    摘要： Equipment is provided having a distillation tank with a heater and a vapor offtake, with a condenser receiving the offtake vapor and delivering liquid condensate. A control system provides safety features including pressure and temperature responsive devices operative to shut off the heater and further including means for shut off of the heater when the tank is being filled. Still further provision is made for shutting off the heater under the influence of a float valve associated with the condensate discharge line and operative to shut off the heater under the influence of rise in level of condensate in the receiving vessel.
