DC Fan-Driven Air-Blast Coolers

Compact Cooling for Mobile Hydraulic Systems

DC fan driven air blast coolers are designed to regulate hydraulic oil temperature in mobile and off-grid systems. By using a direct current (DC) powered fan to force ambient air across a radiant surface, these air-oil heat exchangers offer efficient, self-contained cooling without the need for external power sources or water circuits.

At Hydraulics Online, we supply DC fan driven air blast coolers from a wide range of global manufacturers – including Emmegi – with expert advice to help you select the right solution for your application.

A DC fan driven air blast cooler uses a fan powered by a DC motor to draw ambient air across a heat exchanger core. As hydraulic oil flows through the cooler, heat is transferred from the oil to the air, lowering the fluid temperature before it returns to the system.

These coolers are ideal for:

Mobile hydraulic equipment
Off-highway and agricultural machinery
Remote or battery-powered systems
Marine and offshore installations

Self-contained cooling – operates independently of AC power or external cooling circuits
Compact and lightweight – perfect for mobile and space-constrained applications
Energy-efficient – low power draw with effective heat dissipation
Durable construction – built for rugged environments and continuous use
Flexible mounting options – suitable for vertical or horizontal installation

These features make DC fan driven air blast coolers a trusted solution for systems where portability, reliability, and thermal control are essential.

Can these coolers run off vehicle batteries? Yes, DC fan-driven coolers are designed to operate on 12V or 24V systems, making them ideal for mobile equipment.

Are DC coolers suitable for continuous operation? Absolutely. Many models are built for heavy-duty use and offer long service life under demanding conditions.

Do DC coolers require external control systems? Some models include integrated thermostatic switches, while others can be paired with external sensors or controllers.
