Unlock efficiency potential with industrial retrofitting services and smart manufacturing solutions.
Retrofitting services are developing at a full speed in the manufacturing industry. As the competition in the sector is razor-thin, every way to save operational spendings is pretty valuable, so turning to implement it in a clever fashion.
The representatives of manufacturing companies should put a tremendous effort into improving their production lines in order to optimize their production and reduce costs.
Any downtime brings heavy losses to the factories, so manufacturers consider the large volumes of components, their interoperability and plenty of factors in between.
In this blog post, we’ve decided to have a closer look at retrofitting in smart manufacturing. We will try to figure out how beneficial it could be for the industry in whole, what barriers it faces while being implemented.
As a software development company, we will explore the connections of retrofitting with the domains we are keen on the Industrial Internet of Things, machine learning and predictive maintenance.
We would also have a look at how deep retrofitting is applicable for saving energy in the buildings.
Retrofitting and Smart Factories: Benefits (Examples Inside)
As we’ve already mentioned, smart manufacturing aka ‘Industry 4.0’ is tightly connected with the concepts of predictive maintenance. To be precise, solutions developed in these domains help the ideas of retrofitting in their existence.
Purchasing new machines in line with the new smart technologies is way too expensive and is not practical especially for small and medium manufacturing companies. This is where retrofitting is a perfect fit.
Smart factory retrofit solutions enable an old machine or system to get access to new technologies. The details can be installed on an old machine or a particular part can be replaced with a new part with improved features.
When a machine or system is retrofitted, it acts as a smart machine and it generates plenty of data. This data is being gathered for the analysis. Implementing the ideas based on this data improves the productivity and efficiency of the machine’s work as well as increases the total lifespan of the machine and reduces the amount spent on the machine’s maintenance.
Quite a list of benefits:
- Huge cost savings
- Faster recovery after maintenance breaks
- Reduced number of errors/quality deviations in the production
- Increased safety at the factory
- Valuable analytics that helps to prevent downtime
Here is a look at the real-life examples.
Bosch installed its IoT (internet of things) gateway on a 300-kg cast-iron lathe, the production of which started in the 19th century.
The connected system consisted of sensors, software, and IOT-compatible industrial controls. Via these solutions, the team could track and monitor the condition of the lathe in real-time and even optimize its operations.
Dr Werner Struth, Bosch management board member responsible for industrial technology and manufacturing coordination, commented the following way:
“This is the only construction of its kind in the world. It shows that even ancient machines can be connected quickly and easily with the IoT gateway.”
If these sensors are compatible with the machines that are old, there should be no obstacles on the way of spreading retrofitting for the ‘younger older machines’. Well, in fact, there are some, and we are going to speak of it in the next section of the blog post, while there is another example of retrofitting applications.
Ypsomed is a healthcare company headquartered in Switzerland that produces several hundred million products a year and meets the highest medical technology standards.
Recently, Ypsomed Group and Harting became partners in a development project. They’ve managed retrofitting the legacy protocol plastic injection moulding machines with an integrated Industry 4.0 digital control system.
An important element of Industry 4.0 is the ability to apply digitisation to the production environment by adding more intelligence to existing processes.
Taking a digital retrofit approach allowed the speeding up of the existing processes for minimal cost over a short period of time, resulting in a fast return on investment and immediate productivity gains.
Due to the high proportion of individual plastic components in its products, Ypsomed possesses a large number of plastic injection moulding machines in its production plants.
Their partner’s retrofit began with Harting’s Edge Computer MICA being installed and programmed as the protocol translator. Now the data transmitted via this protocol comes straight to a factory-wide ERP system and becomes available for the analysis.
Challenges of Retrofitting for Industry 4.0
The global Industry 4.0 retrofit solutions market is a multi-billion dollar yet to become a popular option amongst manufacturers. Everybody realizes that connecting traditional machines with smart technologies and with each other is not an easy task.
So carrying out the retrofitting process should be knowledge-based in order for the process to become optimized.
