Because air is our drive & industry is our domain.
For over 25 years, we've been the engineering force behind Gujarat's most demanding industrial air systems — designed, fabricated, and maintained to perform precisely when and where they must.
In 1999, in the heart of Ahmedabad, a company called Vision Air Tech was founded on a straightforward belief: that the air inside an industrial facility matters just as much as the machinery within it. Too many projects treated HVAC as an afterthought — specified late, sourced cheaply, installed by whoever was available.
Vision Air Tech was the answer: a firm that treats HVAC as a discipline, not a commodity. Over two decades, that answer proved itself — project after project, industry after industry, across Gujarat and Western India.
In recognition of that growth, the company was reborn as Phalange Industries Pvt. Ltd. The name changed. The conviction did not. Today we're trusted not because of the loudest marketing, but because of the quietest metric in the industry — the clients who return for their next project, and the ones after that.
Over 25+ years, our engineering footprint has expanded across key industrial hubs — from GIDC Vatva, Naroda, and Changodar to Vadodara, Surat, Rajkot, and broader Western India. We have executed turnkey air control projects for pharmaceutical cleanrooms (cGMP / Schedule M), chemical processing, heavy manufacturing, dairy, food packaging, and commercial towers.
What sets us apart is our end-to-end vertical integration. With our own manufacturing facility in Ahmedabad, dedicated installation engineers, and in-house TAB balancing capabilities, we provide complete single-point accountability — eliminating vendor coordination friction and guaranteeing long-term system performance.
Every system is engineered to meet the specific operational demands of the environment it serves — not the easiest environment. Yours.
Efficiency is engineered in from day one, not bolted on. Systems that are cost-effective to own and operate over their full lifecycle.
Our technical recommendations are honest. If a solution isn't the right fit, we'll tell you — and propose what is.
We're built to be excellent at All the process — from the first technical conversation to the last scheduled maintenance visit, years down the line.
Structured technical engagement assessing your facility, heat load demands, and compliance landscape before drafting engineering proposals.
Complete MEP system designs reviewed by senior engineers — built for thermal efficiency, optimal static pressure, and constructability.
Every duct and fabricated component is made in our Ahmedabad facility — to exact drawing specs, by our fabricators, under strict internal QC.
Specialized trade teams supervised by experienced site engineers, guaranteeing precise installation across ducting, piping, and insulation.
ISO Class 5-8 clean room systems with modular puff panel partitions engineered strictly to Schedule M, cGMP, and WHO-GMP standards.

There are no handoffs between a design consultant, a fabrication contractor, and an installation agency. Every phase is owned, managed, and delivered by our team.
From first site assessment through commissioning and beyond — one team owns the outcome.
Every metre of ductwork is designed by our engineers and fabricated in our Ahmedabad facility.
We don't staff projects with generalist labour — every discipline has a dedicated, trained team.
Every product and system we work with has been selected, tested, and refined through application in demanding environments. We match the solution to the problem — not the other way around.

When you choose an HVAC partner, you're choosing how your facility performs — and how you feel about the decision two years from now.
Air engineering is our entire focus — not one line item on a broader MEP scope.
Every trade — duct, piping, fabrication, commissioning — has its own dedicated team.
We design, build, install, commission and maintain. If it underperforms, it's on us — and we fix it.
Our in-house fabrication facility gives us direct control over quality before it reaches site.
The ability to anticipate problems before they occur — across every major industrial sector.
Not an upgrade option — a default design principle in every project we deliver.
Every project follows a structured, stage-gated methodology that eliminates guesswork and manages risk — so what we commission performs on day one, and every day after.
We start with understanding, not selling.
Precision design before a component moves.
Transparent proposals, no hidden variables.
Built to our standards before reaching site.
Specialist teams, accountable management.
We don't sign off until it performs.
Our relationship doesn't end at commissioning. We provide planned maintenance through AMC programmes and responsive support for any operational issues that arise — from the team that built the system.
Decades of technical expertise, commercial leadership and strategic vision — the culture this company operates from.
At the centre of the company's technical journey since its founding as Vision Air Tech in 1999 — over two and a half decades in HVAC design, project execution and industrial air engineering. His philosophy: engineering outcomes are earned on-site, not promised in proposals.
