IN ONE PREFAB PACKAGE ARTICULATED UNITS Units with unlimited capacities are famished for standard, doable duct or multizone distribution systems. Designed for each piftienlar application, they incorporate coordinated equipment to t within the space available. All units are factory test-assembled to assure fit of parts prior to shipment. We call them ARTICU LATED UNITS. COMPONENTS A typical system often combines air mixing, filtration, washing, cooling and heating, hamidifying or dehamiaifying and air circu lating equipment. More complete systems may also indade the refrigeration compressor, water chiller, evaporative condenser, pomps and boiler with all being enclosed in a factory insulated casing Blow-through multizone systems also require outlet air dampers for mixing hot and cold air streams for each zone. HOUSINGS Unit housings are assembled using A & R factory insulated panels. Available iD indoor or outdoor weatherproofed construc tion, the panels consist of an interior galvanized steel sheet to which is applied the insulation, aluminum vapor seal and outer protective sheet of tempered hardboard. For outdoor use an addi tional weatherproof skin of aluminum is added. To save additional cost, the machine room floor may be used as the bottom of each, enclosure or.an insulated drip pan may be included. ADVANTAGES Articulated units are custom engineered to suit the performance fequirenients and space limitations of each particular application. AH parts are selected to work in co-ordination with the rest of the system. Office time and effort by the.purchaser are reduced in adopting articulated unit construction. One purchase order covers materials and services normally requiring a number of separate contracts. The factory insulated housings do away with the usual mess of field insulation and plastering. This may be an important factor, particularly in older buildings such as department stores, etc-, where valuable stocks of merchandise cannot be removed. Prime coated before leaving the factory, the exterior presents a continuity and neatness of appearance which needs no field painting unless scratched or marred in handling and erection. The panel type construction permits sections of units to be dis mounted quickly and easily where it is necessary to remove bulky internal parts for repair or replacemenL CATALOGS For further information on A & R Articulated Units or Fat Insulated Panels, write direct to main office in New York, or tact factory representative in your area. f f5 I $ & !.: \.
