MARENUM chillers: customised technology for ships
On ships, maximum efficiency must be guaranteed in the smallest of spaces. Our team of experts has developed the seawater-resistant MARENUM chillers precisely for these conditions. Every centimetre counts here, as does a stable and reliable supply and maximum cooling capacity. A customised technology solution for shipping!
Get to know MARENUM better
Developed for demanding use on ships: MARENUM. The compact chillers impress with the best material quality and high cooling capacity in a small space. The seawater-resistant models are available from a cooling capacity of 300 kilowatts.
As not all ships are the same, MARENUM is available in two versions specially tailored to the respective area of application:
- MARENUM CIVIL: as technology in civil shipping, such as on ferries, freighters and yachts
- MARENUM NON CIVIL: for use in non-civilian shipping, such as on frigates and patrol vessels
We will be happy to discuss the optimum solution for your particular application with you!
Despite its compactness in the smallest of spaces, you don't have to do without superior technology. MARENUM has special technical features that are precisely tailored to use on the high seas:
- Maximum efficiency: Compact design for high cooling capacity in a small space
- Powerful at the core: turbocompressor for a mains frequency of 50 or 60 Hz
- No distraction: Smooth starting behaviour, low noise and vibration
- Smart control: No reactive current compensation, infinitely variable power control
- Looking to the future: The latest filter technology for ships and innovative MSR design
- Ideal performance: Power supply of 400 V/50 Hz or 440 V/60 Hz without transformer
Stainless steels that can withstand the demanding seawater conditions are just one of MARENUM's specialities. Because refrigeration technology on ships has to withstand a lot.
An alloy of copper, nickel and iron for tube sheets and high-performance finned tubes for seawater-cooled condensers also ensure that the seawater-resistant chillers work perfectly and with maximum efficiency at all times.
There is no room for error on the high seas. That's why MARENUM is optimised for use in seawater conditions and meets the highest safety standards. With our refrigeration technology for ships, you benefit from safe performance combined with maximum energy efficiency.
High-performance finned tubes for seawater resistance and a controllable three-way valve are used in the chillers, which together enable trouble-free operation at seawater temperatures of -2 to+ 36 degrees Celsius. A redundant design with several compressors ensures reliability.
A comprehensive, international service network guarantees you fast and competent support. Because with us as a partner at your side, you are never alone.
In summary: What are MARENUM chillers from ENGIE Refrigeration?
MARENUM chillers from ENGIE Refrigeration are specifically designed for use on ships and in offshore applications. They reliably provide cooling in maritime environments. For example, for air conditioning or process cooling on board cruise ships, naval vessels, utility ships, or offshore platforms.
MARENUM chillers are seawater-cooled and designed to meet the specific demands of maritime environments: compact design, high operational reliability, corrosion resistance, and stable performance even under fluctuating operating conditions. Thanks to robust components and a marine-grade design, they meet maritime standards and classification requirements.
A major advantage of the MARENUM series is its high energy efficiency combined with a small footprint—a crucial factor on ships. The systems operate reliably in continuous service and help reduce energy consumption and operating costs.
With the MARENUM chillers, ENGIE Refrigeration offers a durable, efficient, and customized refrigeration solution for the maritime industry, including engineering expertise, service, and many years of experience in the marine sector.
