DSIIDC Bawana and Narela — purpose-built plots with real process plant. Full instrumentation, calibration and packing machinery, supplied from Faridabad.
Most of Delhi's industrial estates grew up around whatever was already there. Bawana and Narela did not. They were laid out by DSIIDC as relocation and expansion sites, so the plots are larger, the roads are wider, and the units on them are doing heavier work than a Naraina or Wazirpur shed can accommodate.
That means real process plant. Injection moulding with heated barrels and chilled tool water. Rubber mixing and curing. Paint and resin batching with jacketed vessels. Steel fabrication with furnaces. Food and pharmaceutical intermediates with utilities that have to be documented.
The instrument list here looks much more like a Faridabad or Bhiwadi plant than like the rest of Delhi. Zone controllers, thermowells, level transmitters and proper control panels — not a single dial gauge on a compressor.
Moulding barrel zones drifting apart. A three or four zone barrel controlled by separate loops will drift if each zone is tuned once and never checked. Multi-zone controllers with independent auto-tune hold the profile; a mismatched set of single-loop controllers does not.
Chilled water and tool temperature. Moulding quality tracks tool temperature more closely than most shops realise. Sensors buried in the tool with a poor thermowell fit read slow and low, and the operator compensates by adjusting something else.
Batch vessel level and temperature in paint and resin. Solvent atmospheres and viscous, coating media. Ordinary level floats stick, and a plain Bourdon gauge blocks. Diaphragm seals and the right level technology are not a luxury here.
Furnace and curing oven thermocouples. Base metal thermocouples drift steadily at high temperature. On a furnace running every day, that drift becomes scrap before it becomes an alarm.
Multi-zone controllers with independent auto-tune, mineral insulated barrel and tool sensors, heat-cool control for chilled tool water, hydraulic circuit gauges.
High-temperature thermocouples, ramp-soak programmers that run the cure profile start to finish, steam gauges with siphons, panel annunciators.
Diaphragm seal gauges matched to the batch chemistry, level technology chosen for coating media, and certified instruments where the zone requires them.
Noble and base metal thermocouples with protection tubes, bar-stock thermowells, and multi-channel scanners that log every zone on one time base.
For plastics and moulding: multi-zone PID controllers with independent auto-tune, mineral insulated thermocouples and RTDs for barrels and tools, heat-cool controllers for chilled tool water, and pressure gauges on hydraulic circuits.
For rubber and curing: high-temperature thermocouples, ramp-soak programmers for cure profiles, steam pressure gauges with siphons, and panel annunciators.
For paint, resin and chemicals: diaphragm seal gauges with wetted materials matched to the batch, level transmitters and switches suited to coating media, flameproof instruments where the area classification calls for them, and control panels built to your scheme.
For steel fabrication and furnaces: noble metal and base metal thermocouples with protection tubes, multi-channel scanners, and thermowells built from bar stock rather than fabricated.
Plot sizes here allow machinery that Okhla or Mohan Cooperative cannot take. Fully automatic in-line strapping runs off a conveyor and needs three-phase power, and on a plant despatching continuously it pays for itself in labour within a year.
For plants running one or two carton sizes, a semi-automatic sealer is the sensible answer and costs a fraction of a random machine. Where the size changes constantly, the random sealer earns its price. We will tell you honestly which of the two your carton mix justifies rather than quoting the larger machine by default.
Box wrapping with top press, hydraulic pallet trucks and drum carriers complete the despatch bay. Consumables are quoted with the machine so the running cost is visible from the start.
In-line strapping off a conveyor for continuous despatch — three-phase, and it repays the labour within a year on steady volume.
Arch machines for variable volume, single-phase, no conveyor needed. Often the better buy, and we will say so rather than quote the bigger machine.
Semi-automatic where one or two carton sizes run; random where the size changes constantly and resetting by hand is costing you a person.
Box wrapping with top press for palletised despatch, hydraulic pallet trucks and drum carriers for the bay.
Building on a Bawana or Narela plot? Send the P&ID, the tag list, or the equipment schedule. We size the full instrument list, tell you where the design has specified something it does not need, and supply it with the certificates your consultant will ask for at handover. Loop checking and commissioning support are included.
Relocated a plant and now running it here? A great many units in Bawana moved from older estates, and instruments that survived a shift are often the first things to fail. We replace like-for-like against your existing tags, recalibrate what is still good, and say plainly what does not need touching.
Both are handled by the same engineers — there is no separate projects team that disappears after commissioning.
The packing and sealing machinery mentioned above has its own pages, written around the machine rather than the area. If that is the part you are working on, start there.
Strapping machinesAll packing & sealingYes. They are the far side of Delhi from our Faridabad works, so we plan the run rather than promising same-day. Stock items ordered before 4 PM normally reach you the next working day.
A multi-zone controller with independent auto-tune per zone. Each zone then tunes to its own real behaviour, which single-loop controllers set once and left alone will not do. It also saves panel cut-outs and wiring.
Yes. Solvent atmospheres and coating media need diaphragm seal gauges with the wetted material matched to the batch, level technology chosen for a coating liquid, and where the area is classified, flameproof instruments with a CCoE certificate supplied with the goods.
Yes, to your scheme — with the controllers, indicators, annunciators and interlocks specified, wired and tested before despatch, and as-built drawings handed over.
That is common work for us. Send the existing tag list and we will tell you what can be reused, what should be recalibrated and what is better replaced. Instruments that have been moved are the usual early failures.
It depends on cartons per shift, not plot size. On continuous despatch it repays the labour within a year; on variable volume a semi-automatic arch machine is the better buy. Tell us the peak-hour count and we will say which.
Yes — traceable certificates with as-found and as-left readings at each point, the reference standard and its certificate number, ambient conditions and measurement uncertainty.
Send a photograph of the nameplate, a tag list, or simply tell us the duty. Our engineer will size it and quote it.
