JENKINS PRACTICAL PIPING LAYOUTS How to plan PIPING CONNECTIONS , FOR A NON-FREEZE COOLING TOWER The non-freeze cooling tower illustroted here la one of several types in use for hotels, institutions, supermarkets, and shopping centers where unin terrupted refrigeration is a rouml-.the-clock oper ating requirement. Tim type offers the advantage of a dependable supply of cooling water at low cost, and conforms with water conservation regu lations now in effect in many locations. Cooling lower and compressors must operate an the same schedule in any continuous refrigera tion system. The tower must perform its function even when the temperature is below freezing. For this reason, the water used in this system is stored in a vented or open tank located in a heated space, rother than in the conventional pan under the exposed tower. When freezing weather occurs, an anti-freezo solenoid valve, actuated by a temperuture-sensitive device, opens to drain all water from lines exposed to outside temperatures. Tlio automatic 3-way solenoid valve, also temperature actuated, permits the water to bypass the cooling tower under freezing conditions, or when It becomes too warm duo to fan failure or overload in the storage tank. Under the latter condition, the auto matic overheat dump valve would also open. The subsequent drop of the water level in the storage lank causes the float valve to open and admit city water to make up the deficiency. Thus, in an emergency, city water would he used for cooling. The Jenklna Solder End Valves reeom-^ mended for various control points in this system'-*^ ore made for use with Types K, L, and M copper tubing. Designed by Jenkins specialists, they have the extra durability that assures life-time econoiny and trouble-free performance even where valve usage is most severe. Their liberally dimen- '(* sioned body costings will withstand the heat of " soldering without danger of distortion or warp- *4 ing of seats. Consultation with accredited piping engineers ; ami contractors is recommended when plonnina any major piping installation. To savo time, to simplify planning, to get all the advantages of Jenkins specialized valve engineer- *..i ing experience, select all the valves you need from jj the'complete Jenkins line. It's your best auur- ^ once of lowest cost in the long run. Jenkins Bros^ V. 100 Pork Avc.. New York 17. Sold through lead- V,' ing Industrial Distributors everywhere.
