  • Reduce the complexity of your genset installation
  • Provide a turnkey genset, including radiator, to your customer
  • Lower total cost of ownership (TCO)

Copper-Brass Radiators

Our durable and versatile line of copper-brass heat exchanger technology can be applied to any set of operating conditions and is available in a wide range of sizes and types.

BOLTED PLATE-FIN RADIATORS

With thousands of our Bolted Plate-Fin radiators in the field, you won’t find anyone with a better track record of reliability and customer loyalty. 

  • Pre-engineered or custom engineered to your exact specifications
  • Wide product range
  • Sizes from 3 sq. ft. 120 sq. Ft. – Horizontal radiators
  • Sizes from 3 sq. ft. 95 sq. Ft. – Vertical radiators
  • Dimpled tubes provide superior performance
  • High-efficiency louvered or non-louvered fins
  • Variety of heavy duty core types designed for any environment

  • Variety of core types to fit your application
  • LF-20 lead-free construction for long, worry-free service

MECHANICALLY BONDED PLATE-FIN RADIATORS

By forming a permanent mechanical bond joint between the tubes and steel header, we’ve created the ultimate in copper-core technology. 

  • Multiple thermal expansion designs to reduce tube stress
  • Sizes from 3 sq. ft. 120 sq. Ft. – Horizontal radiators
  • Sizes from 3 sq. ft. 95 sq. Ft. – Vertical radiators
  • Ideal for heavy duty applications, and sub-zero temperature site conditions and consequential thermal shock
  • Ideal for high shock and vibration applications
  • Ideal for sub-zero temperature site conditions and consequential thermal shock
  • Ideal for High Pressure applications
  • The “Gold-Standard” for rail locomotive applications
