A power supply circuit containing a transformer which is used in a spray-drenched environment, for example, near a bathing pool or food processing plant, is cooled by heat exchange with circulating liquid. An electrolysis apparatus producing in situ chlorine for a pool has a passage through which pool water is pumped. A metal sleeve surrounds the passage and contacts a transformer and rectifier, all of which are surrounded by cast, insulating resin.
