Engineered compression without delivery bottlenecks
Gas producers and processors rely on compression packages purpose-built for throughput, emissions, and uptime objectives. Miller Engine rebuilds and configures compression systems with Caterpillar or Waukesha drivers mated to fully refurbished Ariel frames, customized for your suction/discharge conditions. We maintain component inventory and in-house machining so projects stay on schedule—even when OEM lead times stretch months.
From first contact, our applications engineers build detailed performance models capturing suction pressures, discharge targets, volumetric efficiency, rod loads, compression ratios, and horsepower requirements. Clients receive performance curves, vibration limits, and bottle sizing recommendations before fabrication begins. Once a project is greenlit, Miller Engine’s machining and assembly teams execute a documented workflow that mirrors new-asset quality while leveraging rebuilt components to control costs and lead times.
Compression capabilities and configurations
- Gathering systems: Two- and three-stage packages optimized for rich gas streams and variable suction pressures.
- Transmission support: High-discharge-pressure units with precise rod load and pulsation control for pipeline service.
- Vapor recovery & RNG: Smaller horsepower packages with automation tuned for intermittent operation and environmental compliance.
Rebuild and packaging workflow
- Application engineering: We evaluate flow rates, gas analysis, and site conditions to size cylinders, stages, and driver horsepower. Performance curves and rod load calculations are delivered for approval.
- Component refurbishment: Frames, crossheads, and cylinders undergo teardown, NDT, machining, and reassembly. Bottles receive internal coating inspection and repair.
- System integration: We fabricate skids, piping, pulsation control, and instrumentation. Controls can utilize PLC, ADEM, or customer platforms with SCADA-ready communications.
- Testing & documentation: Packages complete mechanical run-in with vibration and temperature trending. Final documentation includes manuals, part lists, and testing records.
- Commissioning & support: Compression specialists travel onsite to oversee installation, alignment, gas leak-down, and operator handoff. Optional remote monitoring packages feed predictive maintenance dashboards and generate automated alerts.
Control systems and automation
- PLC/RTU integration: Implement Allen-Bradley, Siemens, or Emerson PLCs with MODBUS, OPC-UA, or MQTT communication for SCADA networks.
- Safety interlocks: Configure shutdown logic for high discharge pressure, low suction pressure, lube oil temperature, and vibration thresholds with evidence for regulatory audits.
- Telemetry & analytics: Deploy cloud-ready monitoring that logs rod loads, frame vibrations, and thermodynamic data to optimize throughput and maintenance schedules.
- Hybrid/variable-speed drives: Pair electric drives with gas engines to balance fuel consumption, emissions, and power costs across changing field conditions.
Lifecycle services
Our team handles installation oversight, laser alignment, commissioning, and field training. Long-term support offerings cover preventative maintenance, emergency response, and remote monitoring analytics so you can manage operating costs and reliability KPIs.
Lifecycle contracts can include spare parts staging, quarterly performance reviews, and mid-life upgrades such as cylinder reconfiguration or engine repowers. Emergency response teams maintain 24/7 readiness with OEM parts and calibrated tooling, minimizing downtime when unexpected failures occur.
Field-proven deployments
- Midstream operator – Haynesville: Delivered 1,500 HP, three-stage package with Ariel JGK/4 frame and CAT 3516 driver, resulting in a 28% throughput increase and verified emissions compliance.
- RNG plant – Midwest: Reconfigured dual 500 HP packages for intermittent flow, integrating PLC-based automation that reduced venting events by 35%.
- Gas lift project – Permian: Supplied compact 750 HP units with electric-GEN drive hybridization, cutting fuel costs by 18% and stabilizing reservoir drawdown.
