Industrial Radiator Buying Guide

Choosing the right radiator starts with understanding your engine’s cooling load, operating environment,
and mounting configuration. Industrial engines and generator sets require radiators that maintain temperature
under continuous or heavy-duty operation.

Key specs to evaluate:

• Cooling capacity (BTU/hr)
• Core size and airflow requirements
• Material type (copper/brass, aluminum, steel)
• Mount style (remote, engine-mounted, skid-mounted)
• Application: diesel engines, natural gas engines, marine engines, generator sets

Whether you’re replacing an OEM radiator or upgrading an older system, Depco’s specialists can help match
your application. Contact us to confirm compatibility and ensure proper fit and cooling performance.
