Steel Cooler
Bundled to perfection
Steel coolers are efficient cooling systems designed for installation in several maritime, stationary and industrial applications. Steel coolers cooling the primary circuit using open water. A closed-circuit cooling system, which do not need any water-filters, valves, inboard heat exchanger, raw water pumps, seawater piping and strainers. The Steel coolers can be mounted externally as well as internally into the ship’s hull.




Technology
Engineered to cool
A Steel cooler is a closed-circuit cooling system mounted internally within the sea chest of the vessel or externally on the vessel’s hull below the waterline. The concept of steel cooling is similar to the application of a radiator on a car. Engine coolant is circulated through the steel cooler, which transfers heat from the coolant to the seawater before it returns to the engine. The steel cooler is in constant contact with (sea)water allowing the cooling system to efficiently transfer heat between the coolant and (sea)water.
ADVANTAGES
Compared to an open circuit cooling system (inboard heat exchanger), a closed-circuit cooling system provides several distinct advantages. A closed-circuit cooling system eliminates the need for an inboard heat exchanger, raw water pumps, strainers, seawater piping, and the high maintenance associated with open circuit cooling systems. It also eliminates silt and sand build-up in the cooling circuit and protects the system from saltwater corrosion.

Materials
The Selection of possible materials
The Weka Steel Cooler is a completely assembled unit and is factory tested to ensure dependability. Depending on your application and situation the Weka sales and engineering team will assist you in selecting your material for your situation.

Steel Coated
In some situations, a treatment of steel coolers with phenol heat-cured coatings is necessary. This is important for the protection against galvanic corrosion and combines this with high heat-conductivity properties.

Steel Galvanised
Galvanized steel cooler is built with regular steel tubes that have been coated in zinc to make them corrosion resistant. Regular steel is made of iron which will rust when exposed to (sea)water. Over time rust will corrode a steel part to the point of failure. To prevent this from happening Weka will provide a custom-made steel galvanized cooler.
Steel Cooler Advantages
Strong & Solid

For the most difficult circumstances
Each steel cooler will be designed and built according the heat source its requirements and operating environment. Steel coolers are more resistant to external forces and are strong and solid. Because of its design characteristics, the weka steel cooler can be used in various applications and has several installation options. For example; stationary or industrial application, internally (sea chest) installed, externally installed (bottom or side mounted onto the ship’s hull) and inland water applications.
Our expert engineers and sales team will help you determine the best installation solution. Please note the operating conditions and hull design of a vessel weigh heavily on how a unit is installed.
