Many ships and marine installations utilize three-phase power systems to distribute load efficiently. The RLGT’s 440 V, 3-phase design allows it to integrate into common shipboard power architectures. This alignment reduces the need for specialized transformation or conversion equipment.

Key Design and Installation Considerations

To maximize the performance and lifespan of a marine floor standing AC 4 Ton RLGT, designers and engineers must address several critical considerations:

Location and Vibration Isolation

  • Floor mounting and structural support: The indoor and outdoor units must be anchored to reduce movement and vibration.

  • Vibration damping: Use anti-vibration mounts or pads to isolate the unit from the ship’s structural vibrations.

  • Air intake and exhaust: Ensure unobstructed airflow, avoid re-circulation of hot exhaust air, and allow clearance for maintenance access.

Corrosion Protection and Coatings

  • Material selection: Components near the exterior should use marine-grade aluminum, stainless steel, or coated metal to resist salt corrosion.

  • Protective coatings: Coatings like epoxy, polyurethanes, or specialized marine paints prolong life.

Air Ducting and Distribution Layout

  • Duct length and bends: Keep ducts as short and straight as possible to minimize pressure drop and fan load.

  • Diffusers and grilles: Use corrosion-resistant diffusers and plan layout for balanced airflow.

Condensate and Drainage Management

  • Proper drainage: Design condensate lines with adequate slope, traps, and sea-safe discharge paths.

  • Corrosion-resistant piping: Use corrosion-resistant piping (e.g. PVC, coated copper) for drainage.

Integration with Shipboard Controls and Monitoring

  • Remote monitoring: Ideally, integrate temperature, current, and fault monitoring with the ship’s central control system.

  • Protection devices: Overload protection, surge suppressors, and phase monitoring guard against power anomalies.

Maintenance Access and Serviceability

  • Accessibility: Plan access panels and clearance to service internal components, filters, and controls.

  • Spare parts: Keep essential spares (filters, sensors, capacitors, fans) on board to reduce downtime.

Compliance with Marine Standards

  • Ensure the system meets maritime certifications such as marine HVAC standards, electromagnetic compatibility, fire and safety codes, and classification society requirements (e.g. ABS, DNV).
