BFI offers tubes of diameter 3/8, 1/2″ and 5/8″. Tubes are smooth and seamless manufactured to ASTM specification with strict quality control. Tubes are available with smooth internal surface or internally enhanced surface to achieve high heat transfer. Tubes are mechanically expanded into fin collars to maximize heat transfer.
Fins are aluminum and are die formed plate type. Various types of fin surfaces like sine wave, louvered or raised lance are available to maximize heat transfer with minimal air friction. Optional materials include copper or pre-coated aluminum with corrosion resistant coating.
Hair Pin Bending
Automatic and semi automatic machines are used to bend the copper tubes in different sizes. Return bends are made of copper tube (3/8″, 1/2″, 5/8″) using automatic machine which are sized to provide smooth flow with minimum pressure drop.
Headers are designed to reduce potential for leaks and provide connection locations that allow draining or venting of coils. Headers are sized to achieve low pressure drop and proper flow distribution.
BFI uses automatic brazing machine and our qualified staff manually welds the larger units.
Vertical expansion machine is used for smaller condensers and for the larger ones horizontal expansion is used.
Wire condensers are manufactured using fully automatic machines.
