Abstract: <PICT:0642845/III/1> An evaporator of the vapour-compression type is connected to an auxiliary evaporator which is heated by at least one electric immersion heater and supplies vapour to a heat-exchanger in the liquid space of the main evaporator.  The auxiliary evaporator may be fed with distilled water but, in the evaporation of a natural water containing only a small amount of solid matter, the raw water is supplied to the auxiliary evaporator; and after partial evaporation therein, is then introduced into the main evaporator. In this way, additional heat is supplied by an electric heater and the formation of scale thereon is reduced to a minimum. Vapour from the auxiliary evaporator may also be supplied to the vapour space of the main evaporator.  Raw water is pumped through heat-exchangers 10, 8 and through control valve 12 into main evaporator 1.  The top of evaporator 1 is connected with the suction side of compressor 4 which discharges compressed vapour into coil 2.  Distillate leaves the evaporator through connection 7 and is cooled in heat-exchanger 8. Blow-down is removed through connection 9 and is passed through heat-exchanger 10.  Auxiliary evaporator 13 contains electric heaters 17, and is supplied through float-operated control valve 16, with distilled or fresh raw water from tank 14.  The top of the auxiliary evaporator is connected by connections 18 and 20 respectively to the discharge from compressor 4 and to the vapour space of the main evaporator 1.  In another embodiment, the connection 18 is led to an independent coil in the main evaporator.  Provision may be made for varying the number of heating elements in use to suit the particular operating conditions.
