Reservoir-Mounted Finned-Tube Oil Cooler — Tank-Flange “Green Cooler”
The Thermal Transfer Products EKT Series is a reservoir-mounted, water-cooled finned-tube oil cooler for hydraulic power units. It’s a tank-flange version of the EK “Green Cooler” — the finned-tube bundle mounts through a flange directly into the hydraulic reservoir, so the cooler sits inside the tank instead of in an external cooling line. That eliminates external plumbing and mounting hardware, saves space, and simplifies integration into the hydraulic power unit.
Like the rest of the Green Cooler family, its aluminum finned-tube bundle provides increased surface area for high heat rejection while using less cooling water than a conventional bare-tube exchanger — a cost- and water-saving advantage where cooling water is limited or expensive. An optional Surge-Cushion® bypass protects the core during cold starts and flow surges when cold, high-viscosity oil or sudden flow spikes would otherwise stress it.
Because the bundle is immersed in the reservoir, the EKT is rated for a lower shell-side pressure than the in-line EK — a maximum working shell pressure of 75 PSI, tube pressure of 150 PSI, and maximum operating temperature of 250°F. TTP’s XSelector® sizing program — available online and as a mobile app — helps select the right model for your reservoir, oil flow, and cooling-water conditions.
