a movie vs. only taking flash pictures at certain intervals. The end result is less shimming
and horizontal moves because you are measuring much more accurately.
