Line voltage Ther mostat for Unit Heater- and AirConditioning In stallations. Single speed fan control-cover re moved showing visible dial. 8 EXCLUSIVE FEATURES OF WHITE-RODGERS HYDRAULIC- ACTION TEMPERATURE CONTROLS Dual Immersion Control--LimitCirculator or Summer-Winter service. * T. May be mounted at any angle or position, above, below or on level with control point. 2. Hydraulic-Action Principle incor porating solid-liquid filled bulb and capillary provides expansion force com parable to that of a metal bar. 3. Diaphragm motion uniform per de gree of temperature change. 4. Power of solid-liquid charge permits unusually sturdy switch construction resulting in positive contact closure. 5. Heavier, longer-wearing parts are possible because of unlimited power. Solenoid Gas Valve -- High plunger torque and silent operation. 6. Dials are evenly and accurately cali brated over their entire range because of straight-line expansion. 7. Controls with remote bulb and capillary are not sensitive to change in room temperature. Accuracy of control is not affected by temperature changes in surrounding area. 8. Not affected by atmospheric pres sure. Works accurately at sea level or in. the stratosphere without compen sation or adjustment. Diaphragm Gas Valve with puff bleed and built-in me chanical limit control. 1146 Low Voltage Room Thermostat--an ticipating type. Ex plosion-Proof Thermostat for hazardous locations --remote type. Steam Pressure Control--for safety limit service. International Heating & Ventilating Exposition THE AIR CONDITIONING EXPOSITION Permanent Address--Grand Central Palace, New York 17, N. Y. EXPOSITIONS HELD The first in Philadelphia, 1930. The second in Cleveland, 1932. The third in New York, 1934. The fourth in Chicago,-1936. The fifth in New York, 1938. The sixth in Cleveland, 1940. SEVENTH EXPOSITION TO BE HELD IN CLEVELAND The first post-war Heating and Venti lating Exposition will be held in Cleveland at Lakeside Hall, January 27 to 31, 1947. This will be the first, of a new series, now scheduled on an annual basis. Response to the initial announcement indicates that manufacturers have a keen interest in exhibiting their newest products of re search and development. There has developed a tremendous pentup demand for new equipment that will be a challenge to the industry_.The manner in which you meet this opportunity will be a guide to your future progress. As in the past, the Exposition will be ready to help you by offering a timely, quick and effective means of renewing old contacts, developing new ones, and actually demon strating your products. - These expositions have been and will be held coin cident with the Annual meetings of the American Society of Heating and Ventilating Engineers and are directed by the International Exposition Company, under the auspices of the A.S.H.V.E.
