4Loop Automation engineers control systems, energy monitoring and the software on top — PLC, SCADA, steam and EMS — for plants across Pakistan and clients abroad. The engineers who design it are the ones who commission it.
Controls, energy systems and the software on top — the disciplines a plant usually has to split across separate vendors.
Most losses are quiet — steam nobody meters, lines drawing power between shifts, machines running at 80% and reporting 100. The work we do makes those losses visible and owned: controls that run the plant, metering that tells the truth, software that puts the right number in front of the right person every morning.
EMS and steam systems for textile, chemical and energy companies — generation and consumption metered, balanced and reported.
New PLC and SCADA builds, retrofits on running plants, and rescue work on systems left behind undocumented.
Dashboards, automated reporting and integrations — our own code, on top of the controls underneath.
On site across Pakistan · remote for international clients.
We work where our delivered projects live. Each sector comes with the systems we build most and the engineering it tends to need.
Everything in writing, a defects period honoured after sign-off. Here are the first three phases — the full method is on the next page.
You tell us what's broken, what's missing, or what you're weighing up. We listen, ask the awkward questions, and tell you inside one call whether we're the right firm. If we're not, we'll say so — and where we can, we'll point you somewhere useful.
An engineer on the floor with PPE, a notebook, and a camera. We walk every panel and instrument relevant to the scope, photograph nameplates, mark up P&IDs, and interview the people who actually run the equipment. The report is yours either way.
Functional design specification, control narratives, I/O lists and schematics. Reviewed with your team in plain English before code is written or wire pulled. Two formal reviews. Comments tracked, addressed and signed off in writing.
