With our advanced technology, innovative systems, and services, we help our customers achieve their sustainability goals. Koja's intelligent HVAC solutions are the soul of the ship.

Reliability of delivery, exceptional quality, and efficiency make Koja the top choice for the world’s leading shipping companies. Continuous product development and unparalleled electrical automation reduce life cycle costs and environmental impact.

IN-HOUSE R&D, PRODUCTION, DESIGN AND SERVICES SUPPORT THE VESSEL’S LIFE CYCLE

Koja’s unique operating model ensures quality and efficiency at every stage. Our operations cover the entire chain from concept to commissioning with our own resources—seamlessly. When the entire life cycle of the HVAC system is individually dimensioned and optimized from the design stage, the benefits are multiplied. Structures and components are rigorously tested in extreme conditions, and ultra-modern production lines shorten manufacturing lead times. Koja supports, consults, and serves at every stage of the life cycle.
