GPL Odorizers provide an accurate odorant injection of natural gas, propane, and biogas, over a wide range, including problematic no-flow, ultra-low-flow, high-flow, and high-pressure applications. The manufacturer offers two models that provide precise odorization for most applications. The GPL innovative approach does not use gas to actuate the system and has a sealed and ventless design, meaning that no gas discharges to the atmosphere; therefore, there is no smell, lowering leak-call complaints. The GPL units use advanced tech, which saves time and money through remote monitoring, real-time communications, and efficient reporting. The odorization units are simple to use, easy to maintain, save time, and competitively priced.
