Manufacturers of Air Cooled Fandaire Air Conditionert dt Condensers 1815 South Maybelle Tulsa, Oklahoma CHerry 2-9266 Beprutaiataa and DiOributm t Principal Citie FANDAIRE AIR COOLED CONDENSERS Available in through 80 ton capacity Conservatively rated, these condensers can be used on any application . . . either for new installation or as a replacement for outmoded equipment. While designed for outside installa tion, they work equally well inside. Their unique circular coil design delivers far greater operating efficiency than rectangu lar ' units. As standard equipment they incorporate many features normally sold as "extras." Fandaire condensers above are the 3 and 80 ton units FANDAIRE AIR COOLED AIR CONDITIONERS Available in through 10 ton capacity Fandaire air cooled air conditioners are very good for com mercial, residential and industrial installation. The unique circular coil construction delivers far greater operating efficiencyth&n rectangular units. They can easily be <r>TT>h;,,^ with existing heating systems. Fandaire advanced design in corporates, without extra charge, many features normally sold as "extras." Available with a full five year warranty. FANDAIRE FEATURES on both the air conditioning and condenser units GREATER FIN SURFACE EFFICIENCY The fins are helically formed around a heavy-wall eopper tube with a spacing of eight fins per inch to permit the free pas sage of lint and dust carrying air. This self-cleaning action helps maintain higher operating efficiency. The shoulder of eaceh on is firmm'ly swaged to the tube and to the ad"' jo`ini`*ng_ fin. 'N*o f`oreiggn matter or corrosion can form between the tube and the shoulder to cause loss of heat transfer even after years of ex posure to the elements. In addition, the shoulder provides a full 10Q percent con tact with the tube, guaranteeing the maximum amount of beat will be trans ferred to the fin. The fins are pyramidal in shape for sturdiness and to permit the best possible dissipation of the heat. TRUE COUNTER FLOW True counter flow is an action in which the hot refrigerant is gradually cooled by Sowing against (or counter to) the cooling medium. In other words, the refrigerant flows hot to cool, or counter to the cooling medium whicn flows cool to hot. In Fandaire units, the hot gas enters the condenser tubes at the inlet header inside the condenser and makes m five complete circles before leaving the p tube at toe outlet header. Since the cool air enters the condenser around the periphery of the coil and is pulled through the bank of tubes, the coolest gas is always in closest contact with the tubes carrying the coolest gas. This pro vides the best possible counterflow and assures a greater mean temperature at all times, giving a higher rate of heat transfer, lower condensing temperature mH a greater degree of sub-cooling. POSITIVE CONDENSATE DRAINAGE Each row or layer of tubes slopes down ward at a 30 deg angle. This means the tubes at the outlet header are lower than the tubes at the inlet header. This slope assures a better drainage of all* conden sate as fast as it forms on the tube wall. No pockets of compressor oil can form to act as an insulator between the hot gas and the air cooled tube walls. STRAIGHT THROUGH FLOW Each circuit consists of one continuous length of a single tube which completely eliminates ALL pressure drop caused by return bends. Laboratory tests have shown that up to 60 percent of the pres sure drop normally found in rectangular units is due to the short radius return bends necessary in their construction. Fandaire's long-sweeping, one-circuit construction approaches the almost non existent pressure drop of a single pass unit while retaining all the advantages of a five-pass unit. VERTICAL AIR DISCHARGE Vertical air discharge is part of the standard construction. -No air scoop or wind deflector is necessary. This vertical air discharge eliminates any tendency to re-circulate hot air and is a "must" in multiple installations. With Fandaire units there are no dead spots to be found on the face of the coil since the air is drawn around the circumference of the coil. Wind from any direction can be used, it is not necessary to face the units in the direction of the prevailing wind. HOUSING All Fandaire models are weatherproof. They are housed in attractive, corrosion resistant housings of a spun construction. Models up to 7H ton are made of alumi num alloy--all other models are gal vanized after construction for a durable, maintenance free finish. The air condi tioners are supplied with a two-piece, wrap-around skirt. Many other features, normally sold as "extras" on other units, are incorporated in the standard Fandaire design. These include legs, mount ing brackets, fan guards. MOTORS AND FANS Either direct drive or belt drive weather proof or totally enclosed, ball bearing, permanently lubricated motors are used on all Fandaire models. Fans are axial flow type and are constructed from plated, heavy-duty corrosion-resistant steel or aluminum.
