Ports & Harbour

Advanced fluid conditioning for high-intensity terminal operations. We target the sub-micron silt and dissolved moisture that bypass standard OEM filtration, ensuring your mobile and static assets maintain peak hydraulic efficiency in corrosive maritime environments.

Nano-filtration for straddle carrier hydraulics to maintain ISO 4406 14/12/9 cleanliness and prevent valve stiction

01

Container Straddle Carriers & Mobile Handling Equipment

APPLICATION

  • Container straddle carriers and rubber-tyred gantries (RTGs)

  • Reach stackers and empty container handlers

  • Ship-to-shore (STS) crane hydraulic systems

  • Terminal tractor and yard equipment hydraulics

THE PROBLEM

  • Salt-laden air causes accelerated oil oxidation and proportional valve varnish

  • Varnish causes 'stiction' — valves fail to shift, creating sluggish or unpredictable actuation

  • Hydraulic lockups during ship-to-shore operations create critical berth congestion

  • Standard 10-micron filters cannot capture the 0.1–3 micron particles driving degradation

DELTA-XERO SOLVES THIS BY

  • Nano-filtration down to 0.1 micron removes varnish precursors before they polymerize

  • Maintain ISO 4406 cleanliness at 14/12/9 or better to eliminate silt-lock and stiction

  • Ensure sub-millisecond hydraulic responsiveness in all container handling controls

  • Extend pump and actuator life by up to 300% through continuous offline conditioning

Continuous moisture and particulate removal for dockside crane gearboxes

02

Harbour Cranes & Dockside Winches - Mobile Harbour Cranes, Heavy-Lift Winches & Planetary Gearboxes

APPLICATIONS

  • Mobile harbour crane slewing and hoisting gearboxes

  • Dockside heavy-lift and bulk-handling winches

  • Ship unloader and grab crane lubrication circuits

  • Port floating crane and barge-mounted crane drives

THE PROBLEM

  • Salt and grit ingression acts as a grinding paste in high-torque planetary gearboxes

  • Particle contamination causes pitting and spalling on gear teeth and bearing races

  • Moisture reduces oil dielectric strength and lubricity, accelerating gear failure

  • Replacing a primary hoist gearbox is a multi-day operation impacting terminal throughput

DELTA-XERO SOLVES THIS BY

  • Provide continuous moisture removal and ultra-fine particulate capture offline

  • Reduce moisture content to below 100 ppm to maintain lubricant additive integrity

  • Strip abrasive fines to sub-micron level, reducing mechanical wear rate by over 80%

  • Transition from reactive break-fix to Condition-Based Maintenance (CBM) strategy

Standby hydraulic conditioning for port linkspans and tidal gates to prevent acid formation and seal failure

03

Linkspans, Lifting Bridges & Tidal Gates - Port Infrastructure, Ferry Ramps & Standby Hydraulic Systems

APPLICATION

  • Linkspan and ro-ro ferry ramp hydraulic actuators

  • Lifting bridges and bascule bridge drive systems

  • Tidal gate and lock gate hydraulic control circuits

  • Port harbour entrance and flood defence gate systems

THE PROBLEM

  • Long standby periods allow moisture ingress via reservoir 'breathing', causing oil emulsification

  • Acid formation (TAN increase) from moisture and oxidation attacks seals and cylinders

  • Degraded fluid causes seal bypass or valve jamming when the asset must actuate urgently

  • Failure during vessel berthing poses severe safety and scheduling risk to port operations

DELTA-XERO SOLVES THIS BY

  • Maintain fluid health 24/7 even when primary assets are powered down

  • Actively prevent TAN rise and maintain high MPC rating through continuous offline scrubbing

  • Guarantee immediate standby infrastructure readiness regardless of interval between uses

  • Eliminate corrosion and acidity-driven seal failure in critical marine infrastructure

High-efficiency fuel polishing for port terminal operating systems (TOS)

04

Port Backup Power & Emergency Generators - Terminal Operating System Power, Reefer Power & Emergency Infrastructure

APPLICATION

  • Terminal operating system (TOS) backup diesel generators

  • Reefer container power and cold chain backup systems

  • Port fire pump and emergency response power systems

  • Harbour authority and vessel traffic services (VTS) backup power

THE PROBLEM

  • Water condensation in bulk diesel tanks enables diesel bug that plugs filters at cold start

  • Fuel instability during long storage causes injector failure under emergency load

  • Carbon soot agglomeration in engine oils increases viscosity and causes high-load wear

  • A failure-to-start at a critical terminal moment has massive operational and reputational impact

DELTA-XERO SOLVES THIS BY

  • Reduce diesel contamination by 99.8% and water by 99.5% in port fuel storage tanks

  • Remove soot and oxidation products from engine oils that standard bypass filters miss

  • Achieve 7–33% CO2 reduction and ensure backup systems meet load-step requirements

  • Guarantee zero risk of 'failure to start' for port emergency and critical power systems
