Koja EQUIPMENT DELIVERY

EQUIPMENT DELIVERY

Koja’s innovative equipment features highly compact sizes and structures, allowing for efficient space utilization. This reclaimed space can be utilized for added value, such as additional cabins.

Equipment deliveries include ship-specific air handling units and fan coil units. Our products are manufactured in-house at Koja’s production facilities in Finland. The Finnish origin of our products is recognized by the Key Flag symbol, awarded by the Association for Finnish Work.

The new Marine Future® S concept provides significant savings opportunities over the entire life cycle of a vessel. With optimized energy efficiency, it is possible to achieve savings of up to hundreds of millions of euros. The compact design and dimensions allow for space savings that enable the construction of additional cabins, generating tens of millions of euros in additional revenue during the life cycle of large cruise ships.

Koja Marine AUTOMAATIO

AUTOMATION

Koja’s extensive expertise in electrification and automation ensures that onboard conditions remain optimal in both cabins and public areas—day and night, all year round. Our automation solutions are meticulously tailored to each vessel and undergo comprehensive factory testing before delivery.

Automation products include HVAC automation systems, cabin automation systems, and occupancy-based ventilation (OBV®).

Koja marine ENERGY EFFICIENCY CONCEPTS

ENERGY EFFICIENCY CONCEPTS

Optimizing air handling efficiency can have a profound impact on a ship’s overall energy performance.

The CO2-based recirculation function in air handling units efficiently recycles air, improving the vessel's energy efficiency and reducing operating costs.

The Occupancy-Based Ventilation (OBV) enables substantial energy savings, reducing the energy consumption of cabin ventilation by up to 55% compared to conventional systems.

The air recirculation function in air handling units enhances energy efficiency by recycling air through the unit. This feature leverages indoor air temperature and humidity properties while reducing the energy demand of fans.
