392 Heating System* bm tu>. TACO HEATERS, INCORPORATED 1160 Cranston Street, Cranston 9, Rhode Island Corporate Office: 324 Madison Avenue, New York. In Canada: Taco Heaters of Canada, Ltd., 4 Gilead Place, Toronto 2 Serving the Hydronic Industry Since 1920 Rigid control of quality, advanced designs, nation-wide service and engineering assistance are your assurance that you can specify Taco with complete confidence in product performance. TACO LP PUMPS TACO MP PUMPS TACO WATER HEATERS, CONVERTERS. AND CHILLERS A line of single stage centrifugal pumps with: relatively few sixes; many inter changeable parts; broad range of per formance; high efficiencies. A base mounted line of pumps with the rugged dependability large installations require. Taco Converters and Water Heaters provide hot water and radiation for com mercial and institutional heating pur poses. Chillers are designed for chilling water in the air conditioning and re frigeration fields. TACO CIRCULATOR Packed with quiet power and proven performance; sizes V* in. through 3 in. TACO 170 CENTRIFUGAL PUMP Excellent for cooling tower jobs; airconditioning installations... wherever a small top-quality built centrifugal pump is needed. TACO VENTURI FITTINGS Powerful suction action draws water through radiator for positive circulation. May be used for above or below main radiation. Taco Super Venturis save you money by reducing branch sizes, copper tubing, pipe fittings and labor costs. TACO AIR-SCOOP Scoops air bubbles from hot water sys tem by a series of baffles. Air is then vented to either atmosphere or expan sion tank. When system is first filled ... vent radiators and high points once ... no return to job! TACO PERFECTA Outstanding circulator; so quiet you won't believe it's running. TACO FLOW REGULATOR Limits water flow to specified require ments. TACO TEMPERING VALVE Guards against excessively hot do mestic hot water. Mixes cold water with hot water from Taco Tankless for storage heater to provide tempered water at fix tures. TACO AUTOMATIC AIR VALVES TACO FLOW CHECK Easily installed in either angle or hori zontal position, the Toco Flow Check prevents hot water from entering the system when the thermostat stops the circulator. TACO PANELTROL Adjustable to deliver water to radiant heating panels for any'temperature be tween 110F and 15QF even though boiler water is kept at higher temperature for summer-winter hot water. Taco-Vent for water systems is leakproofed. It has a porous plug that limits the flow of water through valve. The Steam Vent eliminates pinging, clicking or hissing. TACO RELIEF AND REDUCING VALVES Automatically maintains sufficient wa ter and pressure in system. The Taco ASMS Relief Valve handles 80 percent of all hot water heating jobs, ana is set to relieve at 29 lbs. Reducing Valve is factory set at 12 lbs. SEND FOR CATALOG CONTAINING COMPLETE INFORMATION AND ENGINEERING DATA YULA CORPORATION (formerly) Yula Water Heaters Inc.--Established 1926. 330 Bryant Avenue, New York 59, New York Designers and Manufacturers of Heat Transfer Equipment Member Fuel Oil and Water Heater Manufacturers Association 393 "YULATOM" FUEL OIL PROTECTION HEATER.'* Type "YA", approved by the Board of Standards and Appeals, City of New York-Cal. No. 678-57-SA. Here is a truly low cost, light weight, easy to install below water line oil heater. Due to its counterflow operation the exit oil can be delivered at high temperatures. Should a leak occur it is impossible for oil to get into Boiler or Piping. Made by the designer of the famous "Yulatrol" Oil Heater, so you know it is good. OIL TANK SUCTION HEATER--used to lower the viscosity of oil in bulk storage tanks to facilitate pumping. Only oil being drawn off is heated making it unnecessary to heat entire tank. "U" TUBE CONVERTOR--used in hot water heating systems where steam is passed through the shell while circulated water passes through the tubes. "U"- Tube construction allows for expansion of the tubes due to great temperature variations. FULL FLOATING HEAD EXCHANGER--used where straight tube construction is desirable affording easy access and cleaning of interior chambers while allowing for expansion of tube bundle. YULA THERMOSTATIC MIXING VALVE Automatically mixes hot and cold water and other DRY EXPANSION TYPE FREON COOLER The Yula Dry Expansion Freon Water Cooler is for use in air conditioning, refrigerating, industrial and fluids. Delivers mixture at any pre-determined con stant temperature. Sizes % in. through 3 in. Special calibrations are possible. process cooling, using water and other fluids. The , refrigerant passes through the tube side and is va porized. The fluid being cooled passes through the shell side which is bafP.ed. The carefully designed tube arrangement in these coolers provides high thermal efficiency and little pressure loss. Sound engineering has assured a positive oil return with the refrigerant in these units. Heat transfer and turbulent flow is as sured. Special Features: Liquid expansion thermostat gives uniform power at all points of the range with positive, gentle throttling action. The disc controlling the ports has two seats on a 35 deg angle; precluding freezing. Seat is in one part. Castings are heavy bronze. Close temperature regulation is obtained because valve is extremely sensitive. Seat spring is made of durable, corrosion resistant stainless steeL Complete shut-off on hot and cold water port in "non-draw" periods.
