Key POD Features

Cellular Telemetry

Multi-channel, battery-operated cellular telemetry unit monitors and reports tank levels to our logistics center for automatic, on-time deliveries.

A top-mounted GPS tracking system working through the cellular telemetry simplifies asset management and when combined with DataOnline™ platform, enables online tracking and mapping, allowing you to see where PODs are and where they have been.

Tamper-Resistant Gas Mixer Unit

Tamper-resistant, non-mechanical mixer cannot be adjusted by field personnel. Two- and three-gas mixers are available offering a combination of pure argon, C-5, C-10 and C-25. It features a test port for on-site blend verification and adherence to AWS specifications.

On-board, Blend Integrity Alarm

The on-board alarm will sound if the mixer reaches the critical low gas pressure point necessary to support blend integrity. When using the available distribution panel, a tethered alarm box can also be set at the worksite to ensure audible notification, even at the busiest facilities.

Uninterrupted Supply Via Switchover Box

The switchover box allows the connection and disconnection of units while providing a seamless transition during POD System changeouts. The pressurized quick-connects ensure product integrity throughout the transition resulting in an uninterrupted supply.
