AT-Series: Laser Shaft Alignment Tools Overview

Acoem is a renowned Laser Shaft Alignment Systems manufacturer, offering the AT-Series range of tools tailored to different applications and requirements. The lineup includes the AT-100, AT-200, AT-300, AT-400, and EXO, each designed to address specific alignment challenges across various machinery types. This article aims to highlight the benefits of the AT-Series of tools and assist in the selection of the appropriate solution.

AT-100: Entry-Level Efficiency

The Acoem AT-100 serves as an entry-level laser shaft alignment system suitable for a wide range of applications including direct-coupled, rotatable, and standard horizontal machinery. This tool is ideal for aligning equipment such as fire pumps and small blowers or small fans. The AT-100 offers a cost-effective solution for basic horizontal alignment tasks.

Ideal Machinery:

  • Fire Pumps
  • Blowers (Small)
  • Fans (Small)


AT-200: Enhanced Capability and Versatility

Stepping up in capabilities, the Acoem AT-200 has enhanced hardware with its bigger detector and higher resolution inclinometer. The tool offers advanced features to align horizontal and vertical machine setups effectively. With the ability to enter growth targets and compensate for thermal expansion or pipe strain, this model solution is suitable for larger machinery such as industrial pumps, blowers, and fans. It provides a more pleasant sufficient user experience with the larger AT display unit and FeetLock™ application to overcome bolt-bound situations.

Ideal Machinery:

  • Industrial Pumps
  • Blowers (Small or Large)
  • Fans (Small or Large)

AT-300: Precision and Adaptability

The Acoem AT-300 represents a further advancement in laser shaft alignment technology, featuring improved 3rd-generation digital sensors and inclinometer for enhanced accuracy. This tool can align a broad spectrum of machinery, including Spacer and Cardan shaft coupled configurations. 

Notable features of this tool include Hot Check™ which facilitates verification of thermal growth and a Machine Train* program which allows for the alignment of complex setups involving multiple components and couplings, such as a Motor-Gearbox-Generator setup. 

Additionally, it includes an alternative measurement mode known as Dual Multipoint which enables the recording of measurements at more than three locations. This adaptable mode is particularly beneficial for turbine alignments, facilitating the capture of multiple individual measurement points at any desired rotational position.

*Machine Train will be available late 2024.

Ideal Machinery:

  • Pumps, Fans, or Blowers
  • Machines with Spacer Shafts
  • Machines with Cardan Shafts
  • Machine Train Configurations
  • Turbines



AT-400: Flagship Performance for Alignment Experts

At the pinnacle of the AT-Series portfolio is the Acoem AT-400, which offers unparalleled capabilities tailored for alignment experts. Its innovative 2-Axis sensors with large detectors enable precise alignment of horizontal, vertical, and various coupled or uncoupled machines, even in rough alignment situations. 

The Dual Sweep measurement mode simplifies the measurement process by automatically capturing numerous data points with real-time adjustments during the live move monitoring of the movable machine. The OL2R* (“Offline to Running”) mode enables the precise measurement of thermal growth and other offline-to-run impacts with the utmost accuracy. These findings can be integrated into the shaft alignment measurement procedure, strategically aligning machines in cold conditions to achieve optimal alignment during operation.

Furthermore, the flatness add-on extends the AT-400’s utility beyond alignment, enabling the assessment of foundation and surface flatness. Basically, all types of machinery, including compressors, blowers, fans, turbines, pumps, gearboxes, agitators, cooling towers, and numerous others, can be aligned accurately and precisely with this top-of-the-line solution.

*OL2R will be available late 2024.

Ideal Machinery:

  • Pumps, Fans, or Blowers
  • Machines with Spacer Shafts
  • Machines with Cardan Shafts
  • Compressors
  • Turbines
  • Gearboxes
  • Agitators
  • Cooling Towers
  • Generators

EXO: Intrinsically Safe Alignment

The Fixturlaser EXO is Acoem’s Intrinsically Safe Laser Shaft Alignment Solution. The EX certified tablet (ATEX/IECEx Zone 2 Certification) and sensors (II 3D Ex ic op isIIC T4 Gc Certification) ensure both compliance and safety in hazardous environments. With the ability to align both horizontal and vertical machine setups, alignment can promise precision in those designated areas and hot work permits can be avoided.

The EXO’s proven dual laser system cuts through complexity, allowing you to tackle alignments on virtually any rotating equipment and coupling type. Forget tedious setups – multiple measurement methods, including the powerful Dual Multipoint measurement mode, make even intricate adjustments a breeze. From standard fans and vertical pumps to compressors, and beyond, the EXO empowers you to achieve perfect shaft collinearity with ease and user-friendly guidance.

Ideal Machinery:

  • Fans
  • Pumps
  • Machines with Spacer Shaft
  • Compressors
  • Generators
  • Engines



In conclusion, Acoem’s AT-Series of Laser Shaft Alignment Systems cater to various alignment requirements, from basic setups to complex industrial machinery. Choosing the suitable model depends on factors such as the type of machinery, alignment precision needed, and budget considerations. Whether it’s the entry-level efficiency of the AT-100 or the flagship performance of the AT-400, Acoem ensures that users can invest in the right equipment for their specific application needs. With all systems connected to the Internet and Acoem Cloud, users can easily store, archive, and analyze alignment data, ensuring optimal machinery performance over time.
