GPL Z9000 Odorant Injection System
The GPL Z9000 has been replaced by the GPL 750
The Z9000 odorizer, originally designed and manufactured by Zeck Systems, acquired by Sentry Equipment in 2010, and subsequently by GPL Odorizers in 2015 has been discontinued and replaced by the GPL 750 odorant injection system. The Z9000 was introduced in 2003 as a simple and ventless odorant injection system with few moving parts.
GPL Odorizers offers the GPL 750 as the replacement for the Z9000. The 750 uses the original proprietary drip technology to deliver uniform and precise odorant injection over a wide flow, including no-flow and intermittent-flow applications. This improved design utilizes advanced technology including the Horner Controller which uses open IP addressable pages for secure remote access and control with real-time alarms, offering its users notifications to smartphones.
Order Replacement Parts While Available
GPL Odorizers will continue to support and service the Z9000 units, and we will sell parts for the Z9000 through December 31, 2019, or until parts are no longer available. Please understand that we are seeing increasing costs on many of the Z9000 components, and availability, particularly the RTU components, is out of our control. We encourage all Z9000 owners to order now the proper parts needed to keep their Z9000 units in good working order while parts are available.
We also are aware that the Z9000 original electronics and software are becoming outdated, and with the end of Windows 7 extended support in January 2020, as well as the discontinuation of new proprietary programming on the Bristol Control Wave Controller, it may be prudent for Z9000 users to make preparations to replace their units entirely.
GPL 750 Replacement
If your company chooses to replace your Z9000 with the new 750 unit, your well-maintained tanks, drip mufflers, tubing, and wiring may be used with a new GPL 750. The feedback we have received on the GPL 750 from Z9000 users is that the 750 is more straightforward to operate and maintain, does not require expensive replacement parts, and is more reliable.

Accurate odorization from 1,000 to 750,000 SCFH
The GPL Z9000 is an eco-friendly feature-rich odorizer that helps customers escape the operational complexities associated with other odorizers or the odorization process. The GPL Z9000 excels in low-pressure and low flow odorization of natural gas.
The GPL Z9000 offers unsurpassed simplicity and ease-of-use as every action is intuitive. It is a proven system that works dependably in many challenging areas including cities with hazardous winter conditions. The odorizer performs reliably with negligible downtime, and because of its all-encompassing communication elements, it can accommodate even isolated locations. Nearly every part of the injector can be worked on remotely. Additionally, with only two moving parts exposed to the odorant, operation and maintenance are simple. Its ease of operation, simplicity, and small footprint make this odorizer ideal for remote gas well applications and urban city gates. It is also perfect for sites where flow rates widely vary, whether seasonally or daily, as it can change from automatic to batch mode at a user-defined flow rate.
The GPL Z9000 is direct injection natural gas odorizer that uses differential pressure to force the odorant into a gas stream. The beauty is that it is a self-contained, ventless sealed system, making it environmentally friendly as there is no gas discharged.
Principles of Operation
The odorant injection system is pressurized to a small pressure (ΔP) above the pipeline pressure using regulated pipeline gas or nitrogen. Odorant pressure control is maintained by a pressure regulator to feed a constant pressure to the controller.
When the flow signal determines there is a need for odorant, an isolation valve is actuated, and odorant flows to the metering valve.
The metering valve releases small volumes of odorant to a drip chamber where a specially engineered dripper cone meters 0.02 cc drops on a steady and highly repeatable basis regardless of drip rate.
As the drops pass the optical sensor, they are registered in the controller, and a flow rate is calculated. The optical sensor can accurately record drops as fast as 8/sec, which is well beyond the maximum dosing rate range.
