Abstract
A quenching device is described that includes at least one chamber that can be filled with quenching gas and that has a blower wheel for circulating quenching gas, in particular a quenching chamber and/or a flow channel, a drive motor, situated outside the chamber, for driving the blower being allocated to the blower wheel. The drive motor is coupled to the blower wheel so as to transmit torque via a coupling that operates in contactless fashion. Also described is a related quenching method.
