Automation Industry (CMM Machine Rooms such as Laser/Printing Machines)

CMMs are devices used to measure the geometrical characteristics of a component. CMM rooms are utilized to tasks and actions such as manufacturing inspection and gauge calibration among others. The deployment is carried out at mission-critical applications and ecosystems such as Aerospace, Automotive, and light industrial applications.

Load Profile: These electro-mechanical devices contribute high density and dry heat loads.


1: CMM rooms need controlled constant temperature which doesn’t fluctuate or deviates often from the defined range (for example, 20° ± 1°C)

2:  Optimal air distribution with fixed air velocity.

3:  24 X 7 uptime availability.

4:  Dust-free environment and clean ambiance without any debris.

Prerequisite parameter: Temperature tolerance – ± 0.5°C to 1.0°C, RH – ± 3% RH to 5% RH, positive pressure, and air velocity – 3 FPM to 20 FPM.

We at AB3S Solutions have partnered with Vertiv Energy (Formerly Emerson Network Power) to provide Precision Air Conditioning Solutions for above needs. The product typically used in above Rooms is PDX machine.

1: Liebert PDX systems help maintain highly accurate and precise control on temperature and relative humidity.

2:  The digital scroll technology combined with a PID logic-based micro-controller helps maintain a narrow band of temperature tolerance.

3:  EC fan delivers optimal air volume as per the preset limits and required by air distribution.

4:  The Liebert solutions are capable of running 24*7 operations apart from maintaining a constant temperature-based ambient environment while the G4 filter comes as a regular item with the Liebert package, the optional F5 filter can also be chosen as per the site requirements.


The Liebert® PDX direct expansion cooling unit is equipped with the most advanced industry technology, guaranteeing precise cooling of data centres and server rooms.

It comes complete with R410A refrigerant which allows the unit to reach significant levels of efficiency. The Liebert PDX range also includes new generation Liebert EC Fans 2.0, thus ensuring top energy efficiency. The complete unit design has furthermore been optimized with enhanced heat exchangers, delivering high levels of overall efficiency and cooling capacity. In addition, Liebert PDX also includes unique Digital Scroll technology, making it the ideal, scalable cooling system able to expand with evolving business needs. The Digital Scroll modulating capability greatly contributes to the efficiency levels reached by Liebert PDX with a 50 kW unit (inclusive of Digital Scroll) consuming as little as a 10 kW unit, thus delivering advantageous energy savings.

Liebert PDX range is available from 15KW to 120 KW of Cooling Capacity.
