Frequently asked questions

Common questions about COOL-LINE from 3G Electric.

What is the maximum pressure rating for COOL-LINE hydraulic motor driven forced air oil coolers?

The COOL-LINE forced air oil coolers listed in 3G Electric's catalog, including models HR20-0218, HR25-0218, HR45-0372, HR55-0050, HR100-0050, HR210-0140, HR400-0195, and HR500-0195, all have a maximum pressure rating of 377 psi. This rating applies to the hydraulic circuit in which the cooler is installed. It is important to ensure that system pressure does not exceed this value to avoid damage to the cooler. The pressure rating is consistent across the range, allowing for uniform specification across different capacity requirements. When selecting a cooler, verify that the system's operating pressure, including any pressure spikes, remains within this limit. For applications with higher pressure requirements, consult 3G Electric for alternative solutions or additional pressure protection measures.

What flow rates are available in the COOL-LINE HR series oil coolers?

The COOL-LINE HR series includes models with maximum flow rates ranging from 50 gpm to 350 gpm. Specifically, the HR20-0218, HR45-0372, and HR55-0050 have a maximum flow of 50 gpm; the HR25-0218 and HR100-0050 are rated for 80 gpm; the HR210-0140 handles up to 200 gpm; and the HR400-0195 and HR500-0195 support up to 350 gpm. These flow rates indicate the maximum volume of hydraulic oil that can pass through the cooler while maintaining effective heat transfer. Selecting a cooler with an appropriate flow rating ensures that the oil velocity is within design limits, which affects both cooling performance and pressure drop. It is advisable to match the cooler's flow capacity to the system's maximum flow to avoid excessive pressure loss or reduced cooling efficiency.

What is the heat removal capacity of the COOL-LINE HR500-0195 oil cooler?

The COOL-LINE HR500-0195 is designed to remove 500 hp of heat from hydraulic oil. This is the highest capacity model in the COOL-LINE range available through 3G Electric. It supports a maximum flow of 350 gpm and a maximum pressure of 377 psi. The unit features a 3-inch SAE 4-bolt flange connection. This model is suitable for large hydraulic systems where significant heat generation occurs, such as in heavy industrial machinery, large power units, or high-power mobile equipment. When specifying the HR500-0195, consider the system's heat load, available space, and connection requirements. Proper installation and maintenance are essential to achieve the rated heat removal capacity.

What connection type is used on COOL-LINE HR400-0195 and HR500-0195 oil coolers?

The COOL-LINE HR400-0195 and HR500-0195 forced air oil coolers use a 3-inch SAE 4-bolt flange connection. This flange type is commonly used in hydraulic systems for high-flow applications, providing a secure, leak-resistant connection. The SAE 4-bolt flange is standardized, allowing for compatibility with corresponding flanges on hoses, tubes, or manifolds. When installing these coolers, ensure that mating flanges meet SAE specifications and that proper seals and bolts are used. The flange connection facilitates assembly and disassembly for maintenance. For other COOL-LINE models, connection types may vary; consult the individual product datasheets for details.

Can COOL-LINE oil coolers be used in mobile hydraulic equipment?

Yes, COOL-LINE hydraulic motor driven forced air oil coolers are suitable for mobile hydraulic equipment. Because they are driven by the hydraulic system's own flow, they do not require a separate electrical power source, which is advantageous in mobile applications where electrical supply may be limited. Models such as the HR20-0218, HR25-0218, HR45-0372, HR55-0050, and HR100-0050 are commonly used in mobile machinery. These coolers help maintain oil temperature within optimal ranges, protecting hydraulic components and extending oil life. When selecting a cooler for mobile use, consider factors such as vibration, ambient conditions, and space constraints. 3G Electric can provide specifications to assist in matching a COOL-LINE cooler to the mobile equipment's requirements.

What information is needed to select a COOL-LINE oil cooler for a hydraulic system?

To select an appropriate COOL-LINE oil cooler, gather the following system parameters: heat load (hp or kW) to be dissipated, maximum hydraulic flow rate (gpm), maximum operating pressure (psi), and available mounting space. Additionally, consider the desired oil temperature reduction, ambient air temperature, and connection type. The COOL-LINE range offers models with heat removal capacities from 20 hp to 500 hp, flow rates from 50 gpm to 350 gpm, and a maximum pressure of 377 psi. Match these specifications to your system's requirements. For assistance, 3G Electric provides datasheets and can help identify the correct model based on your application details. Proper selection ensures efficient cooling and reliable operation.
