Warehouses, Service Shops, and Distributors in Principal Cities CONTROL FOR HEATING, VENTILATING, AND AIR-CONDITIONING MOTORS General Electric offers a complete line of standard manual and automatic controls for all types of motors driving compressors, fans, pumps, etc. Publications describing these items, as well as such control accessories as pressure governors, pressure switches, float switches, electrically operated valves, and indicating selsyns, are available on request. For special applications, G-E control to meet your exact requirements can be designed. Most frequently, however, the needs of the air-conditioning industry are best served by one of the many possible G-E "packaged" control combinations desig nated as Cabinetrol* equipments. Typical Cabinetrol unit, shelving open motor-starter panels The Cabinetrol system of motor control is based upon the use of,standardized enclo sures equipped with standard cofltrol devices. General Electric can build quickly most air-conditioning control systems--simple or complex--by properly combining standard control'units and accessories into the required number of basic Cabinetrol sections. If future expansion should require further control equipment, additional Cabinetrol units can easily be added to the basic system. The standard enclosures used in the Cabinetrol system will mount standard motor starting devices up to and including NEMA Size 4. Ample space, is provided for incom ing-line, feeder, and metering equipment. Bulletin GEA-3856 details more fully the advantages of this new system of centralized low-voltage control. v Th6 General Electric Company will gladly assist in the solution of any electrical problem related to heating and ventilation.
