EKT Series

The EKT Series is an EK model designed with a tank flange that allows it to be installed directly in the hydraulic reservoir. 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. This compact design allows for simple integration and installation in the hydraulic power unit.

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.
