Active Refrigeration provides marine engineering solutions for Deep Water Fleet (DWF) trawlers, installing and maintaining large-scale ammonia refrigeration systems that enable onboard processing and blast-freezing. These vessels function as floating factories, allowing seafood to be processed at sea and exported directly from port.

Effective humidity management systems are crucial to preserving the texture and flavour of fish by preventing moisture loss. Designing refrigeration units with separate compartments and proper airflow management helps prevent cross-contamination, ensuring different types of seafood are stored safely. Active Refrigeration can deploy thermal energy storage and predictive control models to optimise compressor operations and reduce energy consumption.

Partnering with New Zealand’s largest fishing companies, including Sanford and Sealord, Active Refrigeration delivers specialised refrigeration solutions that are essential for maintaining product quality, meeting strict industry regulations, and ensuring an efficient seafood supply chain.

Active Refrigeration has supplied energy-efficient refrigeration technologies, such as CO2-NH3 cascade systems, to reduce operational costs and support sustainability goals. Integrating smart refrigeration systems with sensors and IoT capabilities allows for real-time monitoring and control, enabling proactive maintenance and reducing downtime.

Beyond seafood production, Active Refrigeration provides specialised marine cooling solutions for freighters and cargo ships to ensure reliable climate control in demanding offshore environments. Air conditioning systems are designed to enhance crew comfort, regulate onboard temperatures, and maintain safe working conditions, even in extreme climates. With expertise in marine-grade refrigeration and HVAC systems, Active Refrigeration delivers efficient, reliable solutions built for the demands of the maritime industry.
