f ,Heaters Unit Multicell Radiator Corporation Lockport, N. Y. Manufacturers of Multicell Unit Heaters and Multicell One-piece Pure Copper Heating Surface for Special Heating and Refrigerating Purposes M ulticell Heating Surface is made of one piece seamless copper by an exclusive and patented process of electrical deposition. The surface is cellular in design and has an accor- dion-like pattern which allows it to absorb expansion and contraction within itself. Every Multicell section is tested with 100 pounds air pressure under water. Multicell Surface is heavily tinned inside and outside to make it proof against corrosion. The accordion-like action of the Multicell section is made possible by the diagonal pat tern of its one-piece sections. This feature takes care of any expansion or contraction. Multicell Frames are of all cast-iron con struction with flow and return headers cast integral with upper and lower frame members respectively. This rigid all cast frame absorbs all piping strains and will not deteriorate from corrosion. In case of accidental damage individual sections on Multicell Heaters can easily be removed simply by uncoupling one union at each end of section. Multicell Sections have ample water ways. They present so little resistance to steam flow that pressures are practically the same at inlet and outlet. Multicell Elements will not gather dust and lint. Their surfaces are smooth and self cleaning, thus maintaining their origi nal high efficiency without attention Multicell Motors do not require suspension poos special wiring.' In addition to heating factories. Multicell Unit Heaters have many other uses. When equipped with variable speed motors, they are especially adaptable to churches, 'B LSI jSjy * auditoriums, etc. Multicell Unit Heaters are tested and rated in accordance with the standard code for testing and rating steam unit heaters, adopted January 1930, by Industrial Unit Heater As sociation and the American Society of Heating and Ventilating Engineers.
