In the southern coastal region, where the seafood processing industry keeps running almost 24 hours a day, maintaining the right refrigeration temperature is absolutely crucial. Recently, HACST Cooling completed a customized project of four evaporative condensers for a client operating fish processing plants in both Australia and New Zealand. Each condenser was specially designed to meet local operation conditions and energy standards, ensuring stable performance even under high humidity and salty air environments.
The evaporative condenser is one of the most efficient industrial heat exchange systems today, combining the principles of evaporation and heat transfer to reduce refrigeration load. For seafood factories, which require continuous cold storage and quick-freezing at -25°C or below, the energy efficiency and reliability of the condenser can directly affect product quality and production cost.
Unlike standard models, the four units supplied this time were customized in size and coil configuration based on the client’s layout plan. The processing line included both automatic cleaning areas and blast-freezing chambers, requiring flexible installation spaces. HACST’s engineering team redesigned the framework and fan section to make the equipment more compact while keeping high heat transfer efficiency.
All components were manufactured in the HACST factory with galvanized steel casing and copper coil with corrosion-resistant coating. Considering the coastal climate in Australia and New Zealand, where salty wind and humidity can shorten equipment lifespan, special protection layers were added to ensure long-term operation stability. The fan blades adopted an aerodynamic design, reducing power consumption and noise — an important factor for plants located near residential or port areas.
For transportation, the four condensers were loaded into frame containers to guarantee safety and easy unloading at the port. Frame-type packaging not only reduced shipping cost but also minimized the risk of damage during sea transport. Upon arrival, the customer’s technical team conducted an on-site inspection and praised the overall build quality and precision of the unit assembly.
In modern industrial refrigeration systems, the evaporative condenser plays a key role in energy optimization. Compared with traditional air-cooled or water-cooled systems, it uses the evaporation of water to achieve greater cooling efficiency. This reduces the compressor load by up to 20%, saving energy while maintaining a more consistent condensing temperature.
According to the feedback received two months after commissioning, the system has been running smoothly with stable pressure and temperature control. The client reported that the average daily power consumption of the refrigeration unit dropped by nearly 15% compared to the previous system. This improvement not only saves energy cost but also contributes to the sustainability goals that many seafood companies in Australia and New Zealand are focusing on.
From a long-term perspective, projects like this demonstrate HACST’s technical strength in customized evaporative cooling solutions. Every country, every industry, every climate — they all have their own challenges. But with professional design and careful production, a condenser can adapt perfectly to each condition. Whether it’s seafood processing, cold storage, beverage manufacturing, or chemical production, the same engineering philosophy applies: energy efficiency, reliability, and easy maintenance.
