Environmental testing lab · Navi Mumbai
Measured proof that your data centre air, surfaces and water are within spec.
Colo Enviro Labs tests particle cleanliness, gaseous corrosion, indoor air quality, water and thermal performance for data centres, cleanrooms and critical facilities. You get readings you can defend in an audit, a customer review or a warranty claim.
Lab at Goodwill Bizhub, MIDC Pawne, next to IKEA Turbhe, Navi Mumbai
What we test
Five test families, built around how data centres actually fail
Contamination damage builds slowly. Zinc whiskers, sulfide films on silver, dust that turns conductive at high humidity and scale in cooling towers rarely raise an alarm until hardware fails. Each service below targets one of those failure routes.
Particle count & cleanroom classification
Airborne particle counts at 0.3 to 10 µm, sample locations per ISO 14644-1:2015 Table A.1, class certificate for data halls, cleanrooms and pre-IST handover.
Particle testing → ANSI/ISA-71.04-2013Gaseous corrosion & reactivity monitoring
30-day copper and silver coupons at intake, supply and return air. Results give G1 to GX severity and point to the gas family causing it.
Corrosion testing → ISHRAE 10001 · ASHRAE 62.1Indoor air quality (IAQ)
CO₂, CO, PM2.5, PM10, TVOC, formaldehyde, temperature and humidity in NOCs, offices and control rooms, with ventilation advice.
IAQ testing → IS 10500 · ISO 11731Water, cooling tower & Legionella
Potable, cooling tower, chilled water, humidifier feed, STP outlet, fire water and liquid cooling fluid. Chemistry and microbiology done in-house.
Water testing → ASHRAE · NFPA 70BThermal, airflow & pressure mapping
Rack inlet mapping at three heights, tile airflow, room differential pressure, IR thermography of electrical panels, lux and noise.

Lab & equipment →Why it matters in Mumbai and Navi Mumbai
Local air is harder on electronics than most design briefs assume
Navi Mumbai's data centre belt sits beside the Thane-Belapur and Taloja industrial areas, the Thane creek and the Arabian Sea. That puts three things into the air your fresh-air units pull in: sulfur compounds from industry and diesel traffic, chlorides carried on sea air, and fine dust from construction that never seems to stop.
Since the move to lead-free (RoHS) boards, silver and copper on circuit boards react with sulfur to form creep corrosion that can short components. The monsoon then lifts indoor humidity, and dust that was harmless at 40% RH starts to absorb moisture and conduct.
None of this shows up on a BMS screen. It shows up as unexplained hardware failures 18 months later. Periodic testing is how you see it early and fix the filtration, pressurisation or cleaning schedule before it costs you a server.
| Risk | What we measure | Typical fix |
|---|---|---|
| Sulfide and chloride films | Cu and Ag coupon film thickness | Chemical filtration, sealing intakes |
| Conductive or hygroscopic dust | Particle counts, gravimetric dust | Filter upgrade, deep cleaning |
| Dust entering from corridors | Room differential pressure | Positive pressure, door seals |
| Hot spots and recirculation | Rack inlet temperature at 3 heights | Blanking panels, tile layout |
| Scale, corrosion, Legionella | Water chemistry and culture | Dosing correction, disinfection |
How an engagement runs
From your first call to a report your auditor accepts
Scope
You share drawings, room areas and the limits in your SLA or design basis. We confirm the standard and occupancy state.
Sampling plan
We fix the number and position of test points, sample volumes and timings, and send a method statement for your permit.
Site work
Calibrated instruments, logged on site with location IDs. Water and coupon samples are sealed and kept under chain of custody.
Lab analysis
Samples are analysed at our Navi Mumbai lab. Field data is checked against instrument calibration and blanks.
Report & review
Raw data, floor plan with points, pass or fail per location, likely causes and corrective actions. We walk your team through it.
Standards we test against
Your limit, your standard, stated on every report
We do not invent pass marks. Each report names the clause and edition used, so results can be compared year on year.
Why teams trust the numbers
Reports an auditor can trace, line by line
No marketing-grade “all clear”. Every figure on a CEL report ties back to an instrument, a method and a limit you chose.
Quality system, NABL in progress
Built to ISO/IEC 17025, with NABL accreditation under way. Until the scope is granted we say so plainly and our reports carry no NABL mark.
Calibrated, traceable instruments
Each instrument’s serial number and calibration due date is printed on your report, traceable to national standards. Past-due instruments are tagged out of service.
Raw readings, not just a verdict
Every report gives raw readings, sample locations, the method, the clause and the measurement uncertainty — so your team or auditor can re-check each number.
Independent of the cleaning crew
Testing is most useful when it is not done by whoever cleaned or built the space. We report raw counts and locations even when the site was cleaned by our group company.
Chain of custody & field blanks
Coupons and water samples carry a chain of custody from site to bench, with field blanks and duplicates on each batch.
