Heaters, Unit CarrierYork Corporation A Division of Carrier Corporation 1541 Sansom Street Philadelphia Branch Offices and Representatives in all Principal Cities CARRIER ATMOSPHERIC CABINETS for Stores, Offices, Etc. The Carrier Atmospheric Cabinet This is a complete, self-contained air conditioning unit, combining an attractive piece of furniture with year-round utility. In winter it provides evenly heated, ade- uately humidified, gently circulated Itered air; in summer, when used in con junction with a refrigeration machine or when connected with a building's regular source of refrigeration, it distributes cool, clean, properly dehumidified air through out the room in which it is installed. Heat ing only, cooling only, or both heating and cooling may be combined, depending on the type cabinet selected. Range of Applications--The Carrier Atmospheric Cabinet has an extremely wide range of applications, and proves a profitable investment from the standpoint of health, comfort, productiveness, patron age and profits. Ideal for business, doctors' and dentists' offices, small retail stores, barber shops, cafeterias, tea rooms, bakeries, candy shops, etc. - - (Left) Complete internal cabi net assembly, showing heating coiU, humidifier, air filter and control damper P (Right) External and internal cabinets assembled ready for in stallation, showing at the right the outdoor intake, which he easily adjusted to varying sill heights already available for the steam or hdt^ water heating system, and adding small supply and drain lines for humidification.' To provide for cooling, the only additional piping required is the installation of supply and return lines to and from the source of refrigeration. External Cabinet . Cover--An Art Metal removable enclosure, walnut grain finish, baked enamel undercoat, with heavy steel grille top. This cabinet con ceals all fittings and connections and is provided with access doors.

A small motor operates the two fans, and may be connected to Carrier-York Corporation Healers, Unit Carrier-York Corporation A Division of Carrier Corporation 1541 Sansom Street Philadelphia Branch Offices and Representatives In all Principal Cities SUPER-CONTROL HEAT-DIFFUSING UNITS FOR INDUSTRIAL HEATING or an inverted type, all that is necessary is to revolve the bearing plates and reverse the coil. Temperature Regulation--SuperControl regulation gives a constant balance between heat requirements of the room or building and the heat output from the units, which insures minimum overheating of the upper areas and maximum fuel economy. In addition, the constant air circulation produces an extremely even temperature distribution over the entire area served. . Temperature regulation may be either pneumatic, electric or manual. No. S34 Super-Control Heat-Diffiueing Unit Super-Control Heat-Diffusing Units These units are convertible. Thus, should it become necessary or advisable through re-arrangement of plant layout to change the units, from floor mounted to suspended, or vice versa, the same units may be re-used, since by removing the legs a floor mounted unit becomes a verti cal suspended unit. To make the vertical suspended unit a into horizontal suspended Construction--The fans are of the non-overloading, housed type. Each fan wheel is balanced statically and each fan and shaft assembly then balanced dynamically, insuring ' smooth operation. Patented feature permits complete- fan assembly being inserted in unit without disturbing this rotating balance. Kroy Unit Heaters-- Disc Fan Type Kroy suspended Unit Heaters are available in a wide range of capacities, and may be had with floor recircutating boxes where desired.

A suitable pipe fine drop must be added in determining the pressure to be carried at the boiler.. When air is to enter the unit at a temperature below Ireesing, the steam pressure on the beating surface should be maintained at not less than S lb. gauge.
