Each solution is engineered to meet the requirements of your engine, vessel, and operating conditions. Next to our cooling solutions, Weka also offers a wide range of other marine products, such as a serie of tank gauging equipment, Weka Water Jet, and ultrasonic anti-fouling system, environmental biological fouling protection device and Boxcoolers protection system.

Integrated & tailored solutions
Your partner in shipbuilding and operations
We understand the shipyards building process and the end user’s operation. Weka provides cooling solutions and other marine products by engineering and integrating tailored solutions in order to achieve optimal product performance while maintaining the right integral cost price. Our ‘first time right’ project approach is valued by our partners because our excellent technical coordination during the engineering, production or commissioning processes, relieves the shipyard during their building process.
We’re on a mission
Maximize your cooling capacity & support marine life
Our Weka Marine Environment (WME) program, enables you to move towards a resilient ocean (sustaining marine life and functioning ecosystems) and an efficient cooling system on board.
How? Through our circular economy process and innovative cooling products that deliver sustainable productivity and meet your challenges, such as rising operation costs, tighter regulations and increased societal expectations. WME Program is feasible today, requiring a small shift in how we collaborate and innovate. WME Program is an invitation to join us in co-creating and adopting the solutions that will transform maritime industry into more sustainable industries and taking care of our oceans in the process.
