Finned Tube Bundle Shell & Tube Water to Oil Cooling

The EK Series – the ‘Green’ cooler – is the most efficient heat exchanger offered in the water cooled series.  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.  Sea water service options are also available.  The low cost, compact design is ideal for general purpose hydraulic power unit installations.
