Marine AHU Core Features

Multi-source heating and cooling configuration, energy-efficient

Supports chilled water (central chilled water), direct expansion (DX with built-in compressor) and heat recovery functions, utilizing waste heat from the main engine cylinder liner for energy-saving heating. Flexible selection of heating and cooling sources adapts to different ship energy configurations.

Designed specifically for marine environments, vibration-resistant and corrosion-resistant

Vibration-resistant and anti-sway design (vibration-damping base + flexible connection) adapts to vibration, roll, and pitch conditions during ship navigation; marine-grade anti-corrosion coating, salt spray test ≥1000 hours; key components are made of 316L stainless steel, offering excellent corrosion resistance. Superior Precision Control, Comfort and Energy Saving: The microcomputer controller supports Modbus/RS485 communication and can be connected to the Integrated Ship Management System (IAS); temperature control accuracy is ±0.5℃, humidity control accuracy is ±5%, achieving precise adjustment of the cabin environment; optional EC fans, saving more than 30% in energy.

Compact Structure and Convenient Maintenance

Modular design, compact size, and multiple installation methods including horizontal, vertical, and ceiling-mounted, adapting to the confined space of the ship's cabin; easy-to-clean filter + access door design + self-diagnosis of faults, simplifying maintenance and reducing downtime.

Application Scenarios

Ocean-going Merchant Ships: Crew living quarters, restaurants, and entertainment areas on cargo ships, container ships, and oil tankers.
Passenger Ships and Yachts: Passenger cabins and public areas on luxury yachts, ferries, and cruise ships.
Offshore Platforms: Living quarters and control rooms on drilling platforms and oil production platforms.
Engineering Vessels: Crew cabins on tugboats, dredgers, and pipelaying vessels.
Warships: Air conditioning systems for cabins on warships and supply ships.
