We from Weka Marine have experience in serving the marine industry since 1957. During this period we have heard a lot of questions, some of these questions come by regularly and therefore we have summarized and answered them below:
- I have little space, can I use a Weka Boxcooler?
- To save space, we have developed a so-called “Stepping Unit”. This application allows us to supply the required cooling capacity with less space.
- Do I need an Icaf system or coating for a Weka boxcooler?
- No, Weka Boxcoolers are constructed using uncoated 90/10 copper-nickel tubing. This alloy does not require a protective coating or ICAF (Impressed Current Anti-Fouling) system due to its inherent corrosion resistance to seawater and natural anti-fouling capabilities.
- What information do you need to engineer a product?
- Our team will need the following specifications to make a proper product recommendation:
- Engine Type (Propulsion, Bow Thruster, Generator, Other)
- Emissions Data (Tier 1, 2, 3, or IMO)
- Engine Manufacturer
- Rating (BHP / RPM, BKW / RPM, EKW / RPM)
- Engine Age
- Percentage of Antifreeze Used
- Heat Rejection
- Fresh Water Flow Rate
- Fresh Water Temp Into Cooler
- Fresh Water Temp Out or Drop Across Cooler
Reduction Gear Information
- Make and Model of Gear
- Type of Vessel (e.g., Ferry, Trawler, Tug)
- Hull Construction (Steel, Fiberglass, Wood, Aluminum Painted/Unpainted)
- Minimum Hull Speed at Full Rated Power (Under Full Load)
- Maximum Seawater Temp
- What does the maintenance of a boxcooler look like?
- Once every 5 years when the ship is brought ashore for maintenance, the box cooler, if it has been grown, must be cleaned with high pressure water jets.
