Why Choose ERGIL Coalescing Filters?

Superior Separation Performance

Multi-stage filtration removes free water down to 150 PPM while achieving particle counts to ISO 15/13/10 cleanliness levels. High-efficiency coalescer elements agglomerate submicron water droplets for gravitational separation, while precision filter media captures solid particles down to 1 micron.

Simplex Design Advantages

Single-chamber construction provides cost-effective filtration for continuous operations with scheduled maintenance windows. The straightforward design reduces initial investment and simplifies installation, operation, and cartridge replacement procedures.

Process-Specific Engineering

ERGIL engineers each system based on oil viscosity, flow rates, operating temperature, pressure conditions, and target cleanliness levels. We size vessels and select filter media to optimize performance while minimizing pressure drop across the system.

Code-Compliant Manufacturing

All pressure vessels manufactured per ASME Section VIII Div. 1 or EN 13445 standards with certified welding, hydrostatic testing, and NDT inspection. Complete FAT at our ISO 9001 facility followed by SAT commissioning support.

Proven Applications

Turbine lube oil systems, reciprocating and centrifugal compressor lubrication, hydraulic power units, bearing lubrication systems, and industrial gearbox applications across oil and gas, power generation, petrochemical, and manufacturing industries.

Complete System Integration

ERGIL provides turnkey solutions including differential pressure monitoring, automatic drain systems, sample ports, level indicators, and optional PLC control with remote monitoring capabilities. Skid-mounted designs available for simplified installation.

Technical Capabilities

SYSTEM COMPONENTS AND OPERATION

Filtration Process

Contaminated lube oil enters through the inlet diffuser, where bulk water and heavy particles drop into the sump by gravity. Oil flows through pre-filters removing particles above 10 microns, then through coalescer elements where submicron water droplets combine into larger drops that settle to the collection chamber. Final separator elements polish the oil to target cleanliness before discharge.

Core Components

Pressure vessel with quick-opening closure for maintenance access. Replaceable cartridge assemblies including basket pre-filters, coalescing elements, and separator stages. Manifold systems for secure cartridge installation. Differential pressure gauges indicating service life. Automatic or manual drain valves for water removal. Sample ports for contamination monitoring.

Control and Monitoring

Pressure differential indicators show filter loading and signal replacement requirements. Level switches or sight glasses monitor accumulated water. Optional automation includes PLC control, remote monitoring, automatic drain actuation, and integration with plant SCADA systems for predictive maintenance scheduling.

ERGIL ENGINEERING ADVANTAGE

Complete In-House Capabilities

From process simulation to mechanical design, fabrication, automation programming, testing, and commissioning, ERGIL handles all aspects internally. No subcontractors for critical components means consistent quality, shorter lead times, and single-source accountability.

Performance Guarantees

We provide engineering calculations, performance predictions, and operational guarantees backed by factory acceptance testing. Every system ships with complete documentation including P&IDs, equipment datasheets, maintenance procedures, and spare parts recommendations.

Modular and Skid-Mounted Options

Pre-assembled skid systems include all piping, instrumentation, electrical, and controls. Complete factory testing reduces field installation time and startup risks. Modular designs accommodate future capacity expansion or process modifications.

Global Service Network

ERGIL supports installed systems with spare parts availability, technical assistance, operator training, preventative maintenance programs, and field service for cartridge replacement, system upgrades, or troubleshooting support.

Lifecycle Value

Lower operating costs through extended oil life, reduced equipment wear, and minimized unplanned downtime. Energy-efficient designs minimize pressure drop and pumping requirements. Durable construction ensures decades of reliable service with proper maintenance.

Applications Across Industries

Oil and gas production and refining, petrochemical processing, power generation facilities, marine propulsion systems, industrial manufacturing, steel production, mining operations, and any application requiring high-purity lubrication systems.
