Branch Offices in Principal Cities of United States and Canada THERMOLIER GRINNELL UNIT HEATERS Thermolier is a quality unit heater. It is backed by Gnnnell's 60 years of varied heating experience. It is so soundly designed and engineered that no changes in its basic construction or op eration have been necessary since its in troduction years ago. Basically, all models incorporate the same quality features. However, the heating element of the Horizontal and Vertical delivery types consist of a single header with a series of copper, pitched, finned U-tubes, while the Textile type utilizes a single header with a series of copper, pitched, webbed U-tubes--par allel to one another. Thermolier motors are not standard stock motors but are built to exact spec ifications for unit heater duty. This assures maximum life at maximum opera ting efficiency with the minimum of electrical input. Fans have aluminum blades with special steel hubs and are made to specifications to insure accurate balance, minimizing noise and vibration. Supply and return pipes.are both on the same side of the unit, assuring com pactness, neatness and economy in in stallation. Each Thermolier is fur nished with adjustable swivel couplings which provide an easy and practical method of hanging the unit and facilitat ing adjustment after erection. The housing of all units are formed from heavy gage steel and are finished in attractive artmetal slate grey. THERMOLIER CONSTRUCTION FEATURES that save trouble and money Use of a plain thermostatic trap, the simplest and least expensive kind of trap, is practical because of Thermoliers's ex clusive internal cooling leg. Maximum capacity provided at all times and annoying destructive, water hammer eliminated by built-in pitch of tubes and internal cooling leg which as sures continuous drainage of condensate. Damaging strains caused by expansion and contraction eliminated by "U" type expansion tubes. Safety and durability assured with leak-proof tube-to-header construction. Five other important features.
