Essentials Injection Odorizer

Economical Odorization

Welker’s low-cost, proportional to flow injection odorization system for applications with low odorant usage that do not require direct odorant measurement.

The Right Fit

Compact Footprint

Where space is at a premium, the Essentials™ will fit right in. Whether it’s equipped with a 10- or 30‑gallon odorant supply tank, the entire system comes mounted on a 24” x 28” skid.

Far Out

Remote Access

When on-site monitoring of the Essentials™ at the LCD display isn’t practical, conveniently monitor system performance from the control room via a Modbus connection. For locations without an electrical supply, a solar panel can be added to power the Programmable Logic Controller (PLC).
