Chiller and pump installation
Equipment set, aligned and connected, with vibration isolation and enough clear space around it to open a panel later.
Chilled water
Chilled water systems and HVAC plant in Chennai
For buildings big enough that refrigerant piping stops making sense: chillers, pumps, headers, air handling units and the plant room that has to be maintainable ten years from now.

- New & retrofit
Plant rooms usually grow by addition. A pump added here, a line re-routed there, two valves that no longer isolate anything. After a decade nobody can shut down half the system without shutting down all of it.
A good part of our chilled water work is putting that right — re-working headers so each section isolates on its own, labelling what is actually there, and giving the maintenance team room to stand where they need to stand.
On new plant we handle the equipment, pumps, pipework, insulation, air handling units and the water-side balancing, and we hand over a plant room that reads clearly to someone who was not there when it was built.
Where this applies
Hotels, hospitals, large institutional buildings, manufacturing plants, and any property already running a central plant that has become difficult to maintain.

Scope
What the work covers
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.
02
Headers, valving and isolation
Sections that can be isolated individually so a fault or a service does not take the whole building off cooling.
03
AHUs and air distribution
Air handling units installed, connected and commissioned, with filtration to suit the area they serve.
04
Water balancing and records
Flow set and recorded circuit by circuit, and a marked-up drawing that matches the pipework as installed.
Common questions
Questions we get asked
At what size does chilled water beat VRF?
There is no single number — it depends on the building shape, the riser space and how long the pipe runs get. As a rough guide, once you are past a few hundred tons across several floors, chilled water usually wins on both cost and maintainability.
Can you take over an existing plant room?
Yes. We will survey it first and give you a written condition report before quoting anything, so you know what you are inheriting and what it will cost to make it serviceable.
Do you do the AHU side as well as the plant?
Yes — plant room through to the air handling units, ducting and terminals. It is easier to commission a system when the same team is responsible for both ends of it.
How disruptive is a plant room retrofit?
It depends entirely on how much redundancy you have. Where there is none, we phase the work and provide temporary capacity for the critical areas. That gets agreed before the job starts, not during it.
Tell us what needs cooling.
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.
