<p>A condenser comprising an outer sheath for circulating refrigerant fitted wih an axial rotating shaft carrying blades, pref. with terminal lips to sweep the condensate to the outlet duct, with articulated joints to centrifugally throw the blades close to the wall surface to remove adherent deposits condensed at the inner surface, without interrupting the condensation cycle. The blades do not touch the surface but adjust to the thickness of the deposit and may be used continuously or intermittently.</p> |
