Hello,
I have a new solution for bubble hoods, Delta Suits, and powered visors. It is called a Hurricane Hood. We used them last outage season for steam generator nozzle dam installation at Vogtle and Diablo Canyon. They were also used for cavity decontamination at Diablo Canyon. We did not have any heat stress issues or PC events. The great thing about them is they provide the user with lots of air (33 CFM) which is more than the PAPR Delta Suit and
5 times more air than power visors or PAPRs WITHOUT any hoses and breathing air system.
There are 2 models: Category 2 (CAT-2) and Category 3 (CAT-3).
The CAT-3 is perfect for steam generator entries……yes, I said steam generator entries! I would like to see you get through a 16” S/G manway with a PAPR on! They have a high speed blower on the top of the hood that blows filtered air down the front of the hood (great for defogging!) and into the suit for cooling. This model can also be supplied with a wireless color camera so you can monitor the actual work the worker is performing. It is a good ALARA solution for limiting HP coverage in certain areas and can be used for QA monitoring of the actual work activities too so they do not need to be in the area.
The CAT-2 uses the same high flow blower and filter system as the CAT-3. The CAT-2 is mounted on the upper back like a back pack and weighs less than 2 lbs. The air is blown from the back of the hood down the front of the hood and into the suit for cooling. This model is great for control rod drive maintenance, cavity decon, etc. The CAT-3 can actually be configured as a CAT-2 by removing 2 thumbscrews for the blower unit and attaching it to the belt pack for the CAT-2.
They are sold as anti-contamination devices like power visors and not as respirators.
There is a lot more information on the website including brochures, pictures, and news:
