Cooling failure in hydraulic systems means automatic system shut down and unscheduled maintenance. The maintenance on cranes, ships and offshore wind turbines is extremely expensive to plan and the downtime costs money every minute. Therefore, it is important to have a supplier who can provide you with the correct technology to support your success.
Parker has developed a cooler with a protective coating and improved design features that will deliver high-performance cooling in erosive atmospheres. The MAC series cooler is not only more reliable but also longer lasting, thus improving the performance of your hydraulic system saving you time and money. Right now, the Parker MAC series cooler is the only cooler range available on the market offering this advanced level of protection. If you have a hydraulic system in a marine environment and want to increase your operation up time while reducing your maintenance, labor and spare part costs, then the Parker MAC series cooler is the ideal solution. The MAC series is engineered for both near-shore and offshore applications and provides cooling capacity up to 300kW. Corrosion resistance meets C4-M and C5M-M requirements in accordance with ISO 12944.
Following a number of customer interviews and feedback on our current marine product range, we realized the importance of developing a product which offers dependable performance throughout its entire life cycle. The corrosion resistance is not only about paint technology but is a combination of material selection, design features, and coating technology. Therefore the MAC series was engineered to allow customers to secure reliable performance at every stage of product usage. Products are delivered with safe and secure lifting points and with a clear installation manual in order ensure safe installation without damaging the coating. The round shaped interface avoids friction and allows perfect coating adhesion thus reducing the risk of damaging the coating when the cooler is installed. Cabling of the electrical motor is often done on site and this is why the electric box is also coated internally to avoid rust inside the following installation.
During operation, the product can be exposed to erosive atmospheres. The electrical motor has tropicalized coating to avoid corrosion inside the housing. Coating technology used for metallic parts was qualified on test pieces representative of the metal sheet design. This was developed to allow the assembly and removal of the fasteners (at the recommended torque) without damaging the coating. The coating itself was tested for up to 1440 hours in neutral salt spray test according to ISO 9227 standard and achieved the following results:
- Degree of rusting Ri 0 (no rusting) according to ISO 4628-3:2003 standard
- Degree of blistering 0 (S0) (no blistering) according to ISO 4628-2:2016 standard
- Degree of cracking 0 (S0) (no cracking) according to ISO 4628-4:2016 standard
- Degree of flaking 0 (S0) (no flacking) according to ISO 4628-6 standard
- Spread from scribed line (infiltration) =1 mm according to ISO 12944-6 standard.
