Heating Systems Hot water Bell and Gossett Company Morton Grove, Illinois HYDRO-FLO HOT WATER SYSTEMS AND SPECIALTIES B & G Booster Pumps The B & G Booster is the basic unit of a B & G Hydro-Flo Forced Hot Water Heating System. It is built as a hori zontally driven unit for sound engineer ing reasons which have demonstrated their practical value in thousands of installations. This construction makes possible many desirable, exclusive fea tures. For example, the patented water tight Seal eliminates need for a stuffing box. This Seal positively prevents entry of water into bearings. Shaft is of highly polished, hardened machine steel. The close-fitted Impeller makes every revolu tion count by holding water slippage to a minimum. B & G Flo-Control Valves - This valve, installed in the main, shuts off circulation to radiators when heat is not needed, permitting summer opera tion of a B & G Indirect Water Heater. It also helps maintain a uniform room temperature during the heating season. B & G Monoflo Fittings B & G Monoflo Fittings permit the use of a single pipe main instead of the conventional flow and return lines. They are installed at the junction of the radiator risers to the single main and assure the diversion of the proper amount of heated water into each radiator. Savings in space, labor and materials are obviously effected. Avail able in cast-iron and copper. l B & G Motorized Valves Thermostatically operated valves teed toTcontrol boiler water flow through individual circuits of zoned heating B & G Boosters have a genuine oil - circulating lubrication system--one of the greatest reasons for quiet, depend able, economical operation. Oil is drawn up from the oil well by wool fibre wicking and dropped on the horizontal bearing surfaces. Medium grade motor oil is used and only a few drops at infrequent intervals are required. B & G Universal Pumps Designed for forced hot water heating systems in apartment and office build ings, factories, schools, etc. The Uni versal is not an ordinary centrifugal pump, but is specially designed to assure SEE THE B & G HANDBOOK FOR COMPLETE DESIGNING DATA quiet operation, so essential in heating system applications. 1598 Bell ana Gossett Company neaung oystems Heat Transfer HOT WATER SYSTEMS AND SPECIALTIES B & G Relief Valves Designed and built to ASME require ments. Tested by National Board--la belled. with ASME symbol. For relieving excess boiler pressures in hot water heating systems, and in the lines of service water systems. B & G Relief Valves have the design features which assure dependable service. B & G Type "WU" Heat Exchangers B & G Reducing Valves All working parts brass, with built-in strainer. Easily adjusted to meet vary ing building heights. Also high pressure reducing valves for.protection of plumb ing fixtures. B & G Comfort Control System A shell and tube heat exchanger with hot boiler water pumped through the shell by a B & G Booster, making pos sible big capacity in a small unit. Pumping boiler water through the heater also affords excellent temperature control and permits use of much smaller pipe and fittings. B & G Type "StJ" Heat Exchangers For heating water with steam. Ideal for industrial plants or wherever large volumes of hot water are required con tinuously for service water supply or process work. No storage tank required --the large heat transfer surface in these units heats water instantly as needed. Available in a wide range of capacities. B & G Centrifugal Pumps Outdoor type, wind-compensating tem perature control. The Regulator pro jects through the building wall, with the indoor end warmed by water in the radiation circuit. A small amount of this heat is conducted to the outside end, where it is dissipated at a rate dependent upon temperature and wind velocity. This heat dissipation governs the Control Valve, which permits hot boiler water to enter the system in required amounts. Design and construction based on years of experience in the industrial field. Rugged, compact units--built to withstand strain of continuous opera tion. Semi-open or enclosed impellers-- motors flexible coupled or integral with pump. Series 1522 illustrated. < B & G Refrigeration Components A very complete line of direct expansion evaporators, condensers, liquid re ceivers, combination liquid receivers and subcoolers for refrigeration and air conditioning. Special alloys may be incorporated in the units for those critical heat transfer applications. 1599
