Systems & Products

Every Mechanical / HVAC system we engineer — and why it matters

Explore each system below. We've kept it plain: what it is, why it matters for your project, the standards we build to, and the approved makes we use — so you can decide exactly which systems to get a quote for.

Built to: ISHRAE / ASHRAE 62.1SMACNA ductingIS 659NBC 2016 Part 8BEE energy efficiency

Chilled-Water Plants (Chillers)

Air- and water-cooled chiller plants with primary/secondary pumping, cooling towers and BMS-integrated plant rooms, sized from a building heat-load study.

Why it matters

The chiller plant is the single biggest energy consumer in a large building. A right-sized, high-IPLV plant with VFD pumping cuts running cost 20–30% and holds temperature and humidity precisely — protecting comfort, process and product.

50–2,000+ TR capacity
Screw / scroll / centrifugal
IPLV-optimised, VFD pumping
BMS / IoT-ready controls

Approved makes & standards we use

Daikin Carrier Trane Blue Star York Voltas

Offices, malls, hospitals, hotels or factories needing >50 TR of central cooling.

VRF / VRV Systems

Variable-refrigerant-flow systems running multiple indoor units off one outdoor unit, with zoning and heat recovery — designed, piped and commissioned end to end.

Why it matters

VRF gives each zone independent control with no plant room and excellent part-load efficiency. Ideal where occupancy and loads vary by area and time, so you only cool what's in use.

2–60 HP outdoor units
Heat-pump & heat-recovery
Long-run refrigerant piping
Centralised / app controls

Approved makes & standards we use

Daikin Mitsubishi Electric Hitachi Toshiba LG Blue Star

Offices, showrooms, hotels and clinics that need zoned comfort without a chiller plant.

AHUs, FCUs & Air Distribution

Double-skin air-handling and fan-coil units with SMACNA-class GI/aluminium ducting, VAV/CAV terminals, diffusers, dampers and filtration.

Why it matters

Air distribution decides whether designed cooling actually reaches people. Leak-tested ducting and correct CFM/throw protect both energy efficiency and indoor air quality.

SMACNA-class ducting
VAV & airflow stations
G4–HEPA filtration

Ventilation, Pressurisation & Exhaust

Fresh-air systems, NBC staircase pressurisation, basement and car-park ventilation with CO sensing, kitchen/toilet exhaust and jet-fan systems.

Why it matters

Ventilation is a life-safety and statutory requirement, not an option. Correct stair pressurisation and car-park smoke management are checked at Fire-NOC and keep occupants safe.

Cleanroom & Process Cooling

ISO-class cleanroom air-conditioning, precision cooling and desiccant dehumidification for controlled environments.

Why it matters

Pharma, electronics, food and data facilities need tight temperature, humidity and particle control. Non-compliant environments fail GMP and quality audits — this is engineering you cannot retrofit cheaply.

ISO 5–8 cleanrooms
Precision ±1°C control
Desiccant dehumidification
GMP-compliant builds

Pharma, electronics, food-processing or data centres needing controlled environments.

TAB & Commissioning

Testing, Adjusting & Balancing of air and water systems, controls commissioning and documented performance validation at handover.

Why it matters

Without TAB, the efficiency and comfort you paid to design is never actually delivered. It is also mandatory for green-building ratings and a clean handover.

NEBB/AABC-style TAB
Air & water balancing
Point-to-point controls check
Green-rating documentation

Any HVAC handover, green-building certification or an under-performing existing system.

FAQ

Mechanical / HVAC — frequently asked questions

How do you size an HVAC system for a building in India?

We run a full heat-load study (ISHRAE/ASHRAE 62.1) accounting for area, occupancy, glazing, orientation, equipment heat and the local climate zone, then select the right system — VRF, ductable or chilled-water plant. You can get a quick estimate from our free AC tonnage calculator, but the final design always comes from an engineered heat-load survey.

Should I choose VRF or a chilled-water (chiller) plant?

Use VRF for zoned comfort in offices, showrooms, hotels and clinics where loads vary by area and you want no plant room. Choose a chilled-water plant above roughly 50 TR of central cooling — malls, hospitals, hotels and factories — where a high-IPLV plant with VFD pumping cuts running cost 20–30%. We size both from your actual load and tell you which pays back faster.

Do you provide AMC and testing & balancing (TAB) after installation?

Yes. We commission every system with Testing, Adjusting & Balancing (TAB), hand over O&M manuals and as-builts, and offer annual maintenance contracts with 24/7 support so the system keeps performing.

Which cities and project types do you cover for HVAC?

We design and execute HVAC across 18+ Indian states for offices, IT parks, factories, cleanrooms, hospitals, data centres, hotels and warehouses, with a corporate office in Noida (Delhi NCR) and registered head office in Ludhiana.
