The CPAC RH-Pro9 Rapid Heat Sterilizer

Autoclaves have always been a unique piece of machinery. The constant evolution brought on from each advancement in medical tech has made the autoclave into a powerful tool for practices worldwide. Further research over the years has even brought along new methods of sterilization that became the standard in what we use today. Steam sterilization, ultrasonic cleaning, gravity cycles, vacuum cycles, etc. The ways in we sterilize now have changed the way we look at autoclaves. But there’s one type of sterilization that, for a while, sort of fell by the wayside for a couple reasons. HVHA sterilizers weren’t as prevalent for a while until they got a much needed upgrade. And in this article, we’d like to talk about the company that did exactly that, CPAC and their RH-Pro9 Rapid Heat sterilizer. 

Before we get into that, let’s first go over what HVHA means and why some probably don’t know much about them.

What is an HVHA Sterilizer?

HVHA is an acronym describing a very specific type of sterilizer or sterilization, it stands for High-Velocity Hot Air. This type of sterilization, basically dry heat, hasn’t really been prevalent up until recent years. Even being deemed the “orphan-child” of thermal technologies. It worked quite well for what it was, but compared to other sterilization methods, it was very slow. It took the longest amount of time to achieve microbial inactivation among other types like steam sterilization. And there were also issues with temperature compatibility with instruments back in the day. But due to recent advancements in both the dry heat technology and developments in instrument materials, dry heat sterilization is making a resurgence. 

Dry heat utilizes moving air as fluid to transfer heat from the air to medical instruments. They sterilize by transferring heat to microorganisms, damaging their DNA and enzymes and rendering reproductive functions useless. Like other types of sterilization, they have set sterilization cycle times for wrapped and unwrapped materials. And the cycles are broken down into the cycle time and the processing time needed to reach proper spore kill temperatures. 

And the subject of this article, the CPAC RH-Pro9, is one of these latest advancements that is bringing dry heat sterilization into the modern age.

The CPAC RH-Pro9 is a welcome addition to any practice due to its lengthy list of accommodations and benefits. With its High-Velocity Hot Air sterilization system, this sterilizer uses the air in the chamber to properly sterilize your tools. With programmed settings that can accommodate instruments that can handle high heat, or low heat cycles for your more delicate tools. And with a heat system that doesn’t use steam or water like the Pro9 has, the drying cycle is significantly shorter, resulting in the longevity of your instruments. Even with all of these features, the COVID-19 pandemic still called for a greater emphasis on sterilization. So the RH-Pro9 has a specialized cycle that can sterilize your N95 masks for reuse in case of a supply shortage. 

That’s not all, some other benefits of the CPAC RH-Pro9 include:

  • FDA-Cleared 6 Minute Cycles (Unwrapped)
  • FDA-Cleared 12 Minute Cycles (Wrapped)
  • Smaller Cabinet-Ready Size (1163 Cubic Inches)
  • Uses 85% Less Energy Than Steam
  • Non-Corrosive Sterilizer Environment
  • Full 3-Year Warranty
  • Waterless Sterilization with No Chemicals
  • Convenient Smaller Size — Three Instrument Trays

Final Thoughts

The field of sterilization in autoclaves has constantly evolved with the changing times. While advancements have been made in various sterilization methods, such as steam and chemical sterilization, there was relatively little discussion around High-Velocity Hot Air (HVHA) sterilizers for a while. However, CPAC has brought HVHA units back into the spotlight with their RH-Pro9 autoclave.

This innovative autoclave offers a range of impressive features, including rapid and efficient sterilization through the utilization of high-velocity hot air technology. The RH-Pro9 autoclave also boasts a user-friendly interface, precise temperature control, and programmable cycles to meet the specific needs of different instruments and materials. With its reintroduction of HVHA units, CPAC’s RH-Pro9 autoclave ensures that dental practices have access to cutting-edge sterilization technology that enhances efficiency, reliability, and patient safety.
