Anyone know what ppm level is a good place to start when sanitizing a DI recirculating system? I have watched our DI service do the sanitization process many times, but I don't know the level of hydrogren peroxide necessary.
Thanks.
We have a small (20 gallon) electric boiler which we feed with DI water. At first we had problems with false low-level signals. The system uses a resistive probe to detect for presence of water and the DI water had high enough resistivity to make the boiler think there was no water present. The...
I had a similar problem in which I wanted GFCI protection (even though it's not required by NEC) for workers using portable equipment with VFDs in a wet area. I purchased the Bender GFCI devices and they work fine. We haven't had any nuicance trips.
Then I noticed the VFD manual specifically...
You can buy a kit to identify metal types. The ones I have seen in MMC cost from $300 to $700 and can identify almost any kind of steel and even different kinds of stainless steel.
