THM – AH Series – Air Oil Cooler
Extract destructive heat from your hydraulic systems and guarantee peak operational efficiency with the THM AH Series Air Oil Cooler. Engineered as a highly robust, energy-efficient thermal management solution, this series is designed to thrive in both stationary industrial plants and harsh mobile environments. By utilizing a premium aluminum fin-and-tube construction paired with high-performance axial fans, it rapidly dissipates heat directly into the ambient air, completely eliminating the threat of high-pressure fluid overheating. Available in highly customizable single or double-fan configurations and spanning a vast array of AC and DC operating voltages, the AH Series delivers the precise temperature regulation required to extend the lifespan of modern CNC machinery, marine hydraulics, and heavy earthmoving equipment.

Key Features & Engineering Advantages
- Dynamic Cooling Configurations: Tailor your thermal management to your exact heat generation levels. The series offers single or double dynamic axial flow fan setups (ranging from 250mm to 700mm in diameter) to ensure optimal heat dissipation speed.
- Robust Aluminum Construction: Manufactured from high-quality aluminum alloy and treated with a heavy-duty protective coating, making it highly resistant to the severe corrosion and abrasion found in marine and mining environments.
- Acoustic & Spatial Efficiency: The highly compact, lightweight design easily integrates into restricted spaces without requiring heavy structural framework. Furthermore, the noise-reducing fan motors operate at ≤ 75 dB(A), making them perfect for sound-sensitive indoor factory floors.
- Automated Safety & Efficiency: Can be equipped with built-in thermostatic control switches that automatically cycle the fans based on real-time oil temperatures, drastically reducing overall power consumption. An integrated bypass valve system safeguards the core from extreme pressure spikes during cold-weather startups.
- Versatile Installation: Designed for ultimate layout flexibility, allowing for horizontal, vertical, or even remote-mount installations using long-hose compatibility for the tightest machine compartments.
Ideal Industry Applications:-
The rugged versatility and broad voltage compatibility of the AH Series make it the premier cooling solution for:
- Industrial Manufacturing: Providing strict temperature control for 24/7 hydraulic presses, plastic injection molding machines, and high-speed CNC centers.
- Heavy Construction & Mining: Managing the relentless heat generated by heavy-duty continuous operations in bulldozers, loaders, and specialized mining/drilling rigs.
- Mobile & Agricultural Machinery: Regulating hydraulic fluid temperatures on excavators, backhoes, tractors, and harvesters during extended, sun-baked field operations.
- Marine & Renewable Energy: Maintaining the efficient operation of complex hydraulic machinery on offshore platforms, ships, and the pitch-control systems of wind turbines.
Installation & Maintenance Best Practices
- Installation: Ensure the cooler is mounted on stable ground (utilizing vibration isolators for mobile platforms) with unobstructed clearance for maximum airflow.
- Maintenance: The AH Series is designed for simplified servicing. Routinely cleaning the aluminum fins, inspecting electrical connections, and verifying thermal switch operation will ensure decades of reliable performance without requiring total system removal.
Why Choose the THM AH Series?
- Eliminate Unplanned Downtime: Protects your expensive hydraulic pumps and seals from thermal degradation, entirely preventing heat-induced system failures.
- Massive Energy Savings: Optional thermostatic controls and high-efficiency motors ensure you only pay for cooling power exactly when the machine needs it.
- Universal Adaptability: With flow rates from 10 to 300 L/min and virtually every standard industrial voltage available, the AH Series perfectly scales to your specific machine architecture.
