Product Characteristics

 

AH Series 


            The cooler material is made of high strength plate-fin aluminum alloy and welded by vacuum welding with special technology.                                         
            The oil flow passage is welded with inner fins, the inner and outer fins are welded completely, the heat conduction is rapid, and the non copper tube type is comparable. Static test pressure: 35Bar working pressure: 20Bar. Maximum temperature: 120 degrees (excluding special fan Ma andambienttemperature). Application of fluid, and the Aluminum Alloy material to produce chemical reaction and corrosion, the water mixed with ethylene glycol, please contact 

 

Job stress interpretation:                                         
            When the pressure is static and the oil is returned, the dynamic pressure (dynamic pressure) is the instant of the pressure opening.                                         
            If the pressure gauge is used, the dynamic pressure must be multiplied by 4 times or more, that is, the pressure of the surface display should be less than 58ar, and the pressure will disappear in a moment, so we must pay attention to the observation! One action, one pulse!                                         
            In order to protect the cooler without rupture, when the cooler device in the oil return loop when (not recommended), need to install the valve or bypass unloading loop, and cooler in parallel, and that the pressure relief valve to open a sudden, priority unloading.

 

Even so, the aluminum alloy cooler still needs to withstand the small pulse for a long time. According to the circuit, the number of shocks may reach tens or millions of times, and the rupture risk must be borne by the circuit designer!                                         
                               
            Recommend the best way to use:                                         
            Using a small pump, cooling system with the use of independent extraction                                         
            The fuel tank is supplied with an oil cooler, which makes it an independent cooling circuit and can not be used in this device. It is called the kidney circuit of the tank.

 

AW Series 


            Suitable for high pressure piston pumps or vane oil drain cooling (Drain) or independent loop.


AL Series 


            This series is not under any pressure within the tube surge cooling with the use of DR port. Only applicable to variable vane pump, using pressure below 708ar drain port. (Drain)

Technical Bulletin

 

In the oil pressure system, the use of air-cooled oil cooler is gradually increasing compared with the water-cooled cooler. In addition to some cooling requirements below room temperature, it is well known that air-cooled cooling is the best choice.

*Due to the poor performance of the air cooled cooler at room temperature, it can be used in conjunction with the refrigerator. At least half of the precious energy is saved. Please contact the dealer.
