GPL Z9000

GPL odorant injection system

Please note that the GPL Z9000 has been replaced by the GPL 750 Odorant Injection System.

Natural Gas Odorizer

The GPL Z9000 offers unmatched simplicity and ease-of-use as every action is intuitive and predictable. It is a proven system that works reliably in many problematic areas including major cities with seasonal winter weather hazardous conditions. The Z9000 performs consistently and repeatedly with minimal downtime, and because of its extensive communication features, it can accommodate even remote locations. Virtually every part of the injector can be handled remotely. Plus, having only two moving parts exposed to the odorant, maintenance and operation are simple. Its simplicity, ease of operation and small footprint that make the Z9000 ideal for urban city gates as well as remote gas well applications. It is also ideal for sites where flow rates vary widely, whether daily or seasonally, as it can switch from automatic to batch mode at a user-defined gas 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.

About GPL Odorizers

GPL Odorizers (formerly Sentry Equipment and Zeck Systems) manufactures eco-friendly odorant injection systems for natural gas and other gases.

What makes us Different

GPL Odorizers strive to provide environmentally friendly solutions to the odorization process. Our systems are self-contained and do not discharge gas into the atmosphere which improves safety, saves pipeline gas and reduces odor at the unit which equates to lower leak call complaints.

The GPL Odorizers also have fewer moving parts than the leading competitive odorization systems; meaning means less maintenance over the life of the unit.
