The HVAC systems, process equipment and cold storage systems of large vessels and offshore platforms require centralized, high-flow and long-term stable low-temperature cold water sources. Ordinary split marine air conditioners can only meet single-cabin temperature control, and cannot support comprehensive loads such as ship-wide central air conditioning and industrial equipment cooling. They are also prone to cooling attenuation and unstable operation in high-temperature and high-salinity marine environments.

Winnex Air Marine Water Chiller is specially developed for marine centralized refrigeration scenarios. As the core host equipment of ship central air conditioning systems, it relies on seawater circulation heat exchange and constant cold water output to provide reliable cold sources for ship-wide multi-cabin air conditioning and process cooling systems, serving as the standardized core refrigeration equipment for large ocean-going vessels and offshore projects.

Product Overview

The marine water chiller is an integrated water-cooled centralized refrigeration unit, fully assembled with marine compressors, high-efficiency shell-and-tube condensers, plate evaporators, intelligent electric control systems and circulation protection modules. It dissipates heat through the ship’s seawater main pipeline and delivers constant low-temperature cold water via fresh water circulation pipelines. It can link multiple fan coil units and air handling units to realize ship-wide centralized refrigeration, zoned temperature control and equipment process constant temperature.

The overall structure adapts to extreme marine working conditions including hull shaking, tilting, heavy salt spray and high humidity. All units pass hydraulic pressure test, air tightness test and full-load linkage test before delivery, enabling automatic operation after simple pipeline and power connection onboard.

Core Product Advantages

1. Centralized High Cooling Capacity for Full-Ship Comprehensive Loads

Different from the single-point temperature limitation of individual marine air conditioners, the chiller provides continuous and stable large cooling capacity. It can simultaneously support the central air conditioning system of residential cabins and public areas, as well as the industrial cooling of instruments, hydraulic systems and process devices, solving the problems of insufficient refrigeration and large temperature fluctuation during simultaneous operation of multiple equipment.

2. Dedicated Seawater Heat Exchange System, No Cooling Attenuation in High-Temperature Seas

Adopting marine copper-nickel alloy heat exchange tubes, it resists seawater erosion, marine organism adhesion and chloride corrosion, adapting to seawater temperature conditions in global sea areas. Utilizing unlimited ship seawater for heat dissipation, it is not affected by high temperature, high humidity and stuffy sea conditions. Even under full load in equatorial high-temperature sea areas, the cooling capacity remains stable with no attenuation, delivering higher energy efficiency and stability than air-cooled equipment.

3. Full Marine-Grade Weather Resistance for Dynamic Vessel Working Conditions

Equipped with a heavy-duty composite shock-absorbing base, the unit withstands continuous hull vibration and bumping, and operates stably under ±30° hull tilt. The shell adopts enhanced anti-corrosion plates with multi-layer passivation treatment, and the electrical system is sealed for moisture and salt spray resistance, effectively avoiding common marine faults such as pipeline rusting, circuit dampness and loose parts, supporting long-term continuous ocean-going operation.

4. Intelligent Load Adaptation for Automatic Energy-Saving Operation

Equipped with Winnex Air exclusive intelligent control system, it real-timely monitors outlet water temperature, system pressure, pipeline flow and unit load, and automatically adjusts operating power according to cabin temperature demands and equipment loads to eliminate invalid energy consumption. It integrates start-stop delay protection, high/low pressure protection, overload/phase loss protection, insufficient water flow protection and fault self-check alarm, realizing unattended automatic operation and reducing manual maintenance costs.

5. Full Maritime Compliance for High-End Marine Projects

Designed, manufactured and inspected in strict accordance with CCS rules and SOLAS conventions, the electrical system meets marine EMC standards and can smoothly pass classification society inspections. Custom services including special marine voltages, customized cooling capacities and explosion-proof configurations are available to meet the needs of merchant ships, naval vessels and offshore platforms of different grades.

6. Integrated Turnkey Design for Easy Installation & Maintenance

The integrated modular unit is fully assembled before delivery, requiring no complex on-site assembly. It can be put into operation only by connecting seawater/fresh water pipelines and ship power. Core components are arranged on the front side with an open maintenance structure, enabling filter cleaning, component inspection and refrigerant detection without disassembling the whole unit, adapting to maintenance scenarios in narrow ship engine rooms.

Application Scenarios

Widely used in ocean-going container ships, bulk carriers, oil and chemical tankers, LNG vessels, research vessels, large yachts, offshore wind platforms, FPSO floating production platforms and offshore drilling platforms. It is mainly applied to ship-wide central refrigeration, cabin constant temperature adjustment, industrial equipment cooling, process system temperature reduction and special instrument constant temperature protection.

Full Lifecycle Services

Winnex Air provides one-stop full-lifecycle services: accurate marine cooling load calculation, unit selection, engine room layout design, pipeline system matching, manufacturing, onboard installation guidance, system commissioning, remote intelligent monitoring, annual maintenance and global after-sales support, delivering stable and reliable centralized refrigeration solutions for all kinds of marine projects.

Conclusion

As the core refrigeration hub of large vessels and offshore equipment, the stability, energy efficiency and weather resistance of marine water chillers directly determine the operating quality of ship HVAC and process systems. Featuring centralized high cooling capacity, high-efficiency seawater heat exchange, full-condition stable operation and intelligent energy-saving control, Winnex Air Marine Water Chiller perfectly adapts to complex ocean-going working conditions, making it the preferred core equipment for centralized refrigeration systems of medium and large vessels and offshore platforms.
