Pre-Odorization and Temporary Odorization

GPL Odorizers designs and manufactures portable and temporary odorization systems which permit pipelines to avoid disruption of service commonly incurred during construction. Temporary units also are employed during natural gas pipe pickling, pipeline conditioning, or pre-odorization.

GPL Odorizers systems are easy to transport by forklift or pallet jack and fit into the back of most pickup trucks. The unit includes everything necessary for odorizing, including the odorizer, odorant tank, containment, interconnecting valves and a holder for the customer-supplied nitrogen tank for blanket gas pressurization. No actuation gas is required for the odorizer’s operation, simply connect the electrical power, or use an optional battery pack or solar power package.
