EC Series

The EC Series is a robust version of the EK series with the same efficiency, handling flows up to 250 GPM. The aluminum finned tube bundle design provides an increased surface area that allows for optimal heat rejection with low water usage. An optional Surge-Cushion® bypass is available for cold start up protection or flow surges. With multiple material options to choose from, this series can used in a wide variety of applications.

Delta T Heat Exchangers is partnered with Thermal Transfer Products, a division of API Heat Transfer, to offer their pre-engineered heat exchangers. If you know your performance requirements, you can contact us by requesting a quote.
