GPL 750 Odorant Injection System

Brand: GPL Odorizers
When requesting information, please download the Fillable PDF to provide details about your GPL Odorizer use case. Instructions for completing the form are in the footer of the document. Once completed, please upload the document with the Request for Information.
The GPL 750 Odorizer draws from advanced proprietary technology to deliver precise odorization even in problematic conditions. 

Low-volume, intermittent-volume, even no-flow conditions do not impede the unit’s performance. 

The PLC receives flow information and automatically compensates the injection rate to provide uniform odorant distribution.

The GPL 750 excels in low-flow natural gas odorization applications. The odorizer is appropriate for municipalities and small city gate stations. 

The GPL 750 RNG excels in odorizing biogas and biomethane (renewable natural gas) and is for biomethane and biogas producers.

Batch Odorant Injection for Pipelines
  • 1 to 225 PSI (1-15.5 Bar) Standard
  • No Flow to 24 MMSCFD (injection rate of 0.5 lb./MMSCFH)
The GPL 750 replaces the GPL Z9000, which was formerly the Zeck Systems Z9000.
Features
A sealed-loop system means no gas or odorant discharges to atmosphere
  • No smell during operation and maintenance
  • Lowers false leak-call complaints
  • Eco-friendly; better for the environment
Does not use gas to actuate the system
  • Saves pipeline gas
Odorant injection relative to gas flow
  • Eliminates under or over-odorization issues
  • Accurate and reliable odorant injection
High rangeability (high turndown ratio)
  • Odorization of a wide range of flows (even problematic flow ranges)
  • Precise odorant injection relative to gas flow
One moving part with minimal fittings and tubing
  • Simple operation
  • Low maintenance
  • Long-lasting performance
  • No smelly pneumatic pumps to replace or maintain
Industry-leading PLC with large (7”), intuitive, color touchscreen and SD card data storage (Spanish mode available upon request)
  • Easy to learn and operate
  • The data stores on PLC SD Card permitting accessible audit-trail reports for regulatory or company inspections
  • Communicates real-time critical alarms and soft alarms (maintenance reminders)
  • Allows for Modbus (SCADA)
PLC Interfaces with SCADA Systems
  • SCADA systems save time and energy, increase reliability, reduces cost, improves worker safety, higher customer satisfaction, and improves utilization.
Wireless modem
  • Remote communication (using a wireless modem or Modbus) permits real-time mobile alerts and online monitoring to mobile phones and computers to prevent small problems from becoming big ones and speeds up restoration time.
Easy-to-use software provided
  • No additional software required
Class I Division 2, Groups C and D Class I Division 1 optional
  • Adheres to standard
