'TAE MARINE REVIEW THE PATENT | ve FEED WATER HEATER : Combines the greatest efficiency in the smallest = iS space at the least cost. Condenses all the auxiliary exhaust steam in heating the feed thereby relieving the main condenser. Requires but one feed ee Delivers feed water at approximately the temperature of the ae the heater. The copper coils are very elastic, 'overcoming ie C age due to expansion and contraction. These tubes are a : accessible and can be readily removed or replaced; they are sta a ' ard and interchangeable. an The Multicoil Heater is absolutely automatic in action and once adjusted needs no further attention. QUIGGINS PATENT EVAPORATOR With its light weight and compact construction it combines (exclusive feat- ures that make it superior to any other evaporator. Made to fit any space. No extra room required for scaling. Scaled readily without removing coils. Its capacity can be increased 25% without increasing space. Write for complete description of these Engineers' Necessities.
