THERMOLIER--GRINNELL UNIT HEATERS Horizontal--Vertical--Textile Types Horizontal Ddivery Type Regular Construction--finned tubes Textile Construction--udbei tubes Vertical Delivery Type Thermolier, the Grinnell quality Unit Heater, is available in three types . . . the regular Horizontal delivery type, the Textile type and the Vertical delivery type. The heating element of the Horizontal and the Vertical delivery types consists 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. Basically, all three types incorporate the same quality features. Among these are the patented Internal Cooling Leg.which assures continuous drainage of condensate, and the Single Header U-Tube construction which compensates for expansion and contraction strains. Thermolier motors are not standard stock motors but are built to exacting speci fications for unit heater duty. This assures maximum life at maximum operating 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 piping are both on the same side of the unit, assuring compact ness, neatness and economy in installation. Each Thermolier is furnished with ad justable swivel couplings which provide an easy and practical method of hanging the unit and facilitate adjustment after erection. The housings of all units are formed from heavy gauge sheet steel and are finished in attractive artmetal slate gray. 1134 Grinnell Company, Inc.
