Industrial Automation

Control systems designed, built and commissioned in-house

From a single PLC retrofit to a plant-wide control system — we engineer the design, build the panels, write the code and stay on site through commissioning. On new plant, and on equipment that has been running for decades.

Platforms we work across: Siemens · Allen-Bradley · Delta · Schneider · Phoenix Contact · CG

Siemens PLC rack with I/O and safety modules

PLC & Controllers

Programming, integration and migration across Siemens, Allen-Bradley, Delta and Schneider platforms — new logic or taking over someone else’s.

HMI & SCADA

Operator screens, alarm management, trending and shift reporting — on your chosen platform, or on SENTIENT, our own in-house SCADA and IIoT platform.

VFD & Drives

Drive selection, parameterisation and commissioning for motors, conveyors, pumps, fans and furnace auxiliaries.

Instrumentation

Temperature, pressure, flow, level, proximity, laser and radar devices — supplied, installed, wired and calibrated.

Control Panels

PMCC, VFD and automation panels manufactured, wired and routine-tested in our own works against your single-line drawings.

System Integration

PLC, drives, instrumentation, safety and IIoT tied into one system that one team can support — including legacy equipment.

End to end solution, under one roof

Drawings, panel build, code and commissioning all come from the same team — so there is no gap between who designed it, who wired it and who answers the phone when it stops. One contract, one point of responsibility.

  1. 01

    Design & Engineering

    Control philosophy, I/O schedules, single-line and panel drawings agreed before anything is cut.

  2. 02

    Panel Manufacture

    Built, wired and routine-tested in-house, so the build and the logic come from the same team.

  3. 03

    Factory Acceptance Test

    Logic proven against simulated I/O with you present, before a panel leaves the works.

  4. 04

    Installation & Commissioning

    Loop checks, live tuning and operator handover on site — our engineers, not a subcontractor.

  5. 05

    Support & AMC

    Breakdown response, spares holding and planned maintenance under contract once you are running.

Retrofit & Migration

Ageing control systems, brought forward without losing a shift

An obsolete PLC or an unsupported drive should not become an unplanned shutdown. We reverse-engineer what is on the floor, map every loop to the new architecture, and stage the changeover around your production window.

  • Reverse-engineering of undocumented logic
  • Loop-by-loop verification against the old system
  • Changeover planned around your shutdown window
  • Operators trained before the old panel goes

Our own panel unit builds LT switchgear, AC and DC distribution boards, control & relay panels, PLC panels, starter panels and junction boxes.

Supply, Erection & Commissioning

Supply, installation, testing and commissioning of complete electrical projects, with erection supervision where you have your own contractor.

Protection & Relay Setting

Full protection co-ordination studies, ETAP-based power system modelling and numerical relay setting — then testing and calibration on site.

Retrofitting Existing Systems

Ageing electrical systems and panels brought back into service, with modified schematics and fresh coordination rather than a like-for-like swap.

Audits & Site Testing

Energy audits, feasibility reports, soil resistivity testing and transformer oil filtration — plus supply of electrical spares.

What a design package contains

Not a single-line diagram and a bill of materials. Every drawing and calculation a contractor, an inspector and your own maintenance team will ask for.

SENTIENT — our IIoT platform

One platform, from a single gateway to a plant-wide cluster

SENTIENT is our own industrial IoT and SCADA platform — device management, dashboards, alarms and a rule engine, with the local process control, PLC connectivity, reporting and recipe handling that plant work actually needs.

SENTIENT dashboards running on a control room desk overlooking a process plant

Built for plants, not for pilots

Most IoT platforms stop at charting telemetry. SENTIENT covers what a plant still needs once the dashboards look good.

Local SCADA, not just dashboards

Full process visualisation and operator control running on site — so the plant keeps running when the link to the cloud does not.

PLC communication that covers real plant

Talks to the controllers already on your floor, across the protocols industrial equipment actually speaks — not just MQTT and HTTP.

Reporting built for a shift log

Shift, batch and production reports generated straight from the historian, in the format your team already files.

