About us
Forty-plus years of building the plant before the plant exists.
Tri-Angle Simulation Pvt. Ltd. has done one thing since 1979: make it possible to learn a process plant without risking one.
§ 01Company overview
India’s first process simulation company, still doing the same thing.
Tri-Angle Simulation Pvt. Ltd. was founded in Mumbai in 1979. At the time, simulator-based training belonged to aviation, aerospace and nuclear power. The idea that a refinery board operator or a boiler engineer should also learn on a model first was, in India, new.
We built the country’s first process simulator at the Advanced Training Institute in Madras in 1983, and delivered India’s first digital computer simulator to Bharat Petroleum in 1985. Since then the work has covered crude and vacuum distillation, catalytic cracking, sulphur recovery, ammonia and urea, 210 MW and 500 MW thermal units, hydro sets, pulp and paper, and the unit operations taught in engineering laboratories.
The company remains engineering-led and family-run. Its simulation libraries — the front end and the back end both — were written in-house and are maintained by the people who wrote them.

What we are aiming at.
Vision
To be the preferred supplier of competitively priced, high-fidelity simulation software and training equipment for refineries, power plants, fertiliser plants and academic institutions.
Mission
- To be an innovative and consistently reliable supplier.
- To always display the best working standards and values in all we do.

- To be a company with which employees want to build a long-term career.
- To continuously improve our products, practices, technologies and services.
§ 04Engineering expertise
Six disciplines, one team.
A simulator is a process problem, a control problem and a software problem at the same time. All three are handled in-house.
- 01
Process engineering
First-principles dynamic modelling of distillation, cracking, reaction, heat transfer, separation and utility systems.
- 02
Power plant engineering
Boiler, turbine, generator, electrical and balance-of-plant systems, including FSSS, ATRS, co-ordinated master control and turbine stress evaluation.
- 03
Control & instrumentation
Loop design and tuning, interlock and trip logic, DCS emulation, SCADA supervision and PLC integration.
- 04
Software development
Real-time simulation engines, animated graphics, instructor tooling, cloud-native platforms and embedded firmware.
- 05
Hardware & fabrication
Instrumented lab-scale rigs and pilot plants, structural tanks and piping, control panels, electronic boards and embedded systems.
- 06
Applied AI/ML
Simulation automation, predictive analytics and personalised training environments for next-generation platforms.
§ 05Core values
How we prefer to work.
Engineering before marketing
A model either matches the plant data or it does not. We would rather spend the extra week tuning it than describe it well.
Built here
Our simulation libraries, model builder and graphics utilities are our own work. Nothing important is a black box we cannot open.
Safety is the point
Every simulator exists so that a mistake happens on a model instead of on running plant. That is the whole argument for this industry.
Long relationships
Several of our installations have been in service for over twenty years, maintained by the same company that built them.
§ 06What we do
The work, in six lines.
Operator Training Simulators
Dynamic plant models driving an emulated DCS or a one-to-one panel replica, with an instructor station that controls every session.
Dynamic model development
Custom first-principles models tuned to your equipment data, valve characteristics and five sets of operating data across the load range.
Lab-scale process trainers
Working PC-based control rigs — level, flow, cascade, pH, pressure, distillation, reactors — for teaching laboratories and training centres.
Hardware-in-loop testbeds
Real transmitters, controllers and final elements wired to a live mathematical model, for control-system testing and research platforms.
Operator & student training
On-site and classroom programmes running from three days to a week, delivered at plants, training centres and engineering colleges.
Commissioning & support
Site acceptance testing, model tuning against plant data, handover training, and long-term maintenance of the models we deliver.

§ 09Our commitment
Safety, quality, innovation, support.
Safety
Simulators exist to move error off live plant. Every design decision is measured against whether it makes the training more faithful to what the operator will actually face.
Quality
Models are tested in-house against every trip logic and interlock before they leave, then tested again on site with your engineers present.
Innovation
Continuous in-house R&D — currently cloud-hosted and mobile-accessible platforms, modular simulation environments, digital twins and AI-assisted training.
Customer support
Handover training, warranty support and model maintenance as the plant changes, for as long as the installation is in service.
§ 10Looking ahead
Where the work is heading
Four decades of Windows-based simulation platforms gave us models that plants trust. The next generation of that work is being rebuilt around how engineers now expect to reach software.
- Cloud-hosted platforms reachable from web, tablet and mobile
- Modular, API-ready simulation environments
- Real-time dashboards and training analytics
- AI/ML-assisted scenario generation and personalised training paths
- Subscription and rental options alongside outright purchase
- Digital twin development for ports, power plants and chemical plants
