As Tier 4 Final machines roll off the production line and onto equipment dealer lots, the cost of replacing aging machines continues to rise. And, while modern emission regulations have created a market for engines that burn cleaner and help reduce pollutants that can harm the environment, the technologies required to achieve these benefits have also added costs and complexity to today’s diesel powered equipment.
Equipment manufacturers are required by law to meet emission standards by introducing Tier 4 Final machines, but many contractors still simply want reliable machines at an affordable cost. Thankfully, the emergence of remanufacturing programs is helping to bridge the gap by giving contractors the option to extend the useful life of aging equipment at a lower investment and with strong returns. Remanufacturing larger air compressors — 375 cfm or larger — is a growing trend across the industry with most major equipment manufacturers offering some form of a remanufacturing program. While each program differs, the general remanufacturing process for most includes a complete restoration of the air compressor from a refurbished sheet metal frame to new wiring harness, filters, fluids and other parts needed to bring the unit back to like new condition.
Each air compressor receives a rebuilt engine of the same tier classification as originally equipped, as well as a factory reconditioned airend. The unit undergoes a thorough inspection by certified service technicians, and usable parts from the original air compressor are thoroughly cleaned and checked again before reassembly. New fluids are added, filters are replaced, and the exterior sheet metal and frame receives a total makeover, including paint removal and recoating. Most manufacturers offer a same-as-new warranty on the package, engine and airend. The warranty provides peace of mind that the customer is getting a like-new unit and reduces the risk that the machine will experience downtime that results in high costs down the road. With the same warranty, performance and aesthetics, the real difference between a new and a remanufactured air compressor is the aprice. A remanufactured unit can typically be purchased at an estimated 20 to 30 percent cost savings compared to purchasing a new Tier 4F model of any manufacturer brand. Considering the sale price of Tier 4 equipment, that could add up to significant cost savings on the purchase price, potentially to the tune of $20,000 – $50,000.
Once the comparable reliability and performance of a remanufactured air compressor have been proven on a jobsite, fleet managers are sending in additional units to be remanufactured. And, other contractors are joining the movement. The result for manufacturers like Doosan Portable Power is a strong increase in demand for remanufactured units in North America compared to 2014 figures. Doosan Portable Power is just one manufacturer experiencing an influx of requests for remanufactured air compressors. Due to increasing market demands, Doosan has doubled its output of remanufactured air compressors annually since the company launched the initiative in 2012.
The increase in total volume has spurred the company to make vast operational adjustments to add capacity in order to meet demand. Availability of remanufactured inventory is another factor driving demand. As manufacturers are challenged with transitioning various product lines to Tier 4F technology, many have existing stock of remanufactured units available for resale. In most instances, customers can also choose to retain ownership of their original air compressor that is then remanufactured and returned to the customer’s fleet. While manufacturers must continue to meet emission standards with Tier 4 Final machines, the remanufacturing program gives contractors the power to choose: Give an aging air compressor a new lease on life at a lower tier level and lower cost; or make an investment in Tier 4F models with advanced features, better fuel economy, less maintenance
STATESVILLE, N.C. — Doosan Portable Power has expanded its lineup of dual pressure and dual flow air compressors with the introduction of the Tier 4 Final–compliant P425/HP375 and HP450/VHP400 air compressors.

STATESVILLE, N.C. — Doosan Portable Power has introduced paralleling capabilities for the NG225 and NG295 models of its popular natural gas generator product line.
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, and therefore should one machine shut down or need to be taken offline for scheduled maintenance, the other unit seamlessly takes on 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 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.”
In addition to a Doosan-installed paralleling solution, the paralleling NG225 and NG295 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 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.
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 in the event that wellhead gas flow is interrupted or unavailable.
Dual frequency and optional voltage make Doosan 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.
All Doosan Portable Power generators are designed to withstand rugged transport and jobsite needs. Built on heavy-duty skid bases, the generators boast a 14-gauge, galvannealed steel enclosure and rugged running gear for easy towing.
Doosan Portable Power offers a full line of mobile generators to meet the needs of any application.

The introduction of the G50 mobile generator marks a size increase in the Doosan Portable Power generator product line. The G50 (51 kVA) replaces the G40 (35 kVA) generator, a change driven by customer demand for higher kVA output.
Another customer-driven feature of the new G25, G50 and G70 is increased onboard fuel capacity for runtimes in excess of 24-hours at any load factor. An optional 48-hour runtime solution is available on the G25 and G70 models. The newly packaged generators are also quieter than previous models, most notably the G25 which features one of the industry’s lowest sound levels at 63 dBA.
“These multipurpose generator models are popular rental items, especially for general construction and event applications where extended runtime without refueling and low sound levels are required,” said Howe.
The new generators also feature enhanced controls for easy operation. The new Doosan engine controller includes a backlit LCD screen for easy viewing of common parameters while analog gauges allow at-a-glance monitoring for operator convenience. Fault codes are displayed in simple text for faster diagnostics and troubleshooting. The new controls are also designed to allow integration of a variety of telematics packages for customers that desire remote monitoring capability.
