HVAC experts

HVAC is very rarely a one-size-fits-all game

Whether you’re implementing a new system, managing a building, or optimising HVAC performance, all kinds of equipment, products and expertise are needed to make the system work within the context of your building or facility. Couple that with the complications involved in the HVAC lifecycle, and finding a strategic partner that can help you every step of the way becomes an imperative.

We truly understand HVAC systems. In fact, we provide some of the most robust HVAC systems, parts and controls on the market today. But we don’t just sell products — we also offer the expertise, services and strategic insight to make them work within your current system, optimising your building’s performance and lowering your overall costs.

In-house design management

Our own design team — no third-party guesswork

We have in-house designing facilities to cater to the specific needs of our customers. Our team of experienced engineers, supervisors and technicians performs project and service activities across India as well as abroad, equipped with current technology, equipment and machinery.

  • Drawing work in AutoCADShop drawings, layouts and air & water flow schematics released for site work.
  • Design & load calculationsCooling loads run on software, with psychrometric analysis for critical areas.
  • Selection of fans and cooling coilsEquipment rated and selected against the approved technical specification.
  • Internal quality check listsTrade-wise check lists for ducting, piping and equipment installation, used with approved drawings to inspect completed work.

Method statement

How an HVAC project runs with us

The same four-stage discipline applies whether we are fitting out a new facility or retro-fitting a live one.

01

Design validation

We study your requirement, design intent and technical specification, then visit site to collect drawings and design inputs before any equipment is selected.

  • Cooling load and air flow calculations for each control zone
  • Psychrometric analysis, reheat figures and apparatus dew point selection
  • Verification of pumping head, fan static pressure, electrical load and filtration need
  • Shop and layout drawings coordinated with architects and other utilities
02

Procurement & coordination

Purchase orders are placed against approved drawings, with material tracked and vendors coordinated against the agreed delivery schedule.

  • Internal material request raised from released drawings
  • Material chasing and follow-up against the project bar chart
  • Inspection coordinated at the manufacturer’s works
  • Vendor data and drawings collected and filed
03

Site execution

A project manager and site engineer lead supervisors and associates across every trade, with a separate team held back for commissioning.

  • Sheet metal ducting, thermal and acoustic insulation
  • Piping, equipment installation and instrumentation
  • Electrical work and panel terminations
  • Second team dedicated to dry run, commissioning and balancing
04

Commissioning, testing & handover

Nothing is handed over until it has been proven against the design parameters it was engineered to meet.

  • Megger test on panels, cables, motors and earthing continuity
  • Panel energising and dry run for correct rotation
  • Air and water balancing across the system
  • Validation against design parameters, handover documents and as-built drawings

Why choose us

Why we’re the right choice for your facility

We have never compromised on the quality of the work or the service provided to the customer, and we believe in keeping customers informed at every stage.

Customised engineering solutions

Every facility is different. Our in-house team runs the load calculations and equipment selection against your building’s exact requirements — not a catalogue default.

Quality & safety standards

We follow industry best practice and safety regulations, with internal check lists for ducting, piping and equipment installation on every site.

Timely project completion

A detailed activity bar chart is prepared per project. Critical hold points are identified at the outset and remedial measures taken on items behind schedule.

Transparent pricing

Clear, itemised quotations and detailed project planning — so facility managers can budget with confidence and without hidden costs.

Have a drawing, a tender or a site problem?

Send us the scope. Our engineers will review the requirement, run the calculations and come back with an itemised proposal — no obligation.
