Rugged Mobile Air-Cooled Oil Cooler — Steel Tanks & Damage-Resistant Steel Fins
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.

Frequently Asked Questions
It’s a rugged air-cooled hydraulic oil cooler from Thermal Transfer Products, built with steel tanks and damage-resistant steel fins for very demanding mobile and off-highway equipment.
Steel tanks and steel fins instead of aluminum fins, so it resists impact, debris, and vibration damage in harsh field conditions — where a standard aluminum-fin cooler would dent or clog.
12- or 24-volt DC fans or a long-life hydraulic fan motor drive, chosen based on the power available on the machine.
They have a similar performance profile, but the DH is a lighter-duty, radiator-face-mount / low-flow cooler, while the DF adds heavier steel construction and its own DC or hydraulic fan drive for tougher, more independent-cooling duty.
Maximum operating pressure is 300 PSI and maximum operating temperature is 350°F.
Construction, agriculture, forestry, mining, and material-handling equipment — mobile machinery that operates in dirty, high-vibration, impact-prone environments.
