That's the nature of the beast. We have to install catalytic heaters on these installations to keep the regulators from freezing up due to the bleed.
Becker makes non-bleed controls. Actually, they bleed, but the gas is exhausted into the outlet line.
There are other non-bleed (or minimal...
Thanks! I could not find that page on their Website, though I did see some reference to 48 VDC.
Their FAQ seemed to indicate that these were not suitable.

As an EE, this is embarassing, but I don't work with electrical circuits much so ...
I am designing a DC distribution circuit for a meter house. We have a 24 VDC battery charger (Input: 120 VAC) that feeds DC circuits and a set of batteries. If we lose AC to the building (thus, the charger)...
HgTX brings up a good point. You certainly wouldn't be on the Popularity list if you started reporting every unauthorized stamp/signature that you knew of. In fact, that could be considered "whistle-blowing" and you could lose your job. Then, you could only report those whom you didn't care for...
Wow! Thanks for the support!
Before I had my P.E., I signed a vessel drawing that I didn't remember checking. The Project Manager was in a hurry to get a bunch of documents out and told me that I had checked it, but he didn't have time to get the check copy out.
Well, as it turned out, I did...
I really don't use my PE license much around here, since almost everything we do is for internal use only. However, an engineer (not PE) came to me with a design that had to have a PE stamp on it.
Of course, the drawings had to go out today (Friday before Labor Day weekend). I basically turned...
I've been indirectly involved with a couple of Reverse Auctions. The biggest problem that I see is that you have little control over the technical content of the bid. i.e., while bidders are lowering their price, what are they deleting? It could be that they are planning on using a lower quality...
I agree with felixc - it's the current. There are probably some standards for medical equipment you'll want to check out, or maybe contact a manufacturer.
I remember something like 0.100 - 0.200 Amps will cause fibrillation of the heart and will likely kill if it is not stopped quickly. Current...
Speaking of "melting pistons":
I have a friend that ran his Harley at Bonneville a couple of years ago. On the return run, he noticed he lacked power. That was his last run of the week, so he packed up the bike and went home.
When he removed his front cylinder, there was NO piston. He had a...
No, compression ratio is the same: about 9.5:1. That's because I used KB DISHED pistons, which require no head work. KB suggested the 3 degree retard setting.
Most people have said their temperature went up slightly (10-20 degrees F), if at all. I had high temps before the conversion, though...
I agree that the bypass line allows easier maintenance (usually), but OilBoiler said the budget was "quite tight". Unless the piping configuration allows you to install a bypass line (say at an elbow), it could be expensive to do.
You may still have to install valves to isolate the line. You...
This looks like you want two exclusive things from your valve - ability to handle dirty fluids AND noise / cavitation reduction (at a high pressure drop, no less).
TD2K's comments on using ROs are good. You crude is still dirty, but you may not need the Cavitrol trim.
You could also add a...
A Management Question
Say I hired a young man, for his first job, and he's been on the job two weeks. He's eager to learn, does his job, and looks promising. We'll call him Johnny.
Now say another manager, same level as me, wants our senior manager to fire Johnny. This other manager has been...
OK.
I think the PMP is most valuable to PMI, for it makes them money. A lot of it. Not only do they make $$$ from fees, the trainers for the PMP exam charge hundreds of $$ so you can pass it. Then, you have to have (too) many hours of "education" required to maintain your certification, and...