There are not so many companies that have gained experience in the sector. So you should carefully select a software supplier in order for the process of retrofit to go smoothly and lead to optimization.
If you’re looking for a software provider for your retrofit operations, Elinext is ready to help you with any type of software that would enable your manufacturing data gathering and analysis.
Security becomes an issue here as well. The protocols should securely transfer data after the introduction of the new elements to an old system. As the network is connected, one weak spot can expose the data and make the network susceptible to cyber-attacks.
Updating a protocol with continued security and assessing the risks is the key for all your efforts to not go in vain.
Retrofitting of Buildings (Crazy Numbers Inside)
Buildings in the US still have enormous potential for energy efficiency improvements that can be successfully realized in the bank account—not because we lack the technology, but because policy and retrofit implementation often lag behind existing capabilities (many marketed products are far less efficient than best-in-class options).
So what can retrofits actually achieve?
- Energy savings: Comprehensive (“deep”) retrofits of commercial buildings are typically designed to deliver whole-building energy savings of ~10–40%, depending on scale and original condition.
- Deep retrofit benchmark: Federal guidelines define a deep energy retrofit as a renovation that reduces a facility’s energy consumption by at least 40% through an integrated, all-systems approach.
What kind of savings and ROI can you expect from retrofits?
- According to the latest US CBECS data (2018), space heating alone accounted for approximately 32% of commercial building energy consumption; ventilation and lighting each accounted for approximately 10%, which is why HVAC, control, and lighting systems are such consistent winners in retrofits, according to the EIA.
- In offices in particular, appliance energy consumption can average approximately 30%, so standards for control systems and equipment may be much more important than expected.
What to Expect in 2026
- Many retrofit packages can pay for themselves in less than 5 years in real-world projects (especially when combining “quick wins” like lighting and control systems with longer payback periods).
- Examples of “quick” economic solutions are based on the laws of physics: upgrading to LED fixtures significantly reduces power consumption (e.g., ~12-22W vs. ~28-56W for a typical 4-foot fixture), so lighting is often the first step Stantec owners take.
- For electric HVAC systems, upgrading to a variable frequency drive (VFD) is typically estimated to have a payback of ~1.5-3 years in many applications (depending on the specific facility, but often attractive).
Seems like easy money? Well, at least it is worth the attention of investors if the estimations are correct.
But what kind of retrofits within a building could one make?
Well, low-cost, minor retrofits that are easy to implement and offer good value for the money and effort invested could include sealing with spray foam, adding insulation and upgrading the lighting systems,
All the way to deep retrofits, such as replacing the roof, or significantly rearranging windows, replacing the heating or ventilation systems.
That significantly increases the energy efficiency within the building and looks like a promising investment field.
The world has 1.6 trillion square feet of building stock, 99 percent of which is not green.
Retrofitting addresses how heat and cold are escaping or entering the building, the systems that cool or warm inhabitants, and how spaces are illuminated. It ultimately improves the experience of being inside the building.
By investing in retrofits that make your factory, or building more energy-efficient, you can achieve the following:
- amazing impact on lowering your energy costs
- reduce your maintenance requirements
- create a more pleasant interior environment for your occupants (buildings)
- increase the value and productivity of your building
- reduce your environmental footprint.
In smart manufacturing, legacy equipment limits data-driven decision making. Our industrial retrofitting services integrate IoT sensors and software, connecting legacy machines to modern platforms. This approach reduces downtime, increases efficiency, and delivers measurable cost savings for manufacturers facing digital transformation challenges.
Conclusion
Retrofitting services and retrofitting buildings are driving the smart manufacturing trend, offering rapid ROI and sustainable development. For example, Schneider Electric and Nestlé achieved a 20% reduction in downtime and a 340-ton reduction in CO₂ emissions in one year. By 2026, the IoT market in manufacturing will reach $87.9 billion, and retrofits can save up to 77% compared to new construction while reducing emissions by 50–75%. These results highlight the critical role of retrofits in ensuring manufacturing is future-ready.
