Multicell Radiator Corporation Lockport, N. Y. Manufacturers of Multicelli Unit Heaters and Multicell One-piece Pur r- "1 Heating Surface for Special Heating and Refrigerating PurBosiPH Multicell 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 accprdion-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, and self-cleaning, thus maintaining their original high efficiency without attention. Multicell Fans do not require special wiring. Multicell Unit Heaters are unusually light. They are easily installed and they give a large heat output per pound of weight. In addition to heating factories, Multicell Unit Heaters have many other uses. When equip ped with variable speed motors, they are especially adaptable to churches, auditoriums, etc. Multicell Unit Hegters 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 .
