DH-194-1-1 Oil Cooler
Thermal Transfer DH-194-1-1 coolers are designed for mid-range hydraulic systems, handling 2–15 GPM with the ability to pass up to 150 GPM flow. They operate at up to 300 PSI and feature a compact 1.15 face area with a 3/4″ NPT port size, enabling straightforward integration into standard setups with limited space. Suitable for applications requiring reliable cooling without heavy-duty fan assistance.
DH-249-1-1 Oil Cooler
DH-249-1-1 extends the performance envelope for higher-demand lines, supporting 4–38 GPM with oil flows up to 150 GPM. Rated at 300 PSI, it features a larger 2.47 facing area and a 3/4″ NPT port, making it suitable for heavier machinery while maintaining compact footprint and straightforward mounting options.
MA Series Without Fan MA-4-2
MA-4-2 is a fanless oil cooler designed for space-constrained environments where passive cooling suffices. It handles up to 20 GPM with flows up to 125 GPM and operates at 250 PSI. With SAE #16 port sizing, this unit is a practical match for smaller hydraulic circuits seeking reliability without added active cooling components.
M Series M-20
M-20 provides a versatile mid-range cooling solution with 4–40 GPM capability and up to 100 GPM flow, while maintaining 300 PSI and a 1″ NPT port. Its 14.88 L x 19.72 W footprint suits varied hydraulic installations, delivering robust heat rejection suitable for general-purpose industrial cooling.
MF Series MF-15-1-4A
MF-15-1-4A integrates a 12V DC fan, providing active cooling for higher loads up to 55 GPM and up to 175 GPM peak flows. It features heavy-duty aluminum fins and 3/8″ tubes with 1″ NPT options, designed for industrial, agricultural, and construction environments where steady, energy-efficient cooling is essential.
Buying Guide: Key Purchase Considerations
- Flow rate and load criteria: Choose a cooler that matches your system’s steady-state GPM and peak surge conditions. Models in this guide range from light to heavy duty, with some offering passive cooling and others with fan-assisted operation.
- Pressure rating: Ensure the PSI rating aligns with your hydraulic circuit pressure. All featured units list 250–300 PSI, suitable for most industrial fluids under typical operating ranges.
- Port sizing and connections: Verify that port dimensions (NPT sizes and SAE ports) align with your hoses and fittings. Incompatibility can require adapters or reducer fittings.
- Cooling medium compatibility: Confirm the cooler material and fin design are suitable for the oil type used in your system (e.g., mineral vs. synthetic) to prevent corrosion or fouling.
- Noise and energy considerations: Fanless models provide quieter operation and lower energy use, but may require more space and rely on ambient cooling efficiency. Fan-assisted units deliver higher cooling capacity in demanding environments.
- Footprint and mounting: Check dimensions and mounting kit availability. Some units include multiple mounting configurations to fit tight spaces or complex machinery assemblies.
- Maintenance and serviceability: Look for units with accessible fins and straightforward filter or cleaning paths. Durable construction with aluminum fins supports longer service life in harsh settings.
- Warranty and support: Favor brands with solid warranties and readily available technical support to reduce downtime in critical operations.
- Vendor ecosystem: When selecting from a single brand family, consider compatibility across product lines to simplify future upgrades or replacements.
- Operating environment: Consider exposure to dust, vibration, and temperature extremes. Heavier-duty models tend to fare better in demanding environments.
For optimal results, match the cooler’s specifications to the hydraulic circuit’s actual operating profile. A well-selected unit minimizes oil temperature rise, reduces wear, and supports consistent performance across production cycles.
