A welded steel structure is a guarantee of strength that brazed coolers cannot match. ASTECHNIK bimetallic tube coolers are designed for hydraulic power systems, where high oil pressures and dynamic loads are a daily occurrence — not an exception.

Hydraulic cylinders, control valves, and hydraulic power units operating under high working pressures — where sudden pressure spikes and hydraulic shocks rule out the use of standard brazed coolers.
Presses, injection molding machines, machine tools, and other equipment with intensively operating hydraulic systems — requiring reliable oil cooling for thousands of operating hours without the risk of leakage.
Wherever a standard oil cooler has already been replaced due to leaks or pressure-related damage — the welded bimetallic construction provides a permanent solution.
Bimetallic tubes combine two layers of materials with complementary properties — the outer steel layer provides mechanical strength and resistance to high pressures, while the inner layer of metal with higher thermal conductivity ensures efficient heat transfer. The welded housing construction eliminates the typical weak points of brazed coolers — joints that may leak under high pressure. The result: an oil cooler that operates reliably where other solutions fail.
