01
Air handling and filtration
AHUs with the pre-filtration and terminal HEPA arrangement the room class requires, sized for the air changes rather than for the cooling load alone.

Controlled environments
Filtered air, controlled room pressure, and temperature and humidity held inside a band — with the test results and as-built records an auditor will ask for.
A clean room is a documentation exercise as much as an engineering one. What is installed has to match what is on paper, and it has to be demonstrable on the day someone comes to validate it.
We build the air handling with terminal filtration at the room, set the pressure cascade so air always moves from the cleaner side to the less clean side, and seal the ductwork to suit the class of the room rather than to a general standard.
Handover includes the filter certificates, the test readings and a drawing set that matches what is actually above the ceiling — not the version from before the site changed.
Where this applies
Pharmaceutical manufacturing, analytical and bio laboratories, medical device production, hospital clean areas, and electronics assembly.

Scope
This is what goes into the quote. If something on your job is not on this list, it will be written in rather than assumed.
01
AHUs with the pre-filtration and terminal HEPA arrangement the room class requires, sized for the air changes rather than for the cooling load alone.
02
Differentials set and proved between rooms, airlocks and corridors, so the cascade holds when doors are actually being used.
03
Close control where the process needs it, with plant that modulates rather than cycling hard against the setpoint.
04
Test readings, filter certificates and as-built drawings compiled for handover, and our engineers available on the day of validation.
Common questions
Our scope is the air side — AHUs, ducting, filtration, pressure control and commissioning. We work alongside the panel and flooring contractors and will coordinate the sequence with them.
Yes, and most of ours are. It is a matter of screening the work area, controlling dust, and doing the noisy and dirty parts outside operating hours.
Filter checks and changes on schedule, differentials verified, and the AHU serviced properly. The pressure cascade is the thing that quietly drifts, so it gets checked at every visit.
We provide the engineering records — test readings, filter certificates, as-builts — which is what your validation team or external agency will work from.
Send us the drawings, the tonnage, or just a photo of the plant room. We will come out, measure up and give you a written quote — no charge for the visit anywhere in Chennai.
