Sea Water Chiller

General Description

  • FIDEM Seawater Chillers, developed by Aquatech Plus, are precision-engineered for marine and coastal environments where corrosion, salt exposure, and reliability challenges demand robust solutions. Featuring marine-grade scroll compressors, titanium heat exchangers, and anti-corrosion protection, FIDEM chillers offer unmatched durability and thermal performance for shipboard, offshore, and coastal cooling needs.

Key Performance Highlights

Variable Frequency Drive (VFD) for Energy Efficiency

  • The scroll compressor is VFD-enabled, dynamically adjusting its speed to match cooling load — delivering substantial energy savings, smooth operation, and extended lifespan.

Space-Saving Design for Marine Installations

  • FIDEM chillers feature a compact, modular layout perfect for tight spaces such as engine rooms or onboard equipment bays. Options for side or top access simplify installation and maintenance.

Low Noise and Vibration

  • Scroll compressor technology ensures quiet, vibration-free performance, making FIDEM chillers ideal for yachts, naval ships, and offshore platforms.

Titanium Heat Exchanger for Ultimate Corrosion Resistance

  • The evaporator and condenser coils are constructed using titanium — the most corrosion-resistant metal available — ensuring superior performance and longevity in saline environments.

Anti-Corrosion Coatings Throughout the System

  • All internal water-contact surfaces are coated with marine-grade anti-corrosion protection, and key components are built from SS316 or better stainless steel.

Built for Marine and Offshore Applications

  • FIDEM seawater chillers are optimized for continuous-duty cooling under demanding conditions such as:

    • Engine jacket water cooling
    • Power electronics and VFD cooling
    • Marine radar, sonar, and communication systems
    • Seawater-cooled air conditioning and HVAC
    • Chilled water supply for seafood storage and processing
    • Marine aquaculture, fish tanks, and hydrotherapy pools

  2. Compressor Type
    • Scroll compressors offer superior reliability, low noise, and VFD compatibility
  3. Compactness & Installation Footprint
    • Confirm size and access for service in tight engine rooms
  4. Cooling Load Calculation
    • Account for all onboard systems: HVAC, electronics, engines, etc.
  5. Water Quality & Filtration
    • Include strainers or optional deionizers if water has high sediment or biological content
  6. Noise Levels
    • Especially important for vessels with cabins or crew quarters
  7. Power Supply Compatibility
    • Ensure compliance with marine standards (e.g., 440V/3Ph/60Hz or 220V/3Ph/60Hz)
  8. Ease of Maintenance
    • Look for modular design, local service access, and intuitive diagnostics
  9. Controls & Safety
    • Intelligent controllers with alarms for high temp, flow failure, and low water levels
    • Optional RS485/MODBUS integration for remote monitoring
  10. Manufacturer Reputation & Support
    • FIDEM chillers by Aquatech Plus are field-tested across Indian ports, shipyards, and offshore rigs
    • Reliable service backup and engineering support
