Ask each bidder to state the filter arrangement, stage ratings, design face velocity and expected differential pressure at clean and dirty conditions. Compare offers against your dust profile, not just against each other, and check that the stage ratings quoted match the unit that will actually ship.
USP&E as Your Guide for Turbine Inlet Design
Soil data decides the design. Commission a site-specific geotechnical investigation with dynamic soil properties, groundwater levels and settlement predictions. Poor soils may need piles, ground improvement or a larger mat, and those choices take time to design and build, so they belong at the start of the schedule. Your gas turbine generators also need anchor bolt templates, grout specifications and embedded items fixed before the pour, because a misplaced bolt costs weeks.
Start With Your Site’s Dust Profile
Base the detector layout on a hazard study of your site. Identify where gas could leak and accumulate, where fires could start and how wind and ventilation move gas. Then place gas, flame and heat detectors to cover those areas, and check coverage with mapping rather than rules of thumb.
Agree voting logic carefully. Requiring two detectors to confirm before shutdown reduces nuisance trips, while a single high reading can still raise an alarm. The right balance protects your people without stopping healthy gas turbine generators unnecessarily.
Design Pulse Cleaning, Hoods and Changeouts
Pulse-cleaning systems need dry compressed air, a cleaning sequence and controls that respond to differential pressure. Weather hoods and drainage stop rain and snow from soaking filters. Plan access platforms and lifting so your technicians can change filters safely and quickly, and store spare filters where dust and moisture cannot reach them.
Set differential-pressure alarms and trips, and record a clean baseline during commissioning. Natural gas engines on the same site need sensible inlet filtration too, though their air volumes are smaller. A changeout plan tied to differential pressure and season keeps your gas turbine generators performing year-round.
Bridge Units and Larger Blocks Need the Same Discipline
Write protection coordination into your contracts as a deliverable with a deadline, not a task for whoever commissions the plant. Require short-circuit, coordination and arc-flash studies before your equipment is finalised, because study results can change breaker ratings, CT ratios and relay types.
AI and hyperscale campuses should also read live data centre power solutions. This site remains inventory-led station discovery — sister datacentergenerators.com owns the DC-only educational lane. Industrial and mining programmes stay here with the same shortlist discipline and EPC wrap.

Your path from first call to reliable power
If gates are rushed, defects surface after handover, warranties get argued over, operators inherit a plant they do not trust and your availability targets slip from the first month. The cost of a missed proof is always higher later.
- List dust profile, filter stages, pulse-clean interfaces, and which inlet loops must be proven before energisation is released.
- Integrate stage ratings, changeout plans, differential baselines, and O&M change-control into one filtration matrix.
- Complete permits, funding, insurance agreements, and commissioning rehearsals before final equipment selection.
Common questions
Why finish inlet air filtration design before energising new gas turbines?
USP&E finishes filtration design first because the filter house decides how much dust, salt and moisture reaches the compressor. A poor match fouls the compressor quickly, raises differential pressure and cuts output in the first dusty season, forcing rework after the unit is installed.
What site data does an inlet filtration design need?
USP&E asks for dust concentration and particle size, seasonal storms, coastal salt, humidity, fog, insects and nearby dust sources. That profile decides filter stages, pulse-cleaning or static filters and whether moisture separators are needed, so the design suits your actual air rather than a generic site.
Can a remanufactured GE Frame 6B meet modern filtration needs?
USP&E can upgrade the inlet system on a remanufactured GE Frame 6B where needed. Its existing filter house, wash history and records are reviewed with the inspection scope, and new stages or weather hoods are added if your dust profile demands better protection.
What belongs in a filtration evidence pack?
USP&E includes the dust profile, filter arrangement and stage ratings, face velocity, clean and dirty differential pressure, pulse-cleaning design, weather hood details and the changeout plan. Commissioning adds the clean baseline, so later readings show exactly how fast filters load.
Why owners choose USP&E
USP&E is a full-service engineering, EPC and O&M company, not a broker. One team designs, builds and runs your plant, so nothing falls between contracts.
