RETROFITS

Extend the life of your Kilns and Furnaces with our Retrofit solutions

NUTEC Bickley Kiln and Furnace Retrofits

Our expert team offers broad experience in the design, manufacture and rebuild of kilns, furnaces and ovens, and so will help you to evaluate whether an upgrade could prove more beneficial than a wholesale change in technology.

Sometimes the purchase of a completely new system is not the best option in terms of obtaining the greatest return on investment; instead, repairing the existing system can prove more profitable, depending on the circumstances.

Our upgrade and preventive maintenance services will assist you in keeping your kiln, furnace or oven operating at the same or even better level of performance as when it was originally purchased.

We have at our disposal advanced tools and the latest thermal process simulation technology in order to be able to best advise our clients.

What are the benefits of a properly executed retrofit for industrial furnaces?

By performing a retrofit of the combustion and control system with CCS, the customer obtains clear and measurable benefits:

  • Equipment safety is significantly improved by incorporating components and design philosophies aligned with international standards, reducing the risk of incidents and ensuring regulatory compliance.
  • Operational reliability is enhanced, reducing unplanned downtime and increasing system availability.
  • Greater energy efficiency is achieved through more precise air–fuel ratio control and improved process modulation, resulting in reduced fuel consumption.
  • Increased operational stability is obtained, directly impacting product quality and process repeatability.
  • From an operational standpoint, the customer gains access to modern control systems with user-friendly interfaces that facilitate monitoring, trend analysis, and real-time decision-making.
  • One of the most important benefits is the technical support provided by CCS, ensuring not only proper retrofit implementation but also sustained performance over time—positioning CCS as a strategic partner in the customer’s operation, not just an equipment supplier.

When should you consider upgrading your furnace?

Performing a retrofit becomes especially relevant in the following scenarios:

  • Where the furnace or heating system is not meeting the expected operational objectives. This includes situations where the equipment does not achieve the desired production levels, fails to meet required process quality, or presents deviations that directly impact the final product.
  • When unsafe operating conditions exist, when the system does not comply with globally recognized safety standards, or when incidents, recurring alarms, or findings from internal or external audits have already been reported.
  • Another common scenario is the presence of unplanned downtime caused by failures in the combustion or control systems, affecting equipment availability and generating high operating costs.
  • The integration of new technologies significantly improves the interaction between operators and equipment. Modern control systems provide greater process visibility, real-time data access, and the ability to anticipate deviations before they become failures. This delivers additional benefits that are not always evident at first, but positively impact operational stability, decision-making, and overall process efficiency.

What are the main areas of an furnace that could benefit from an upgrade?

In addition to the combustion and control system, there is also the possibility of performing a retrofit or intervention on the furnace or heating system insulation. At this point, it is essential to clearly differentiate between a repair and a redesign of the insulation system, as the scope, impact, and benefits of each are different.

A redesign of the insulation system

  • Involves analyzing the thermal and mechanical behavior of the furnace to define a more efficient solution adapted to real operating conditions. 
  • In this case, the objective is to achieve a specific performance improvement, whether in energy efficiency, heating time, durability, or operational stability. 
  • It is essential to consider all factors affecting the insulation, such as gas flow, operating temperature, the presence of process-generated contaminants, and possible physical contact or abrasion on the material. 
  • Based on this analysis, a system can be designed that not only minimizes heat losses but also ensures longer service life and reduces the need for maintenance-related downtime.

Corrective Maintenance

  • Consists of replacing damaged insulation material, along with its anchoring system, with new materials while maintaining the original equipment design. 
  • The furnace is restored to its initial condition without modifying its thermal behavior or structural performance. 
  • This type of intervention is usually faster and requires lower investment, but it does not address underlying design-related issues.

Frequently Asked Questions About Retrofits

What Is a Retrofit in Industrial Furnaces?

Performing a retrofit on equipment means modernizing it to improve performance, safety, and operational efficiency without fully replacing the existing system. When referring to a retrofit in the combustion system, it involves redesigning and incorporating more advanced technology to keep furnaces and heating systems operating under optimal conditions over time.

This type of retrofit generally includes the integration of key elements for safety and efficiency, such as automatic safety valves, flow control valves for modulation, next-generation burners, flow measurement systems adapted to the operating fluid, and other safety components such as overpressure valves, regulators, and proportional control systems. It is important to consider that these elements have a defined service life, so their timely replacement is essential to ensure safe and reliable operation.

What Does a Retrofit in Industrial Furnaces Involve?

A control system retrofit involves modernizing the elements that govern equipment operation, such as PLCs, temperature controllers, thermocouples, and ignition and flame supervision systems. By updating these systems, greater operational safety, improved process stability, and a more user-friendly operation are achieved. One of the most relevant retrofits is replacing obsolete control panels with modern systems featuring graphical interfaces, allowing real-time trend visualization, detection of deviations in critical variables, timely alerts, and faster, better-informed decision-making. In summary, a retrofit not only extends the equipment’s service life, but also transforms the operation into a safer, more efficient, and more reliable system aligned with current industry standards.

When Does It Make Sense to Upgrade the Insulation System in an Industrial Furnace?

  • A classic example of an insulation retrofit is replacing refractory brick or castable with ceramic fiber. This change significantly reduces the furnace’s thermal mass, which can lead to substantial reductions in heating time—sometimes by an order of magnitude depending on the application. Additionally, repairs become simpler and faster, improving equipment availability.
  • Another common case is transitioning from layered ceramic fiber systems to ceramic fiber modules. This upgrade improves the anchoring system, reduces the risk of material detachment, and increases insulation durability, resulting in more reliable operation and fewer interventions over time.

Overall, a well-designed insulation retrofit not only improves thermal efficiency but also enhances operational reliability, reduces maintenance costs, and stabilizes the process—making it a key element within a comprehensive furnace improvement strategy.
