Process Gas Regulators

15% to 30% Savings vs. Distributor Prices                        60% Savings on Pre-Owned Gas Regulators

Through sources and buying power, Critical Systems carries a large inventory of new ‘surplus’ as well as used Regulators for Gas Delivery Systems.  Consequently, we can offer these components for a substantial savings over the distributor ‘street price’.   CSI offers regulators from APTech, Tescom, Veriflo. We carry a wide array of VCR and Compression Regulators in ¼” through ¾”.  Two and four port configurations are available.

New Regulator Inventory

Critical Systems acquires and offers a wide selection of new ‘surplus’ high purity gas regulators from various sources across the country. All inventory is “new in the box”, enabling CSI to offer pressure regulators at a substantial cost savings – typically 15% to 30% less than traditional distributor pricing.

Reconditioned Regulator Inventory

In addition, CSI also offers pre-owned UHP regulators that have been used on professionally decommissioned Inert Gas Systems. As with all of our used inventory, CSI runs these regulators through an inspection procedure including a nitrogen purge, helium leak, and pressure decay checks. Once testing is completed, documented, and double-checked, components are then repackaged for shipment.

CSI’s Reconditioned Gas Stick Offering

CSI also offers reconditioned ‘CSI Certified’ gas sticks at huge discounts over new.  These gas sticks consist of a valve, regulator, gauge tee and an optional ‘new’ filter configured on an easy to mount back plate. CSI procures only inert gas sticks that have been professionally decommissioned from major fabs. These sticks are then reconditioned, certified, and warrantied using the same process used to recondition gas panels and cabinets.
