Abstract: In order to achieve an increase in energy efficiency and a faster quenching of the workpieces, a device according to the invention is proposed for the treatment of metallic workpieces with cooling gas, comprising a horizontally arranged cylindrical housing (1) with at least one closable opening for the introduction and extraction of the workpieces to be treated, with a quenching chamber (2) located inside the housing (1) for receiving the workpieces to be treated, with two high-performance fans (5 and 6) arranged laterally and outside the quenching chamber (2) for guiding a cooling gas through the quenching chamber (2) and with two heat exchangers (11 and 12) for cooling the cooling gas, that heat exchanger (11 or 12) is respectively associated with a high-performance fan (5 or 6) and that closable guide devices (17 or 18) are arranged above and below the quenching chamber (2).
