Retrofit and Refurbish Tunnel Pasteurizers:

The Benefits of Repairing, Refurbishing, or Retrofitting a Tunnel Pasteurizer by PRO Engineering / Manufacturing Inc.

Tunnel pasteurizers play a pivotal role in the beverage industry, ensuring the safety and quality of products by eliminating harmful microorganisms.

However, maintaining the functionality and efficiency of tunnel pasteurizers is crucial for businesses seeking to thrive in a competitive market. This is where the expertise of PRO Engineering / Manufacturing Inc. comes into play.

Benefits of Retrofitting a Tunnel Pasteurizer: A Wise Investment

  1. Modernization of technology: Retrofitting involves integrating cutting-edge technology, such as automation and advanced control systems, to bring older pasteurizers up to current industry standards.
  2. Integration of automation and control systems: Automation streamlines processes, reduces human error, and allows for real-time monitoring and adjustment of pasteurization parameters.
  3. Enhanced data collection and analysis: Retrofitting can incorporate data analytics tools, providing valuable insights into the pasteurization process for continuous improvement.

Compliance with industry regulations: PRO Engineering / Manufacturing Inc. ensures that retrofitted pasteurizers comply with the latest industry regulations, maintaining product quality and safety.


  • Conducting inspection programs on your pasteurizers
  • Running energy audits on your pasteurizers
  • Replacing your old or worn-out belts with new stainless steel or plastic belts
  • Upgrading your controls
  • Replacing your carry-ways allowing for better belt tracking and longer belt life
  • Replacing your carry-way covers allowing for longer belt life (this is done after the carry-ways are replaced with the new chevron design instead of the old linear design)
  • Converting your walking beam pasteurizers and warmers into flat-mat design reducing can and bottle tipping exponentially.
  • Replacing and improving your spray nozzles reducing clogs and increasing coverage efficiency
  • Replacing your pumps and drives to increase efficiency.
  • Replacing your transfers with PRO/Float™ transfer plates, reducing can and bottle tipping when entering or exiting the tunnel unit.
  • Replacing your filter boxes 


  • Re-zoning for new products
  • Replacing labor intensive transfer plates with tool-less PRO/Float™ full floating transfer plates.
  • Your Retrofit can be completed in as few as five days, but the average is between 7 and 14 days. Multiple shifts around the clock can speed up the process.
  • Retrofit kits are prebuilt at PRO Engineering and shipped complete to the plant. During a scheduled down period, your retrofit is completed.

Retrofit and Refurbish Copper Kettles:

The Importance of Copper Kettles in Brewing

Copper kettles hold a special place in the brewing process. Their ability to evenly distribute heat and their natural antimicrobial properties make them ideal vessels for mashing, boiling, and fermenting worts. Beyond functionality, copper kettles also carry a rich tradition in brewing, adding an element of artistry to the craft.

Over time, copper kettles can show signs of wear and tear. These signs may include corrosion, leaks, dents, and damage to the kettle’s interior lining. While these issues may seem minor, they can significantly impact the brewing process and the quality of the final product. As a brewery owner, it’s crucial to identify these signs early on.

Benefits of Retrofitting a Copper Kettle: Money Well Spent

Retrofitting copper kettles, especially in the context of brewing or distillation processes, can offer several benefits. Copper has been a popular material for kettles and stills for centuries due to its unique properties, and retrofitting existing equipment with copper components can enhance performance and efficiency. Here are some benefits of retrofitting copper kettles:

  1. Improved Heat Conductivity: Copper is an excellent conductor of heat, which means it heats up quickly and distributes heat evenly. Retrofitting a kettle with copper components can result in more efficient heating, reducing energy consumption and saving time.
  2. Enhanced Flavor and Aroma: Copper has a unique ability to interact with certain compounds found in beverages, such as sulfur compounds in spirits. This interaction can help improve the flavor and aroma of the final product, making it more desirable to consumers.
  3. Reduction of Sulfur Compounds: Copper has a natural affinity for sulfur compounds, which can be undesirable in some brewing and distillation processes. Retrofitting with copper can help reduce the presence of sulfur compounds, leading to a cleaner and more pleasant taste.
  4. Corrosion Resistance: Copper is resistant to corrosion and rust, making it a durable material for kettles. Retrofitting with copper components can extend the lifespan of the equipment, reducing maintenance costs and downtime.
