Factory Fabricated Duct

In today’s times conventional site fabricated ductwork is dying out and factory fabricated ductwork is gaining popularity at a very fast pace. In a striking departure from conventional ductwork at site, we at ZECO make ducts on numerically automated machines.

Factory Fabricated Duct

As the name suggests this duct work is made in the factory as opposed to the project site. The benefits of pre fabricated duct over site fabricated are:

  • Low lead time leading to faster project completion
  • Low leakage leading to lower energy loss.
  • Ducts are made from G.I.coils instead of sheets.

Thus the duct is aligned properly after installation while the ducts made out of sheets will be out of alignment as the reference point is the corner of the sheet which itself is not at the right angle. The straight ducts are made on Autofolder, which aligns, makes stiffening braces, notches, and bends, and cuts the duct to the size all in a sequence as data is fed into the machine directly from the drawing.

  • With G.I. Coils we have consistency in the quality of the material, while in sheets we do not know if the entire lot is of the same quality as there is a lot of seconds material available in the market which cannot be differentiated by the naked eye.
  • The elbows, offsets, profiles, tapers, etc are made on a machine called plasma profile cutter.
  • The male parts of the profile are made on a machine called flanger and not by hand thus losing consistency.
  • The LAPAT (curved side) of the elbow is made on the rolling machine and not by hand again. The Pittsburgh lock is made on the Roll-former.
  • As the machines are all CNC automated we provide a detailed computer-generated packing list and area summary with each duct numbered.
  • We at ZECO can offer pre fabricated ductwork to meet any standards, IS, SMACNA, DW144 or even a standard created by customer/ consultant.

NOTE: We also provide spiral ducting in:

  • Elliptical shape
  • Oval Shape

Why ?  -Factory Fabricated Ducts

The benefits of Factory fabricated ducts over the conventional site fabricated ducts are as follows:

  • The benefit of factory fabricated ducting is that ducts are made from GI coils instead of sheets. Thus the duct is aligned properly after installation while the duct made out of sheets will be out of alignment as the reference point is the corners of the sheet which itself is not at right angle. The straight ducts are made on AUTO FOLDER, which aligns, makes stiffening braces,notches and bends and cuts the cut to the size all in one attempt.
  • With the G.I. coils we have consistency in the quality of material, while in sheets we do not know if the entire lot is of the same quality as there is a lot of seconds material available in market which not be differentiated by naked eyes.
  • The straight ducts are made on AUTOFOLDER, which aligns, makes stiffening braces, notches, bends and cuts the duct to the size all in a sequence as the data is feed into the machines directly from the drawing.
  • The elbows, offsets, profiles, tapers etc are made on a machine called
    PLASMA PROFILE CUTTER.
  • The male parts of the profile etc are made on a machine called FLANGER and not by hand thus loosing consistency.
  • The Lapat (Curved Side) of the elbow is made on the rolling machine and not by hand again.
  • The Pittsburgh lock is made on the LOCK FORMER.
  • The sealant for high-pressure ducts is injected in the Pittsburgh lock by
    the machine in the longitudinal joints and not latter by silicon tubes.
    As the machine are all CNC automated we provide a detailed computer generated packing list, Area Summary with each duct piece numbered.

Flanges

We at ZECO are into the manufacturing of three types of flanges, C & SS Cleat, TDC Flange & Slip-on Flanges.
