Webster Service '--delivered through more than 50 Branch Offices, places at the disposal of engineers, architects, and heating con tractors accurate, comprehensive information resulting from the extensive experience of this organization.' Webster Vacuum Systems --are particularly suited to large buildings, or where "process" steam is used and the exhaust utilized for'either direct radiation, or in combination with blast coils or unit heaters ... operating on either low-pressure live steam or exhaust steam, or a combination of both. Webster Type "R" System A two-pipe, open return line, low pressure steam beating system adaptable to almost every type of building, except the very largest, where Webster Vacuum Systems are used. For installations from 500 to 32,000 aq. ft. oifdirect radiation. The only limitation is the necessity for a basement or other depression so that the boiler may be placed with ita water . .line below the level of water of condensation flowing back to it. The combination of the Webster Boiler Return Trap and Webster Vent Trap incorporated in this system pro vides maximum safety with open return line simplicity. Operation: Pressure at the boiler is kept uniform by the. Webster Damper Regulator. Steam is admitted to radiators by Webster Modulation Valves or Webster Sylphon Valves. Condensation and air are completely discharged through Webster Return Traps which insure absolute silence and prevent waste. Air and condensation are carried to Webister Basement Equipment consisting of the Webster Boiler Return Trap and Vent Trap in combination. Air escapes through the Webster Vent Valve. The Webster Boiler Return Trap returns water to boiler whenever pressure exceeds a few ounces. TABLE I. Webster Type "R" System Basement Equipment Size of Rating, Sq. Ft.
