Engineering heat.
Globally.
We design before we build. Three decades of engineering-first fired heaters — proprietary thermal simulation, CFD and FEA behind every design, and 230+ high-criticality revamps that restarted on time.
One material problem.
Owned end to end.
Design, build, restart, revamp, license — when heat is the hardest part of your process, we own every stage of it.
Fired Heater EPC
Full-spectrum design, fabrication, modularization and commissioning of fired heaters for refining and petrochemicals.

TECHNOLOGY LICENSING
When failure is not an option, refiners call us.
A refinery losing millions per day of downtime doesn't hire the lowest bidder. It hires the contractor who has restarted 230+ high-criticality units — on the date promised.

We don't just build technology.
We own it.
Rare for an Indian engineering company: proprietary process technology. We license complete LSTK Acetic Anhydride plants — performance-guaranteed end to end, from raw material to final product quality — built around our Ketene cracker.
Analysis first.
Steel second.
Our equipment performs because the engineering comes first — three decades of in-house thermal analysis, built to the standards the global industry runs on.
WinHeat®
Our proprietary thermal rating and simulation engine, in continuous development since the 1990s. The reason our heaters perform.
CFD & FEA
Flame-pattern CFD and structural FEA on every critical design — simulation outputs most competitors never publish.
Modular Construction
Shop-built, plug-and-play heater modules cut site labor by ~40% — engineered for global shipping and fast erection.
Standards & Approvals
Active API member, engaged with the fired heater standards community. ASME U+S · IBR · EIL-enlisted · ISO 9001 / 14001 / 45001.
One revamp.
Three wins.
A performance revamp of Chemplast Sanmar's EDC cracking furnace — re-engineered with WinHeat® and CFD, executed without schedule slip.
Built in India.
Building toward the world.
160 people across an engineering HQ and two manufacturing shops — with early international references and a registered US entity.
