This message will be displayed if during a normal Heat Up stage the system determines that there is insufficient water in the Chamber to complete the cycle.

This determination is made by the combined input of two sensors, the Water Electrode and the Safety Thermostat Also if a power failure occurs during the Heat or Sterilization stage after the power returns the system will check the Water Electrode to see if there is sufficient water in the Chamber in order to resume the cycle.

If not the cycle will be aborted, the message LOW WATER will be displayed, and the Cycle Fail indicator will light Possible causes for this message are:
1. Insufficient water entered the Chamber at the beginning of the cycle. Check for proper leveling, a dirty or shorted Water Sensing Electrode, a clogged Water Pump, a partially clogged line or that the Air Outlet Valve is stuck closed
2. A leaky Solenoid Valve, Safety Valve, Air Jet, Door Gasket, Door Bellows or a pipe fitting is allowing water or steam to escape at a higher than normal rate
3. A power down has occurred and on power up if the water Electrode tip is dry the Low Water message will be displayed

more from Bill Smith, cPac CEO:

CPAC’s RapidHeat Pro11 Sterilization of Dental Handpieces The RH-Pro11 Sterilizer incorporates the High Velocity Hot Air (“HVHA”) principle of sterilization which is a waterless, non-corrosive technology and completely safe for the sterilization of most dental handpieces.

Incorporating a higher sterilizer chamber temperature (3750F) that is only a nominal 100 degrees higher than an autoclave, HVHA sterilization has been demonstrated in comprehensive testing not to have any more deleterious effect on dental handpieces than that of steam autoclaves. Because of their high-speed operation, today’s handpieces are made of higher heattolerant materials including “Viton” O-rings and “Torlon” Bearing Cages that routinely operate at continuous temperatures exceeding 4500F.

Additionally, the fiber-optic glass rods of a dental handpiece which have an operating temperature of 9000F are not affected by the RH-Pro11 sterilization environment. A dental handpiece life cycle can actually be extended when sterilized by an RH-Pro11 sterilizer since no water (steam) or chemicals are used in the HVHA technology.

When surveying handpiece repair technicians nationwide we discovered that one of the worst enemies to a handpiece low-maintenance operation is the improper drying of handpieces and the resulting corrosion that moisture causes.

Another concern of infection control practitioners and that of the CDC is the potential cross contamination of an improperly cleaned and sterilized dental handpiece. Bioburden left on a dental handpiece may act as a protective shield for microorganisms in an autoclave. Whereas the same bioburden microorganism may be more easily killed in an RH-Pro11 sterilizer due to its elevated temperature transferring heat faster through surface contact (via heat conduction). In documented independent testing it has been shown that 47% of microbes within a handpiece motor were transferred to a prophy angle.

HVHA technology with its penetrative power can materially reduce microbial bioburden and transmission of microbes to and from the motor. Regarding lubricants used in dental handpieces, most of which are petrochemical based, if the handpiece lubricant is not properly expelled prior to sterilization there can be gumming up of the turbine with the potential for the lubricant to enter the patient which is not desirable. As a preventative measure CPAC recommends that hightemperature food grade lubricants (>5000F, e.g., Super Lube® DRI-FILM) be used for handpieces that are sterilized using the HVHA RapdHeat technology.

When the HVHA RapidHeat technology was originally validated and independent tests conducted for a variety of handpieces and submitted to FDA for clearance, there was found to be no negative impact on the tested handpieces with the tests actually demonstrating a 12-Log kill reduction of spores as required by FDA. CPAC is currently in contact with handpiece manufacturers requesting that they support the HVHA validation of their products and their IFU’s include HVHA sterilization.

According to Bill Smith CEO of cPac (The Cox Rapid Sterilizer Manufacturing Company), some handpiece manufacturers in the past have been concerned about our higher temperature and if it has a deleterious effect on handpieces.  On the contrary, our technology has been documented (tested and proven) not to degrade the handpiece operating life.  Our RapidHeat Sterilizers operate at temperatures significantly less than the 500+ degrees F. operating temperatures of the Viton, Torlon, Radel and fiber optic components commonly used in handpieces. Actually, our RapidHeat sterilization extends the life of handpieces due to the fact there is no moisture or water used in the process to potentially corrode and abrade the key operating components of the handpiece.

Another interesting note of Interest:  CDC Infection control dental guidelines focus on insuring sterilization of the internal mechanism of handpieces which can easily be contaminated with patient material.  Unlike steam, which requires direct contact of steam to sterilize, our RapidHeat technology is a convective/conductive dry heat transfer process that dehydrates and kills microorganisms.  It is much easier to sterilize using RapidHeat than to rely on steam to seek out portals of entry to reach the narrow lumens of the handpiece internal mechanism.  Moreover, unlike our HVHA technology, there is a lengthy drying process for steam required by FDA which is a must for prolonging the life of the handpiece.

Q – I need to purchase the trays and the the tray rack for my Pelton Crane Magnaclave. Where can I get them? It seems that no one has them anymore.

A – The trays and the tray rack are no longer available from Pelton and Crane. however, we found a substitute for you.  Click HERE for further details

Q: I have a Napco sterilizer that worked great for many years. Lately, however, it has started to give me problems, and I am not sure if I should try to repair it, or buy a new one.

A: The Napco sterilizer has been out of production for several years now, and there are no plans to start manufacturing it again soon. Click HERE for the manual in case you need to purchase parts for it.

Q: Is there a Board of Health code in my state (or federal) which requires us to have a printout of every cycle?

A: Yes, several states require you to have a printer and show every cycle time the sterilizer ran, the date, temperature, etc. Click HERE to learn more.

Q: I bought this steamer 7 months ago, and now the gasket rubber has been totally destroyed. Should we need to replace it?

A: What are you cleaning the gasket with? And are you leaving the door a little open when not in use? These problems can cause the gasket rubber to be destroyed. Replace the gasket as soon as possible. Click HERE to buy it immediately.

Q: I own several Cox sterilizers, and is there any dry heat sterilizer that is bigger than the Cox?

A: * A High Velocity Hot Air (HVHA) Sterilizer* is bigger than a Cox sterilizer. It can hold up to six trays of instruments doing complete cycles of unwrapped instruments in six minutes, and bagged instruments in 12 minutes.

Q. I have a question about our sterilmatic autoclave. This is the third one I’ve used and this one has a strange characteristic. We can’t run the autoclave twice in a row without draining and refilling the chamber. Whenever we simply add water to it after a previous run it heats up, comes up to pressure and then the low level water light comes on and stops the unit. We have let it come back to room pressure, drain it and refill with cold water. Any idea what might cause this and fix the problem? Should we be able to do multiple runs once the water is hot and just top off the level in the chamber?

A: It sounds like the low water cut off is getting weak. Is there scale build up in the bottom of the unit? You are supposed to ALWAYS put cold water in unit after every run. It sounds like you have let it run dry a couple of times, weakening the safety. Could it be?
