Radiator Traps--Equipped with the famous Marsh phosphor bronze diaphragm charged with voliatile fluid. Extremely rugged, but so sensitive it closes tight on steam and opens instantly to pass condensate and air at only a few degrees below closing tempera ture. Highly efficient on pressures from below atmospheric up to 25 psi Other traps available for pressures up to 125 psi. Pressure Gauges and Dial Thermometers--The respected Marsh line covers every requirement for pressure, compound, alti tude gauges, ther-allimeters and dial thermometers. Marsh instru ments are the product of nearly a century of experience. i ranges and case styles for all needs. Radiator Trap and Pack- less Valve available in full range of sizes and patterns. Adjustable ori fice valves are availshie. Packless Radiator Valves--for hot water or steam, maximum water pressure 125 psi. Mechanical seal eliminates packing of any kind. New R-105 scries enables you to adjust orifice with twist of screwdriver to balance either steam or hot water system. Float and Thermostatic Traps--De signed for complete removal of air and con densate from steam mains, branches and risen. Condensate discharged through float operated.valve at bottom; air through vent in top. Wide range of pressure and capacity ratings. One of the many float and thermo static traps is illustrated. Line also includes Boat traps. Inverted Bucket Traps--Marsh quality and performance in a trap for applications where the inverted bucket type is indicated. Marsh Float and Hierinostalic Trap. Air Vents--Automatically remove air and gasses from tanks, coils or piping, liqnid pump systems, and other similar applica tions. Float holds valve tightly closed when system is filled. Opens only when air accum ulates. Has vacuum check which prevents return of air. Type illustrated is for working pressures up to 12S psi. Other types, includ ing float and thermostatic types, for low Marsh Inverted Bucket Trap. Solenoid Valves--in the "Master-mite" line may be had as either direct-acting con duit or grommet types. There are two port sizes: and NPT. Wide range of volt ages: 12, 24, 115, 208, 230 and 460 V, a-c. Pressures from vacuum to 540 psi. Orifice vary. Type 16 offers four: 3/64** through 3/32*. Type 26 has ten: 3/64* through Type 36 has eight body orifices, 3/64* through 5/32* and four top orifices, 3/64* through 3/32*. Many are Underwrit ers* approved as safety valve. Other Marsh solenoids, both direct-acting and pilot-oper ated, cover wide range of needs. Marsh No. 50 Air Vent "Master-mite" Solenoid Valve Conduit type Refrigeration Valves--Type 56 pressureactuated regulating valves shown here are adjustable for both Refrigerant 12 and 22-- from 60 to 270 psi. Though compact, they have ample capacity for wide range of ap plications. Other Marsh water regulating valves are both temperature and pressure, actuated. Piping and Duct Thermometers--For piping, air ducts, vessels, kilos, ovens, etc. Unbreakable with greater reading accuracy than glass tube thermometers. Line of 4 types, 7 ranges, 72 combinations. Big, legi ble 3%* and 4%* dials easily tilted or tamed to best reading angle. Specify di rect mount or distant reading. Separable sockets for easy installation. Extension necks for insulated piping or ducts. Long stems in duct* types put temperature-sensi tive section where it most be for accurate indication. Type 56 Water Regulator Marsh Piping Thermometer Bimetal Thermometers--Marsh Master Therm Bimetals are accurate to 1% of range. Available with Conoweld, Rad-Easy dial and Recalibrator. Back or bottom con nection. Seamless steel stems 2%*, 4*, 6*, 9*. 12*, 15*. 18* and 24*. Dial sizes 2*, 3*. 5* or 6%*. Adj'ostable Master Therms with SVs" or 6H' dials only.

NEW JERSEY 33 PACKAGED AUTOMATIC GAS HEATING PLANTS Providing Space or Volume Water Heating for Residential, Commercial and Industrial Uses <5,000 BTU/hr to 3,600,000 BTU/hr INPUT RATINGS HWQJhFrm HTDROTHERM boilers arc of all cast iron construction and arc exclusively designed for gas. The patented ab sorption unit, composed of deep-rib horizontal sections connected in zigzag, permits maximum heat transfer in min imum space with small water content, M*ai n-in vita HumM afcth Jacket: 4M lb*. *' X SI' X 38V4' This "true" gas design results in low fuel consumption, quick heat response, uniform heat transfer, self cleaning flue passages, and smalt installation space. HyDROTHERM boil ers are A-G-A.-a p proved for ad gases and are factory assembled and wired with the finest safety and gas controls, ready for quick installation. Boiler and controls are enclosed in an attractively finished insulated steel jacket MULTI-TEMP, a new con cept in heavy duty gas-fired hot water heating, provides any desired capacity with a . multiple of HyDROTHERM units, each equipped with its own controls. True input modulation is accomplished oScj r'swSisos tb*. 85" x 32'x V by having the separate boiler units fired or cut out in response to a special Minneapolis Honeywell electronic step-control. This control receives its signal from indoor-outdoor resistance bulbs. If the temperature in the supply header exceeds the desired setting, it simply steps back until the signals received from outside and inside are in balance. In leu critical installations, boiler units can be controlled by aquestats with different settings in the return manifold. AH boilers are tested at 250# hydrostatic pressure and carry a 100# ASME rating which permits direct connection of boilers to" city water lines as required for volume water heating applications. MULTI-TEMP, being' composed of multiple units, ofTcn extra protection against service interruption. Each boiler unit ts shipped completely as sembled to simplify field installation.
