Condensators For returning water of condensation to boiler from open return line systems in dependently of boiler pressure, without change in operating conditions, air binding, or admitting steam to return side. Simple in construction, but positive in operation. All working parts are of best bronze metal. For use on Unit Heaters, also drips from supply mains and risers and on returns from water heaters and indirect stacks. Float-controlled Drip Type valve governs discharge of water; thermostatically-controlled valve allows passage of all air but prevents passage of steam. Made with % in., 1 in. and \lA in. tappings. Capacities 200 lb to 1200 lb of water per hour at 2 lb pressure differential. Combination float and ther mostatic traps with an air and water capacity large enough to take care of the condensation Heavy Daip Type from the largest vento stacks, dry kiln coils, hot water heaters and other units condensing large quantities of steam at low pressures. Made in sizes from 1 in. to 2 in. Ca pacities to 14,000 lb of water per hour at 2 lb pressure differential. 1014 Specialties, Heating GUNNELL COMPANY., Heating, Industrial and Power Plant Piping, Fittings, Hangers, .

National Distributors of Thermoflex Traps and Heating Specialties For data on other Grinnell Products, see pages 919-921 Thermoflex Specialties Thermoflex High Pressure Traps The heart of all Thermoflex Traps is the Hydron Bellows. The Hydron Bellows is formed under hydraulic pressure. This powerful internal pressure locates any weakness of any nature in the tubing. Such hydraulic pres sure is many times more severe than any pressure the Trap will ever be called upon to control. Every Thermoflex Trap, there fore, is practically indestructible. Thermoflex Traps have an exceptionally large orifice. This large orifice combined with high lift, insures fast action and freedom from clogging. We supply Thermoflex Traps guaran teed for steam pressures up to 25 lb. and to 125 lb. Complete information and details of typical installations will, be gladly sent on your request. Ask for Catalogue on Thermoflex Heating Specialties. Valves, Traps, Gauges, Etc. The Thermoflex line includes: Radiator Traps, Offset Traps, Blast Traps, Drip Traps, High Pressure Traps, Vent Traps, High-grade Packless Inlet Valves, and the Thermoflex Alternator, Thermoflex Com pound Gauge, Thermoflex Damper Regu lator. No. 12 Thermoflex Radiator Trap The No. 100A Thermoflex Trap is guar anteed . for steam pressures from 25-125 lb. Must not be used where the steam temperature exceeds 400 F. For use with all types of process work, Laundry Machinery, Kitchen Equipment, Hospital Sterilizers, Vulcanizers, Dry Kilns, Unit Heaters, Street Steam Service/ etc., in fact any place that a trap is desired for service at the above pressures. Small, compact and inexpensive in com parison to the usual float or bucket trap. Extra heavy body. Renewable nickel steel seat and disc. Bellows made from special bronze tubing and encased in brass sleeve to prevent distortion due to pressure. Regularly furnished without unions, plain nickel finish. Can be furnished with unions, polished nickel or chromium plated at extra cost. No. 4 Thermoflex Drip Traps The full eight-fold Thermoflex-Hydron Bellows is the best bellows ever made. Because of the Hydron-forming process every bellows is absolutely perfect. Body is heavy bronze construction throughout. Fully nickel-plated with highly polished' trimmings. The No. 12 is made in angle and in' corner patterns, with in. inlet and }A in. outlet tappings. The inlet neck is double thick to allow for expansion strains. Guaranteed for steam pressures up to 25 lb. Used for dripping mains, risers, coils and unit heaters. Cast-iron body, bronze cap and inserted renewable bronze seat, angle pattern only, without unions. Can be used for any general purpose where a finished, nickel-plated trap is not necesv sary, and at a lower cost. Guaranteed for steam pressures up to 25 lb. See also Pages 919-921 1015
