Doosan Natural Gas Generators With Paralleling Capabilities

Doosan Portable Power has introduced paralleling capabilities for the NG225 and NG295 models of its natural gas generator product line, suited for applications such as 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 can help users avoid downtime while still achieving acceptable emissions levels by consuming wellhead natural gas as a fuel source. Doosan Portable Power natural gas generators use 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,” said Todd Howe, global generator products manager. “A standard generator is only able to monitor its own operating conditions and remain within the limits of its own operating conditions.”

The paralleling models also include the 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 enclosed to protect against harsh weather, possible damage during shipping and vibration that would occur if attached to the drawbar.

The generators are equipped with an automatic dual-fuel switch, allowing it to operate on natural gas, as well as propane from an external tank. This ensures continuous generator operation if wellhead gas flow is interrupted or unavailable.

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. For durability, the generators are built on heavy-duty skid bases, have a 14-gauge, galvannealed steel enclosure and rugged running gear for easy towing.
