[labnetwork] Span gauge replacements for gas cabinets

Tue Oct 14 20:01:34 EDT 2014

The Johnston Group LLC from Pleasanton Ca has over 180 of the Air
Products GG450 cabinets and over 100 VMBs instock, and can help with
hard to find parts, including complete cabinets. Expertech and The
Johnston Group are alliance partners, and I would be glad to forward the
list of their material to anyone who would like. As Tom said, since this
is not a sales forum, I am glad to take this offline.

Thank you Dennis!

Hi Greg. We can definitely help here. While we don't have any of the
GG450 systems anymore, we do have every generation from that point
forward, and over 500 gas cabinets and VMBs in stock. Because of this, I
have all the parts you'll need to get back up for as little as possible.
When you're ready for replacement cabinets, we have a cost model that
many in our UGIM group have taken advantage of. As-new warrantees,
on-site commissioning, training, ongoing support. It's a model that is
designed to provide an excellent reconditioned gas cabinet that will
serve all your needs at a price that won't destroy your budget.

This isn't a sales forum, so I'll leave it at that, but if you want to
give me a call I'll get you the parts you need.

Thank you!

Tom

Gregg,

I'd talk to Tom Britton of Critical Systems.  He's on this site, and is
a regular contributor.  They have also refurbished "older" Air Products
gas cabinets for me.  I would expect them to have spares, or could at
least point you in the correct direction.  The "Span" name has been
bought and sold so many times, I'm not sure what banner they're being
offered under now.

I took a look at one of our gas cabinets, we're using a WIKA guage,
similar to this;

Take care,

Hello,

We have older (circa 1992) Air Products GasGuard GG450 single and dual
controller gas cabinets. 

We are using them for SiH4, DCS, PH3 balance SiH4 for various LPCVD
processes.

The Span pressure gauges in the pigtails and VMBs are showing their age
and a few of them have failed, or are no longer able to be calibrated.
These gauge transducers are either in the own weldments connected to the
lines or connected to the lines via VCRs. One gauge is an analog visual
unit on the secondary side of the regulator with an integral transducer
that sends a signal to the controller.

It seems that Span is no longer a viable entity. Does anyone know of a
3rd party company that sources replacements for these transducers?

Thanks,

Gregg Cure`
