Free Standing Inert Systems and Gas Panels

Reconditioned – Certified – Warrantied

Up to 50% off the cost of New.

Critical Systems, Inc. has a large inventory of high quality process gas panels and free standing inert auto cross over systems. As with all products bought for our inventory, we start with the finest pre-owned gas systems available, inspecting each piece of equipment prior to purchase. These systems have been professionally decontaminated, decommissioned, purged and pressurized, and are stored in CSI’s controlled environment.

As with all of our gas systems, CSI panels and free standing units are thoroughly tested – cleaned, – replaced (if necessary ) – and calibrated before being CSI certified. Our 50 point checklist ensures that a CSI Certified Gas Cabinet meets the highest standards of purity and quality.  Full analyticals — particle, moisture and oxygen testing — are available upon request.
