What you need to know about paralleling natural gas generators


Doosan Portable Power has introduced paralleling capabilities for the NG225 and NG295 models of its natural gas generator product line. Paralleling natural gas generators are especially attractive for oil and gas exploration, site preparation and water well drilling, where remote locations, emissions regulations and 24-hour production schedules pose challenges for operators.

During paralleling, the generators share the load, meaning that if one machine shuts down or needs to be taken offline for scheduled maintenance, the other unit can assume the full load, preventing any lost production time.

Doosan Portable Power natural gas generators utilize a factory-installed paralleling solution that is built into the machine design. The units include a new control panel and electronically controlled circuit breaker that ensures the machines effectively communicate, bringing the units into synchronization without risk of system failure or machine damage that can occur when paralleling conditions are not precisely met.

The paralleling NG225 and NG295 models also include a number of features that have become synonymous with Doosan Portable Power natural gas generators, such as the patent-pending Onboard Scrubber System (OBSS) that improves machine performance by removing excess dirt and water from wellhead gas. The internally housed OBSS includes a heated drain valve to prevent water removed from the gas from freezing in the hose — an event that could disrupt the flow of natural gas and possibly cause the machine to shut down.

Doosan Portable Power natural gas generators are equipped with an automatic dual-fuel switch, allowing the generator to operate on natural gas as well as propane from an external tank. This ensures continuous generator operation should wellhead gas flow be interrupted or unavailable.

Dual frequency and optional voltage make Doosan Portable Power natural gas generators the most versatile in the market. Operators can select 50 Hz or 60 Hz, with the simple flip of a switch, and choose between 480 volts and 600 volts alternator output.
