Bearing oil coolers built for reliability
Bearing oil coolers engineered to protect bearings and stabilise oil temperature. Exact fit solutions built for demanding operation.
Proven
Bearing oil coolers designed for serious work
GWA ring oil coolers manage the heat that standard equipment cannot handle. Built from proven designs and tested across thousands of operating hours, they keep your machinery cool when it matters most.

Quality & Testing
What makes our bearing oil coolers work reliably
A bearing oil cooler does one job and does it well—it removes heat before it becomes a problem. GWA coolers are built on simple principles executed with precision, keeping oil at the right temperature so your machinery stays reliable.
I
Thermal and hydraulic design
Project specific design based on operating parameters such as heat to be dissipated, water flow rate, inlet and outlet temperatures, and allowable pressure drop. The objective is stable cooling performance with safe flow velocities and long service life.
II
Material selection
Selection of suitable materials for tubes, tubesheets and headers based on operating conditions and water quality parameters.
III
Pressure and leak testing
Hydrostatic pressure testing to verify mechanical strength and tightness of the cooler. Particular focus is placed on tubesheets, headers, welds and all pressure retaining components.
IV
Quality control and documentation
Dimensional inspection, verification of manufacturing quality, and preparation of technical documentation such as drawings, material certificates and test reports. Additional inspections or ITP requirements can be implemented if requested.
V
Final inspection and delivery
Final inspection prior to shipment. Customer inspection or third party inspection can be arranged if required.
Precision
Premium Material Integrity
GWA selects materials specifically for their superior thermal properties and environmental resistance, ensuring long-term durability in the most punishing climates.
Real-World Pressure Testing
Every cooler undergoes rigorous testing that mirrors actual operating conditions. This guarantees structural integrity where equipment faces its hardest demands.
Engine-Specific Customization
Move beyond standard solutions with designs precision-engineered for your specific engine needs, ensuring perfect integration and optimal cooling performance.
