Marinised Coolers

A marinised cooler is a hydraulic heat exchanger that has been specially treated or constructed to resist corrosion in marine environments. These coolers regulate hydraulic oil temperature by transferring heat to air or water, preventing overheating and maintaining optimal system performance.

Typical features include:

• Anti-corrosion coatings or stainless steel construction

• Sealed housings and marine-grade fittings

• Compact, vibration-resistant designs

• Air-oil or water-oil cooling configurations

Hydraulic systems generate heat during operation, and in marine or offshore settings, that heat must be managed without compromising durability. Marinised coolers offer:

• Corrosion resistance – protects against saltwater, humidity, and chemical exposure

• Efficient heat dissipation – maintains oil temperature within safe operating limits

• Extended component life – reduces wear and risk of thermal damage

• Compact integration – fits into confined spaces on vessels and platforms

• Low maintenance – designed for long-term reliability in remote or hard-to-access locations

These benefits are critical for maintaining uptime and safety in mission-critical marine operations.

Marinised hydraulic coolers are used across a wide range of sectors, including:

• Offshore drilling and production

• Shipboard hydraulic systems

• Subsea equipment

• Port and dockside machinery

• Renewable energy platforms

Whether you need a standard unit or a custom-engineered solution, our team can help design and deliver a cooler that meets your exact specifications.

We source marinised coolers from a wide network of manufacturers, including:

Emmegi, Olaer, Parker… and many more

As an independent supplier, we offer unbiased recommendations based on your system’s needs – not a manufacturer’s catalogue.

What’s the difference between a standard and marinised cooler? Marinised coolers are built or treated to resist corrosion, making them suitable for saltwater and offshore environments.

Can marinised coolers be custom-sized? Yes, we offer both standard and custom solutions tailored to your flow rate, temperature range, and installation constraints.

How do I know what size cooler I need? Our technical team can help you calculate the correct size based on your system’s heat load, operating conditions, and ambient environment. You can also refer to our cooler sizing guide for more insights.
