Thanks to their critical role in sterilization, autoclaves are indispensable in various industries, such as breweries. However, autoclaves can also significantly contribute to operational expenses. Fortunately, for breweries, there will automatically be a big cost saving since you won’t have to outsource your sterilization anymore (or waste an employee having them babysit a pressure cooker).

In addition to those savings, an autoclave can further reduce operating costs in your brewery when it is running efficiently. In addition to lowering operational costs, improving autoclave efficiency can enhance your brewery’s overall productivity and sustainability, leading to higher revenue, more profits, and happier customers.

Understanding Autoclave Efficiency

Autoclave efficiency involves optimizing energy and water usage while maintaining effective sterilization. Achieving this balance requires attention to the autoclave’s design and how it is utilized within the brewery. Here are some tips for increasing autoclave efficiency in your brewery to lower operating costs.

1. Regular Maintenance and Calibration

Regular maintenance and calibration are essential for keeping autoclaves running efficiently. Over time, components such as gaskets, valves, and sensors can wear out or become misaligned, leading to inefficiencies. Ensuring that these parts are in good condition can prevent energy and water waste. Additionally, it’s important to regularly clean your autoclave to keep it in top condition at all times.

Maintenance Tips:

  • Schedule routine inspections and servicing.
  • Replace worn or damaged parts promptly.
  • Ensure sensors and gauges are accurately calibrated.

2. Optimize Cycle Loads

Loading your autoclave more effectively can highly impact energy and water consumption, leading to potentially significant cost savings. Both underloading and overloading your autoclave can lead to inefficient cycles. By optimizing load sizes, breweries can maximize the sterilization capacity per cycle, reducing the total number of cycles needed. You can further reduce waste by investing in a portable autoclave since you won’t have to waste energy and water on half-full loads.


Best Practices for Loading:

  • Avoid overloading to ensure proper steam penetration.
  • Use load configurations that allow for optimal steam circulation.
  • Utilize accessories like loading racks to organize items effectively.

3. Upgrade to Energy-Efficient Models

Older autoclaves may not have the same energy-efficient features found in newer models. Investing in a modern, energy-efficient autoclave can lead to substantial long-term savings. Look for models with advanced vacuum systems, efficient steam generators, and programmable control systems.

Features to Look For:

  • Energy-efficient steam generators.
  • Advanced vacuum systems for quicker air removal.
  • Programmable cycles to match specific sterilization needs.

4. Utilize Standby and Eco Modes

Many modern autoclaves come equipped with standby or eco modes that reduce energy consumption when the autoclave is not in active use. Utilizing these modes can prevent unnecessary energy use during idle periods.

Implementation Tips:

  • Train staff to use standby and eco modes correctly.
  • Program autoclaves to enter standby mode automatically during long periods of inactivity.
  • Monitor energy usage to ensure these modes are effectively reducing consumption.

5. Implement Water-Saving Measures

Autoclaves consume a significant amount of water, especially during the cooling and vacuum phases. Understanding what type of water to use for your autoclave and implementing water-saving measures can reduce both water and energy costs.

Water-Saving Strategies:

  • Use water recycling systems to reuse cooling water.
  • Install flow restrictors to limit water usage.
  • Regularly inspect and maintain water lines to prevent leaks.

6. Optimize Sterilization Cycles

Different items require different sterilization cycles, and using a one-size-fits-all approach can lead to inefficiencies. By optimizing sterilization cycles based on the type and volume of items being sterilized, breweries can reduce cycle times and energy consumption. Refer to our helpful guide for sterilizing brewery equipment. And if you are ever in doubt, refer to your autoclave manual to ensure you are optimizing it based on your sanitation needs.

Cycle Optimization Tips:

  • Categorize items and assign specific sterilization cycles.
  • Use shorter cycles for less critical items.
  • Regularly review and adjust cycle parameters based on usage data.

7. Employee Training and Awareness

All brewery staff members should be knowledgeable about autoclave efficiency practices to avoid inadvertently adding operational costs. Proper training can help prevent common mistakes that lead to inefficiencies. Make sure everyone at the brewery understands the importance of correctly operating the autoclave, even those who are not expected to use it regularly.

Training Focus Areas:

  • Proper loading techniques.
  • Correct use of standby and eco modes.
  • Regular maintenance procedures.

8. Monitor and Analyze Performance

Regularly monitoring and analyzing autoclave performance can help identify inefficiencies and areas for improvement. Use data logging and reporting tools to track key performance indicators such as energy consumption, cycle times, and maintenance history.

Monitoring Strategies:

  • Install energy and water meters on autoclaves.
  • Use software tools for data logging and analysis.
  • Conduct regular performance reviews and adjust practices accordingly.

9. Explore Alternative Sterilization Methods

Depending on the items being sterilized, alternative sterilization methods such as hydrogen peroxide vapor, ethylene oxide, or dry heat sterilization may be more efficient. At the same time, certain brewery equipment, such as kegs, may not fit in an autoclave and would be better sterilized using a different method. Evaluate these methods based on your brewery’s specific needs and the types of items being sterilized.

Evaluation Criteria:

  • Energy and water consumption.
  • Cycle times and throughput.
  • Compatibility with items being sterilized.


Improving autoclave efficiency is a multi-faceted approach that requires continuous attention to maintenance, operation, technology, and training. By implementing these strategies, breweries can reduce operating costs, enhance sustainability, and maintain effective sterilization processes. 

Regularly reviewing and optimizing autoclave use ensures that your brewery remains both cost-effective and compliant with industry standards. Embrace these practices to achieve a more efficient and economical sterilization process in your brewery. If you’re looking for the right autoclave for your brewery, we’d love to help!
