Manufacturing Process

Fin Press Line

Fining is done on state of the art American machines & can fin with Plain Aluminium, Pre-coated / Hydrophylic Aluminium & copper fins.

Tube Cutting [Straight cut to length]

Straight Cut to Length

Fully automatic American straight cut to length machine makes the LWC copper pipes to cut in desired lengths.

Hair Pin Bending

Hair Pin Bender

This American machine eliminates the use of return bend on one side of all coils for 3/8” OD & ½” OD tubes.

Sheet Metal – Casting Work

CNC Punching M/C

For all casing work i.e. Endplate, side-plate, Intermediate support plates , this Japanese machine makes sure it very much precise through CNC operation.

Expansion

Tube Expander

All coils are expanded using bullet expansion & for coils less than 1400 mm long, the vertical expander is used to ensure firm bonding between tube & fins.

Expansion

End Closing

Branching

This European machine ensures that Headers of coils are closed at ends using latest end-forming technology by eliminating the use of traditional end caps.

Header Assembly

This machine is used to assemble the feeder tubes with Header Pipes & also for assembling connectors with Header pipes.

Main Coil Assembly

Brazing

All coils are brazed either manually or on the automatic brazing machine using latest technology to make the process faster.

Testing

Leak Testing

All coils are leak tested with dry compressed air (equivalent to N2). Condenser coils are leak tested at 450 psi & evaporator coils are tested at 350 psi.

Anti-Corrosive Coating

Heresite

As per requirement coils are coated using spray technology for anti-corrosive coating such as Heresite – USA origin or Copon blue coating.

Packing

Every coil is packed by following stringent packing methods to ensure no damages happen during transit.
