Dephlegmator (cooler) XL

Device for condensation of vapors during rectification and distillation. Inside is a spiral along which the refrigerant flows. Condensed reflux can be taken out completely, as during distillation, or partially, as during rectification. Compared with a reflux condenser (link to a small reflux condenser), it has a larger area of the cooling element, which allows distillate to be removed at high capacities.
