The Thermal Transfer Products Mobile M Series is a heavy-duty, copper-tube/aluminum-fin cooler core built for mobile and off-highway equipment — one of the most rugged and robust heat exchangers in the TTP family. As a core without its own fan, it’s designed to face-mount to a radiator or integrate within an engine cooling module, using existing engine airflow to cool the fluid. That makes it a compact, cost-effective way to add oil, fuel, or transmission cooling to a mobile machine.
The design delivers high flow capacity and high heat removal, and its high/low turbulators optimize heat rejection even at lower flow rates. An optional internal pressure bypass protects the hydraulic system during cold starts and pressure spikes, and because it’s internal, it reduces plumbing complexity by eliminating external piping. Rugged off-highway steel-fin and steel-manifold configurations are available for high-vibration, dusty, or corrosive environments.
Common applications include hydraulic oil, fuel, and transmission cooling in mobile systems. The M Series carries a maximum operating pressure of 250 PSI and a maximum operating temperature of 350°F, with oil flows up to roughly 150 GPM and heat removal to about 175,000 BTU/hr across the model range. TTP’s XSelector® sizing program and 3D configurator help select and build the right core for your system.
The Thermal Transfer Products Mobile DF Series is a rugged air-cooled hydraulic oil cooler engineered for very demanding mobile and off-highway applications. Its robust design features steel tanks and damage-resistant steel fins — rather than the more delicate aluminum fins used on lighter-duty coolers — so it withstands impact, flying debris, vibration, and rough handling in the field while delivering moderate flow rates and high heat removal.
The DF is driven by 12- or 24-volt DC fans or a long-life hydraulic fan motor, letting you match the drive to the power available on the machine. An optional serviceable internal pressure bypass provides cold-start protection and can be removed for service without disturbing the plumbing. It’s well suited to construction, agriculture, forestry, mining, and material-handling equipment that runs in dirty, high-vibration conditions.
The series has a maximum operating pressure of 300 PSI and a maximum operating temperature of 350°F. It shares its performance profile with the DH Series, but where the DH is a lighter radiator-face-mount and low-flow solution, the DF adds its own DC or hydraulic fan drive and heavier steel construction. TTP’s XSelector® sizing program — available online and as a mobile app — helps size the right model for your flow, heat load, and mounting.
The Thermal Transfer Products Mobile MF Series is a self-contained, air-cooled hydraulic oil cooler for mobile equipment — the rugged M Series core with an integral fan drive added, so it doesn’t depend on radiator or engine airflow. You can specify a low-amp-draw DC motor or a long-life hydraulic fan motor to match the power available on the machine.
Its robust, off-highway-grade construction uses a steel manifold, copper tubes, and aluminum fins, and high/low turbulators optimize heat rejection even at lower flow rates. An optional serviceable internal pressure bypass provides cold-start protection and can be removed for service without disturbing the plumbing. The MF is well suited to higher-pressure mobile hydraulic applications where a dedicated fan is needed rather than relying on engine airflow.
Common applications include hydraulic oil, fuel, and transmission cooling on construction, agriculture, forestry, and material-handling equipment. TTP’s XSelector® sizing program — available online and as a mobile app — helps size the right MF model for your flow, heat load, and available power.
