Heating Systems Heat Transfer Products RICHMOND ENGINEERING CO., INC. RECO HEAT EXCHANGERS 7th & Hospital Streets, Richmond, Va. RECO TANKS, INC. Holts Chapel Road--Greensboro, N . C. P. O. Box 147--Columbia, S. C. RECO HOT WATER STORAGE HEATERS Horizontal and vertical types. Designed for installations requiring large quanti ties of hot water at irregular intervals. Hot water reserve is held to meet peak demands. Steady recovery in low de mand periods keeps boiler load con stant. Removable heating elements are of seamless copper U-bend tubes. Shells available in variety of materials, coat ings and linings. Write for free catalog. RECO CONVERTORS A shell and tube heater of 2-pass design for use in forced circulation hot water heating systems. Fine for schools, fac: tories,hospitals, apartments, etc. Heat ing is by steam in shell, water in tubes. Removable heating elements are of seamless U-bend tubes to eliminate in ternal joints and expansion stresses. Write for free catalog. RECO INSTANTANEOUS HEATERS A shell and tube heater of multiple pass design for use where a continuous supply of hot water is desired and where the steam supply is adequate for peak loads. Live steam in shell used to heat water or other liquids. Can be connected to cir culate through RECO storage tanks. Write for full details. RECO HEAT RECLAIMERS (Pit Type) Good for reclaiming waste hot water solutions to pre-heat cool liquids. Hot waste water flows by gravity through pit and around submerged tube bundles. Incoming liquid in tubes absorbs heat. Complete, baffle-controlled counter flow gives excellent heat transfer and re covery. RECO HEAT RECLAIMERS (Closed Type) Serves same purpose as Pit Type^--Utilizes waste heat to pre-heat cool liquids. This reduces fuel consumption and op erating costs. Closed type Reclaimer convenient where space is tight. Waste water pumped through tubes arranged in senes. Incoming liquid circulates through shell.

Easy to install, available with steel or cast iron tanks. Three sizes for ratings up to 15,000 sq ft EDR, 20 psi. Rotary Type seals. Dual Voltage motors. Make-up water valve or float switch controlled. 8500Series: Heavy duty units with ped estal mounted steel tank for a wide range of jobs--2000 to 65,000 sq ft, up to 150 psi. Special units with larger tanks for package boilers. 8700 Series: With heavy cast iron tank for installation underground or in wet locations. 2000 to 20,000 sq ft, 20 .or 30 psi. Available with special tank sizes. Vacuum Pumps: Type V, 2500 and 5000 sq ft, 20 psi. Type S, 10,000 to 40,000 sq ft, 20 to 40 psi. SERIES 120-A THERMOTROLS Self-contained individual radiator tem perature controls for steam or hot water. Simple to install! Eliminate overheating, save fuel. Maintain even temperature for comfort and health. Sizes: % in., % in., 1 in. Body styles: Angle, Straightway, Corner. THERMOSTATIC TRAPS: Exceptional for keeping radiation free of air and con densate. Uses the "Sterlco Vacuum Ther mostat" which closes uniformly regard less of pressure variation. If damaged, the thermostat fails in the closed posi tion shutting off the radiation and giving positive indication that the trap needs attention. Trap maintenance greatly simplified. All traps equipped with re placeable seats. Four pressure ratings: 15, 65,100,125 psi. % in. L.P. angle body has smallest overall dimension for use on fin tube radiation. Popular 69B illustrated FLOAT and THERMOSTATIC TRAPS Used wherever it is desired to prevent flow of steam, but to permit passage of air and water ... on unit heaters, large radiators and convectors, water heaters, steam main drips and other types of equipment where steam is used. Com pact, rugged, easy to service. "Vacuum thermostat" vents air, float valve has plenty of capacity for large amounts of condensate. Sizesin.,! in., in., 1% in., 2 in. Max. pressures: 15, 100 psi. Also "V" Strainers, Radiator Valves, Vacuum Pumps, Boiler Return Traps. SERIES 150-E TEMPERATURE CON TROL VALVE Self-powered modulating control valveapplicable to any process involving heat ing or cooling by means of water, oil, steam or other fluids. Monel thermostatic and seal bellows, armored capillary tube, stainless steel trim. Mounts any position. Sizes: % in., ^ in., 1 in. Also 117A Series--1J4 in. to 2 in. Heating only. 407
