Doosan Portable Power has introduced paralleling capabilities for the NG225 and NG295 natural gas generators.

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 integrated control panel communicates digitally between the generators, providing each machine the information necessary to synchronize and equally share the load,” says Todd Howe, global generator products manager for Doosan Portable Power. “A standard generator is only able to monitor its own operating conditions and remain within the limits of its own operating conditions.”

Paralleling natural gas generators are ideal for use in oil and gas exploration, site preparation and water well drilling where remote locations, emissions regulations and 24-hour production schedules pose challenges for operators. Paralleling multiple natural gas units together is a means for avoiding downtime while still achieving acceptable emissions levels by consuming wellhead natural gas as a fuel source.

Paralleling generators share the load, so if one machine shuts down or needs to be taken offline for scheduled maintenance, the other unit seamlessly takes on the full load, preventing any lost production time. 

In addition to a Doosan-installed paralleling solution, the NG225 and NG295 also feature a patent-pending Onboard Scrubber System (OBSS) that improves machine performance by removing excess dirt and water from wellhead gas. The 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. The OBSS is fully enclosed to protect against harsh weather, possible damage during shipping and vibration that would occur if attached to the drawbar.
