Censeanku AH1490T-CA DC24V Oil Cooler
Specifications highlight a high-flow design with 250 L/min capacity and a 2 MPa working pressure. Cooling capacity reaches 24,000 Kcal/h, and the unit features a large 350 mm fan and RC1-1/4″ connections for reliable sealing in vibration-prone environments. Best for heavy machinery where rapid oil temperature reduction is essential, such as excavators and large injection-molding equipment. A potential limitation is its size and power draw, which may require a robust electrical and mounting setup.
AH1417T-CA Hydraulic Oil Cooler
This 12V, 120W fan cooler delivers steady heat dissipation with a 10,000 Kcal/h capacity and a flow rate of 150 L/min. It’s constructed from premium aluminum alloy for corrosion resistance and durability in harsh environments. Best for mid-size hydraulic systems that require reliable cooling without excessive power use. Limitation: lower cooling capacity than high-flow models, so it’s best suited for moderate workloads.
ArbDicco AH1470T-CA Hydraulic Oil Cooler
With DC12V operation and a 200 L/min flow, this cooler provides up to 18,000 Kcal/h cooling capacity. The unit uses a 350 mm fan and RC1-1/4″ threading for solid connections, making it suitable for medium-to-large hydraulic systems that need consistent cooling without high electrical demands. Best for users who want a robust option with strong airflow. Caution: longer-term vibration exposure should be monitored to avoid mounting wear.
AH1012T-CA Air Cooled Oil Radiator
Features a 12V DC, 120W fan with 100 L/min flow and 6,000 Kcal/h cooling capacity. The unit’s 3.2㎡ exterior cooling area and RC1″ connection offer precise control for a broad range of hydraulic systems. Best for compact installations requiring reliable, lower-capacity cooling. Limitation: may not meet the needs of high-throughput systems or very hot environments.
AH0608T-CA Hydraulic Oil Cooler
Designed for 1-2 ton mini excavators, this 60 L/min, 12V cooler keeps working pressure up to 2 MPa and uses a 6.7-inch fan. Exterior area is 1.3㎡, with 9,120 BTU/hr (2,300 Kcal/h) cooling capacity. Best for OEM replacement needs in small machinery. Limitation: lower flow and cooling capacity compared to larger, higher-flow models.
Buying Guide: Key Considerations For Choosing An Auxiliary Hydraulic Oil Cooler
- System compatibility: Confirm voltage (DC12V vs DC24V) and thread type (RC1-1/4″ or RC1″), ensuring a proper fit with your equipment’s connectors and power supply.
- Flow rate vs. cooling needs: Higher flow (L/min) generally supports larger systems or higher heat loads. Match the candidate’s capacity to your device’s oil consumption and ambient conditions.
- Cooling capacity: Measured in Kcal/h or BTU/h. Consider environments with sustained operation and high-temperature exposure; pick a unit that maintains oil temperature within safe limits.
- Durability and mounting: Look for leak-proof interfaces, vibration-resistant housings, and robust materials for harsh environments like construction or mining sites.
- Size and weight: Ensure space allows installation and does not overburden mounting points or frame structures.
- Noise and power: Larger fans can generate more noise and draw more power. Balance cooling performance with noise tolerance and electrical capacity.
- Maintenance access: Choose units with accessible filters or easy-to-service components to minimize downtime.
Frequently Asked Questions
- What is an auxiliary hydraulic oil cooler used for? It provides additional cooling for hydraulic systems, preventing overheating and maintaining efficiency in demanding operations.
- Why choose a higher flow model? Higher flow helps remove heat quickly in high-load scenarios or when oil temperature rises rapidly under load.
- What voltage should I look for? Match the cooler’s voltage to your machine’s electrical system (commonly 12V or 24V).
- Are these compatible with all hydraulic systems? These options are designed for common engine-driven or electric-powered systems; verify thread size and pressure ratings before purchase.
- How important is the cooling area? A larger cooling area improves heat transfer and can sustain performance longer in hot environments.
- Do these require professional installation? Installation can be straightforward for standard bolt-on mounting, but consider a technician for complex assemblies or high-pressure lines.
