Just as in the cooling of charge air, environmental laws focus on “green” technologies, resulting in industry-wide R&D on alternative coolants such as ammonia or CO2, demanding higher pressures systems. Our thick-walled round tubes are used in condensers, evaporators and heaters, traditional or new innovative designs.

We can deliver in short lengths or long tubes, in perfectly round or D-shape, as plain tubes or ready to use, including slots, drill holes, baffles and welded-on connection blocks. Responding to the growing number of electric and hybrid vehicles, our newest development shows lengthwise slots to be used as collectors for contact battery coolers.
