TI Air Cooled Condensers are offered in 11 models with heat rejection capacity range of 29 to 2194 KBH, designed to accommodate a wide range of application in the A/C industry. Casing: Suitable heavy gauge galvanized steel sheets are used in the manufacture of casing panels and mounting chassis formed from heavy gauge steel sheets offer maximum rigidity. Coils: Condenser coils consist of seamless copper tubes mechanically expanded into die formed aluminum or copper fins with 8 to 12 FPI spacing. Coils are available in single and multi-circuits. Fans: Directly Driven axial fans, deliver the required air flow rate at minimum sound levels. All fans are equipped with fan guard for maximum protection. Fan operation sequencing is performed based on the liquid refrigerantâ??s pressure leaving the condenser. Motors Totally enclosed air cooled (air over body) electric motors equipped with permanently lubricated bearings, an IP-54 protection, winding insulation class of F plus thermal protection and B rise construction are mounted in vertical position. The motors are suitable for operation. Electrical Panel: Consists of a drip proof enclosing all electric components such as contactors, over load protections. Testing: Condenser coils are leak tested at 450 psig after production and the entire condenser unit is tested at 350 psig working pressure after production.
