COOL-LINE

COOL-LINE is a manufacturer of forced air oil coolers and hydraulic cooling solutions, serving industrial applications where heat removal from hydraulic and lubrication oil circuits is critical. The product line includes AC motor driven and hydraulic motor driven forced air oil coolers, as well as replacement fan assemblies. These units are designed to handle heat removal capacities ranging from 10 hp to 400 hp, with maximum flow rates from 50 gpm to 350 gpm and a consistent maximum pressure rating of 377 psi across the range. Connection options include SAE #16, 2-inch SAE 4-bolt flange, and 3-inch SAE 4-bolt flange, accommodating various system integration requirements. The AC motor driven models (e.g., A10-1) feature a 56C frame motor with dual-voltage capability (115/230V AC), while hydraulic motor driven models (e.g., HR25-0218, HR180-0050, HR260-0140, HR20-0218, HR400-0195, HR210-0140) are powered by the hydraulic system itself, eliminating the need for external electrical connections. Replacement fan assemblies (e.g., part number 8407.362.1079) are available to extend service life. 3G Electric stocks 47 SKUs of COOL-LINE products, providing datasheets and logistics support for global procurement. These coolers are suitable for use in industrial machinery, mobile equipment, and stationary hydraulic systems where oil temperature control is necessary to maintain viscosity, prevent degradation, and ensure component reliability. The forced air design uses ambient air as the cooling medium, making it a practical choice for environments where water cooling is unavailable or undesirable. No specific certifications or awards are claimed for COOL-LINE beyond the technical specifications listed.

Frequently asked questions

Common questions about COOL-LINE from 3G Electric.

What is the maximum operating pressure for COOL-LINE forced air oil coolers?

All COOL-LINE forced air oil coolers listed by 3G Electric are rated to a maximum pressure of 377 psi. This applies to both AC motor driven and hydraulic motor driven models across the entire heat removal capacity range, from 10 hp to 400 hp. Ensure your system operating pressure does not exceed this limit to avoid damage.

What connection types are available on COOL-LINE oil coolers?

COOL-LINE oil coolers are available with SAE #16, 2-inch SAE 4-bolt flange, or 3-inch SAE 4-bolt flange connections, depending on the model. For example, the A10-1 and HR20-0218 use SAE #16, while the HR180-0050 uses a 2-inch SAE 4-bolt flange, and the HR400-0195 uses a 3-inch SAE 4-bolt flange. Verify the connection type required for your system before ordering.

How do I select between an AC motor driven and a hydraulic motor driven COOL-LINE cooler?

Choose an AC motor driven model (e.g., A10-1) if you have a reliable electrical supply and prefer independent cooling operation. Choose a hydraulic motor driven model (e.g., HR25-0218) if you want to eliminate electrical wiring and use the hydraulic system's own flow to drive the fan. Hydraulic motor driven models are often used in mobile or remote applications where electrical power is limited.

What is the heat removal capacity range for COOL-LINE forced air oil coolers?

COOL-LINE forced air oil coolers offered by 3G Electric cover heat removal capacities from 10 hp (model A10-1) up to 400 hp (model HR400-0195). Intermediate capacities include 20 hp, 25 hp, 180 hp, 210 hp, and 260 hp. Select a model based on the heat load generated by your hydraulic or lubrication system.

Does COOL-LINE offer replacement parts for their oil coolers?

Yes, COOL-LINE provides replacement fan assemblies, such as part number 8407.362.1079. These are available through 3G Electric to maintain or repair existing coolers. Always verify compatibility with your specific cooler model before purchasing.

Does 3G Electric supply COOL-LINE products?

Yes — 3G Electric (S) Pte. Ltd. supplies COOL-LINE products. We stock the COOL-LINE catalog and supply genuine factory-original products with full manufacturer warranty and technical support.
