WHAT IF THE UPGRADE COULD FIT THE PLANT YOU ALREADY HAVE?
For many brownfield plants, the opportunity to improve energy efficiency is clear. The harder question is how to introduce speed control within the space, infrastructure and operating requirements already in place.
Depending on the site, a conventional medium-voltage motor and drive setup may require additional electrical-room space, cooling, transformer infrastructure and long motor cable runs.
WHAT IF YOU COULD…
…upgrade without adding a separate electrical room?
<p>MV Titanium™ brings speed control next to the process, removing the need for a separate electrical room or e-house and additional cooling for it.</p>…reuse more of what is already there?
<p>Existing MV supply cables can be reused and the standard motor foundation can remain in place, reducing the amount of infrastructure that needs to change.</p>…avoid adding another transformer?
<p>MV Titanium™ can connect directly to the medium-voltage distribution network, removing the need for an additional transformer.</p>…bring more of the work into the factory?
<p>The complete package is factory pre-tested and parametrized, helping simplify commissioning and reduce on-site integration.</p>…use energy in line with actual process demand?
<p>Built-in speed control allows motor output to follow changing process requirements more closely, reducing unnecessary energy use.</p>…have one partner behind the complete solution?
<p>From the integrated motor and speed control to lifecycle services, maintenance and support, ABB provides one point of accountability throughout the solution lifecycle.</p>STORA ENSO: MAKING SPEED CONTROL FIT AN EXISTING PLANT
Stora Enso is a leading provider of renewable products in packaging, biomaterials, and wooden construction. At Varkaus Mill, in Finland, there was no space in the existing electrical room for another drive. See how MV Titanium™ helped bring speed control to the process, with the whole project completed in three weeks and calculated potential energy savings of around 47%.
WHAT’S IN IT FOR YOU?
<p>A more direct route means something different depending on your role.</p>
Improve efficiency without turning the upgrade into a major site project.
Reduce energy use while keeping uptime, reliability and installation disruption firmly in view.
What matters to you:
Lower energy costs. Less disruption. Practical installation. Reliable operation.
Less disruption on site
- Installed in the process environment, next to the pump, fan or compressor
- Existing MV supply cables and standard motor foundation can be reused
- Integrated cooling, so no additional electrical-room cooling is required
- Factory pre-tested and parametrized, so less work happens on site
Proof point (Stora Enso, Varkaus Mill, Finland)
A typical conventional variable-speed installation can take 6–9 months. At Varkaus Mill, where there was no room in the electrical room for another drive, the whole MV Titanium™ process was completed in three weeks.
Lower energy, reliable operation
- In a centrifugal pump, reducing flow by 20% through speed control can cut energy use by 49%
- Built-in connectivity supports condition monitoring and predictive maintenance
- 24/7 remote failure analysis and repair support
Make the upgrade easier to validate and implement.
An integrated, factory-tested solution designed to work with existing brownfield infrastructure can reduce interfaces, on-site integration and commissioning complexity.
What matters to you:
Infrastructure fit. Technical reliability. Maintainability. Straightforward commissioning.
Infrastructure fit
- Direct connection to the MV distribution network, without an additional transformer
- No space needed in the electrical room or e-house
- No long new motor cable runs, because the existing MV supply cables can be reused
Control settings and pre-commissioning are completed during factory testing, before the unit arrives on site.
- The standard motor foundation can be reused, and the unit is designed as a drop-in replacement for existing DOL motors
Maintainability
Support covers spare parts and maintenance programs, ABB's global service network, and built-in connectivity for data insights.
Build a stronger case around the whole project, not only the motor.
Reduced infrastructure requirements, lower energy use and a simpler implementation path can strengthen the long-term value of the investment.
What matters to you:
CAPEX and OPEX. Payback. TCO. CO₂ contribution. Long-term business value.
Payback and OPEX
A typical payback time is around 1–3 years. Lower energy use reduces OPEX over the operating life of the motor.
CAPEX: what you may not need to build
A conventional MV variable-speed installation can involve the following, and MV Titanium™ is designed to avoid or reuse much of it:
- An e-house (3–6 months for permits and construction)
- HVAC and fire protection
- A transformer and VSD cabinet
- Long motor cable runs
Savings potential (up to, depending on the existing control method)
- Pumps: 54% vs. throttling, 42% vs. on/off control, 17% vs. hydraulic control
- Fans: 63% vs. no flow control, 55% vs. outlet damper, 45% vs. inlet box damper, 43% vs. cycling, 33% vs. inlet vanes, 22% vs. slip coupling
Results at Stora Enso Varkaus Mill
~47% calculated energy savings, ~2,500 MWh/year and ~65 t CO₂/year. The CO₂ impact depends on the local energy mix.
Lifecycle
One ABB partner and single point of accountability, plus a Take-Back and Recycling Program for the replaced motor.
WHAT IF ONE UPGRADE COULD DO MORE WITH LESS?
<p>Explore the potential energy and CO₂ savings of speed control in pump and fan applications and see how one integrated package can simplify the upgrade from installation to lifecycle support.</p>
In many pump applications, flow is controlled mechanically while the motor continues to run at full speed. With speed control, motor output can follow actual process demand more closely, reducing unnecessary energy use.
Calculated energy and CO₂ savings can reach:
- Up to 54% vs throttling
- Up to 42% vs on/off control
- Up to 17% vs hydraulic control
For a centrifugal pump, reducing flow by 20% through speed control can reduce energy use by 49%, with associated CO₂ savings.
*Calculated values. Actual savings depend on the application, duty profile and existing control method.
Fan demand can vary significantly over time, while mechanical control methods may keep the motor running harder than the process requires.
Speed control allows airflow to follow demand more closely, with calculated energy and CO₂ savings of:
- Up to 55% vs outlet damper
- Up to 45% vs inlet box damper
- Up to 43% vs cycling / on-off control
- Up to 33% vs inlet vanes
- Up to 22% vs slip coupling
*Calculated values. Actual savings depend on the application, duty profile and existing control method.
MV Titanium™ brings the medium-voltage motor and built-in speed control together in one integrated package.
The solution is designed, factory tested and delivered by ABB, helping reduce the amount of additional infrastructure and on-site integration required around the upgrade.
Existing MV supply cables can be reused; no additional transformer is required and there is no need for a separate electrical room or additional cooling for it.
ABB can also support the solution throughout its lifecycle, from commissioning and maintenance to remote support and spare parts.
One integrated solution. One point of accountability.
