About · Quality, certifications & sustainability
Every unit tested.
Every claim certified.
The paperwork buyers ask for and the laboratory behind it — NABL, ISO 9001, ISO 14001, BIS — plus what responsible manufacturing means on an Ezentech line.
Quality system
The paperwork buyers ask for,
and the lab behind it.
Four credentials, what each one covers, and why it matters to the person signing the purchase order.
Credentials
04 credentials
- NABL-accredited psychrometric laboratory
- Accredited competence of Ezentech's own laboratory to measure air-conditioner performance — cooling capacity, power input, ISEER — under controlled temperature and humidity.
Why it matters: The rated figures on the sheet come from an accredited, audited method, not a supplier's estimate.
- ISO 9001 quality management system
- Documented processes, in-line inspection, corrective action and internal audit across the plants.
Why it matters: A repeatable process behind every unit, with a paper trail a brand's own auditors can follow.
- ISO 14001 environmental management system
- Environmental aspects of manufacturing — refrigerant handling, waste, energy — managed under a system with continual-improvement obligations.
Why it matters: Responsible-manufacturing evidence for a brand's own ESG reporting.
- BIS product certification
- Product certification for the air-conditioner ranges Ezentech manufactures for brand partners.
Why it matters: Ranges that are certified for the Indian market before a brand puts its badge on them.
The lab, on camera
Psychrometric testing,
explained.
A psychrometric test holds indoor and outdoor conditions at controlled temperature and humidity and measures what the unit actually delivers: cooling capacity, power input, the resulting ISEER, and airflow. Those are the figures on the specification sheet and on the BEE label.
- Cooling capacity
- Power input
- ISEER
- Airflow
- Controlled temp & RH
Energy efficiency
Efficiency,
on the label.
ISEER — Indian Seasonal Energy Efficiency Ratio — is cooling delivered per unit of electricity over a full Indian cooling season, as rated under the BEE star-labelling scheme. Every figure below is computed from the manufacturer specification sheets.
- Peak rated ISEER on the sheet
- 5.65
- R32 inverter models
- 08
- Of the range on R32
- 100%
- BEE bands on the sheet
- 3★ / 5★
Responsible manufacturing
ISO 14001,
in practice.
Three commitments a brand can put in its own ESG file — each one verifiable, none of them a target we have not met.
Commitments
03 commitments
- Environmental management system
- The plants operate under ISO 14001 — environmental aspects identified, controlled and audited, with continual-improvement obligations rather than one-off claims.
- Lower-GWP refrigerant
- Every model on the sheet runs R32, which has a lower global-warming potential than R410A and a higher volumetric capacity, so charge sizes are smaller.
- Efficiency on the label
- Inverter platforms rated up to ISEER 5.65 in Ezentech's own accredited lab — energy efficiency measured, not asserted.

asks first.
Buyer questions
05 questions
What does NABL accreditation mean for a buyer?
NABL accredits a laboratory's competence to carry out specific tests. Ezentech's psychrometric lab is accredited, so the cooling capacity, power input and ISEER figures on its sheets are measured under an accredited, audited method.
Which ISO standards does Ezentech operate under?
ISO 9001 for quality management and ISO 14001 for environmental management.
Are Ezentech's product ranges BIS-certified?
Yes — Ezentech manufactures BIS-certified air-conditioner ranges for brand partners.
Which refrigerant do Ezentech units use?
R32, across every model on the current specification sheet.
Can I get copies of the certificates?
Yes. Certificates and test documentation for a programme are shared during the RFQ process — ask for them in your enquiry.
