He can also get drunk and act a fool from what I’ve heard.
He’s always been professional when I’ve met/interacted with him.

PSI is a terrible company with a lazy non helpful staff that moves at a snails pace. We will never use them again.

It’s funny that everybody hates PSI because they’re so strict…
I like PSI and we have worked with them since the beginning.
I see 3pcerts as a knockoff company that will certify just about anything even if it’s dangerous because we’ve seen it multiple times now. 
So if you can’t pass the PSI cert, which you really should be able to - it’s definitely not hard, then you’ll probably need to go to 3p because, like I said, they will sign off on just about anything.
I’ve even seen systems without PRVs in certain spots that absolutely requires them because it’s sealed off between two valves.
I personally prefer PSI over any other PE because I actually trust their work. They go above and beyond as all certifying bodies should.
I don’t know why they were slow with you guys because we’ve had them upgrade / add to certs overnight without a problem. They’ve always answered all of my questions and we’ve even figured out how to certify things that no one has ever done before in the extraction / refrigeration world.
They just like to follow all of the rules and regulations, which quite honestly, isn’t a bad thing in a new budding industry with the potential of people dying if the systems don’t operate like they should.
All of our systems are PSI certified and we definitely recommend PSI for your lab sign off.

Site glasses can vary on rated operation pressure. The ones we use are 2000 PSI rated and are pretty much bulletproof.

I don’t know if strictness is the issue here, unfortunately. It appears that PSI creates issues for companies that use BZB machines due to what appears to be personal beef with ownership(Boris). If my company lost time and money because the engineering firm I hired has personal beef with someone, I’d be sure to shit-talk them online too. That being said, I personally have not worked with PSI or 3pCertz and can’t speak to their professionalism or skillset. What I can say is I’ve used a Bizzybee(which was 3pCertz Certified) and a Precision(Which was PSI certified). We had a myriad of safety issues with the Precision unit. Just one example that cost a whole batch:
During normal operations, glycerin in a vacuum/pressure gauge drained into the recovery tank and solvent vapor filled the gauge. The mystery glycerin(I hope that’s what it was) mixed with the oleoresin and solvent during recovery destroying the whole run. If they used diaphragm seals on their gauges, or appropriately rated brand name gauges… this would likely never happen.
On the other hand, BZB was rock-solid. Sight glass was very handy and if you are qualified to operate the machine, you’ll never come close to the rated pressures. If PSI has personal beef with BZB, they should refuse the business from clients instead of costing them time and money.

Or dry gauges

IMO liquid filled gauges are generally better and dampen dramatic spikes and valleys in pressure. To be honest I’ve usually seen them fail by leaking their fluid externally, though in a typical bourdon tube gauge I can definitely see how they could leak back into a system, especially one that has a deep vacuum drawn on it

Liquid gauges certainly offer multiple advantages, and are generally considered superior, but they’re not really necessary IMO. You can also run a cheap pressure snubber if you’re really concerned with spikes/pulsating.
Just don’t use the cheap BVV glycerin gauges, or you’ll have a bad time…

I will second the commentary on shitty Precision pressure gauges. That is all

I’ve heard this countless times from so many customers that get tricked into paying a substantial deposit then get told that they won’t approve certain things and pretty much hold the customer’s funds hostage. This is just a bad way to do business. PSI also went around misleading clients that XD was selling counterfeit asme tanks to try and promote only ETS products onto customers. Proved them wrong with ASME reps saying PSI was wrong. Still thinking about whether or not I want to sue them for defamation. At the end of the day, there are plenty of better options out there.

Looks like all the anti competitive slander Matt Ellis liked to spew over the years didn’t really account for much
