Selecting the correct cooler depends on several key parameters: total heat load (in kW), oil flow rate (L/min), maximum working pressure (bar), and the ambient temperature of your operating environment. At MEISON, we provide a cooling capacity selection tool. Please share your system’s heat dissipation requirements and hydraulic fluid type, and our engineers will calculate the optimal model from our AH, AD, or AW series.
What is the maximum operating pressure of MEISON oil coolers?
Our standard aluminum air-cooled oil coolers are designed to withstand high working pressures, typically up to 26 bar for heavy-duty applications. For specific requirements regarding peak pressure or high-viscosity oil, please consult our product brochure or contact our technical team for custom reinforcement options.
Yes. We specialize in both standard production and custom OEM/ODM solutions. Whether you require specific branding, custom dimensions for limited machine spaces, or specialized fan configurations, our factory-direct expertise ensures a seamless development cycle.
What are your requirements for MOQ (Minimum Order Quantity)?
We support flexible ordering to accommodate both B2B wholesale partners and specific project-based requirements (like Project URSA). For standard items, we offer lower MOQs to help you manage inventory costs. For custom-engineered solutions, MOQs are determined based on tooling and production complexity. Please reach out for a tailored quote.
Are MEISON products CE certified for the European market?
Absolutely. We prioritize international standards. Our cooling systems are manufactured under strict ISO9001 quality management systems and hold the necessary CE certifications required for export to the EU, including Poland and Germany. We ensure all electrical components are compatible with 400V-3N-50Hz power standards.
What is the expected service lifespan of your air-cooled oil coolers?
Designed for industrial durability, MEISON coolers are engineered for a service life of up to 10+ years under proper operating conditions. We utilize high-efficiency aluminum alloy construction that balances thermal performance with corrosion resistance.
How often should I clean my air-cooled oil cooler?
Maintenance frequency depends on your work environment. In dusty industrial settings, we recommend periodic inspection of the cooling fins. If you notice a decrease in cooling efficiency, use low-pressure compressed air or a soft brush to remove dust and debris. Avoid using high-pressure water sprays that could deform the cooling fins.
What should I do if I notice an oil leak at the connection point?
First, immediately depressurize the system and allow it to cool. Check if the sealing O-rings are worn or if the torque is insufficient. If the leak persists, or if there is physical damage to the core, please contact our support team. We provide a comprehensive spare parts list to ensure your equipment is back in operation as quickly as possible.
What is the working principle of a hydraulic oil cooler?
The working principle is based on forced convection heat transfer. Hot hydraulic oil circulates through internal aluminum tubes (fins), while a high-powered fan blows ambient air across the external fins. This process effectively removes excess heat, ensuring the oil maintains its viscosity and protecting hydraulic components from premature wear.
Why should I choose an air-cooled heat exchanger over a water-cooled one?
Air-cooled heat exchangers offer significant advantages: they are self-contained systems that do not require a constant water source or complex plumbing. This makes them more cost-effective for remote locations, reduces maintenance associated with water scaling, and provides easier installation for mobile machinery and standalone industrial units.
What is the standard lead time for international orders (e.g., to Europe or North America)?
For standard models in our AH and AD series, we typically maintain stock for immediate dispatch. Custom configurations or large-scale project orders (like 4-set unit exports) generally have a lead time of 2-4 weeks. We are experienced in international logistics and ensure all documentation for CE compliance and customs is handled professionally.
Can MEISON air-cooled oil coolers be used in high-pressure systems?
Yes, our coolers are engineered for high-pressure environments. Most models support a static pressure up to 26 bar (approx. 377 psi). For systems experiencing frequent pressure spikes, we recommend installing a bypass valve (Check Valve) to protect the cooler core, ensuring long-term reliability in heavy-duty industrial applications.
Yes. Our high-grade aluminum cores and specialized seals are compatible with a wide range of fluids, including standard mineral oils, water glycols, and the increasingly popular biodegradable hydraulic lubricants.