Recipe management

Product recipes held centrally and pushed to the line, with version history and a record of the parameters each batch actually ran.

AI analytics as a first-class feature

Analytics is part of the platform rather than a bolt-on — anomaly detection and prediction against your own historian data.

A Rust core that scales both ways

The same platform runs on a low-power edge gateway or scales out to a high-availability cluster. One codebase, no separate edge product.

Written in Rust

Small enough for a gateway, built to cluster

The backend is a Rust application, so it runs in a fraction of the memory a JVM platform needs. That is what lets the same build sit on a low-power box beside the panel and also scale out across a cluster — no separate cut-down edge edition, no second system to learn.

Edge

Gateway on the wall

Low-power hardware next to the panel, holding its own data and screens when the network drops.

Site

One server on-premise

A plant-wide historian and SCADA on your own hardware, inside your own network.

Scale

High-availability cluster

Multiple sites into one system, cloud or on-premise, with redundancy where downtime costs real money.

Every deployment includes

Device management
Dashboards & visualisation
Alarms & events
Rule engine & automation
Trends & historian
Multi-tenant access control

CNC & Special Purpose Machines

The iron is fine. It is the controls that aged

A mechanically sound machine does not need replacing because its control is obsolete. We fit a new controller, drives, motors and operator panel to the machine you already own — and build special purpose machines from scratch where nothing off the shelf fits.

CNC lathe retrofitted with a new control, showing live axis positions

What we replace

  • CNC controller
  • Servo drives and motors
  • Encoders and position feedback
  • Spindle drive (VFD)
  • Operator panel and HMI
  • Electrical panel and wiring loom
  • Limit switches and machine I/O

What stays exactly as it is

  • Bed, column and castings
  • Spindle and bearings
  • Ball screws and guideways
  • Tool changer and turret
  • Hydraulics and coolant system
  • The machine’s original geometry

Spares that no longer exist

When a control is obsolete, one failed board can idle the machine for weeks. A current platform means parts are on a shelf, not on a forum.

Accuracy you already paid for

Castings, ball screws and guideways have decades of life left. Scrapping a mechanically sound machine throws away the part that took years to settle.

A control your programmers can use

Modern programming, networking and on-screen diagnostics — so the machine joins the rest of the shop instead of sitting apart from it.

Special Purpose Machines

When nothing off the shelf does the job

Some operations have no standard machine. We design and build one around the job — mechanics, drives, control and safety as a single package, sized to your cycle time and your floor space rather than a catalogue.

  • Built around one operation and its cycle time
  • Mechanical, electrical and control from one team
  • PLC, HMI and safety designed in, not added after
  • Documented and supported like any other machine

How a retrofit runs

A machine out of production is costing money, so the survey and the panel build happen before anything is stripped.

  1. 01

    Survey & feasibility

    Geometry, backlash, spindle and screw condition checked first — if the iron is not worth retrofitting we will say so.

  2. 02

    Control design

    Controller, drives and motors sized to the machine, with schematics and an I/O list before anything is ordered.

  3. 03

    Panel build

    The control panel is manufactured and wired in our own works, then tested before it reaches your floor.

  4. 04

    Installation

    Old controls stripped out, new gear fitted, axes aligned, tuned and backlash compensated.

  5. 05

    Commissioning & training

    Accuracy verified against test cuts, then your operators and maintenance team trained on the new control.

What we run ourselves

Design, build and commissioning are under one roof, which is why there is no gap between the drawing, the panel and the person on site.

Design office

Schematics, layouts, protection co-ordination and ETAP modelling — the drawings and calculations, not just the single line.

Panel manufacturing unit

Our own works building LT switchgear, distribution boards, control & relay panels, PLC panels and starter panels.

Site team

Erection, testing and commissioning carried out by our own engineers — including remote hydro sites in Ladakh and Arunachal.

Training & internship

We take on fresh graduates for summer and winter industrial training, so they get hands-on experience of testing, commissioning and maintenance rather than only the theory.
