Temperature Control A Self-Operating Regulator for Control of Compartment Temperatures Between 60 Deg. and 100 Deg. Fahr. The Powers No. 18 Regulator shown above is a self-contained unit, not as sensi tive in operation as the' air pressure types but inexpensive' and capable of good general control between the limits of 60 deg. and 100 deg. fahr., where such control can be obtained by the operation of a single valve regulating the heat supply. The control of this valve is gradual and' an efficient return line vacuum system is essential. This regulator is used in shops, offices, warehouses, storage rooms, low tempera ture drying rooms, small ventilating units, greenhouses, etc. It is easy to install and is very DUR- ABLE. Gives true gradual control. By changing the position of the adjusting weight; different temperatures over a 20 deg. fahr. range at the thermostat may be secured. . The flexible connecting tube may be of any length up to 75 feet or with the smaller valves 100 feet, and is usually of lead closely armored with galvanized steel wire. Armored copper tube can be furnished where conditions of vibration require its use, as in the control of fan ventilating units. Standard flexible lead connecting tube of 50 feet will be sent unless otherwise speci fied; excess if any, can be coiled up near 644 valve or damper motor. Additional tube length will be furnished at 20 cents net per foot. For control of ventilating units or under other conditions of vibration, copper tube, armored, must be used instead of lead-- such armored copper tube will be fur nished at an extra net charge of 20 cents per foot for first 50 feet, and 30 cents per foot for excess. Always specify desired operating tem perature and steam pressure, and state whether latter is constant or fluctuating. Bulletin 145 gives complete infor mation.
