NESBITT SILL-LINE RADIATION NESBITT UNIT HEATERS are designed to circulate large volumes of air at comparatively low temperatures, assuring quick heating. High-capacity perimeter heating in an Ratings of Nesbitt Unit Heaters are based on tests made in accordance with attractive 16-gage wall-hung enclosure standard test code of Industrial Unit Heater Association and ASHAE. :m for use in schools, hospitals, offices, showrooms, etc. Made in five casing PROPELLER FAN UNIT HEATERS Btyles with one-piece back panel for true, rigid alignment; seven lengths from 2 ft to 8 ft; choice of finishes. Full range of accessories and sleeves eliminate on-thejob cutting. Choice of ten heating ele ments with CODE approved ratings from 2.9 to 12.1 sq ft EDR. Publication 80-1. At Featuring universal heating elements of continuous tube design, each size unit gives a comparable range of capacities with either steam or hot water. Made for high temperature drops, low water rates for installation economy. Small physical size for comparable Btu output saves space. Sturdy steel casings with bakea-on gray-green hammertone finish for lifetime beauty. Flush-to-ceiling mounting permitted by male pipe connections extending through casing rear. Sealed-for-Iife motors in most models. Balanced aluminum fans with large NESBITT HEATING AND COOLING SURFACE standard blade areas assure gradual, quiet, efficient air delivery.
