NCR (Non-Conformance Report) - How to Raise an NCR Effectively
In QA/QC, identifying a non-conformance is only the first step.
The NCR should clearly communicate what is wrong, where it occurred, what requirement was violated, and what action is required.
Key points while raising an NCR:
NCR Number & Date
Exact location / Item / Joint No.
Clear description of non-conformance
Drawing / Specification / WPS reference
Actual condition vs. required condition
Size, location & extent of defect
Sketch / Photograph / Section view, if required
Immediate action taken
Corrective & preventive action
Responsible department & target date
Re-inspection and final closure
Simple flow:
Identify Document →
Raise NCR →
Root Cause
Corrective Action
Re-inspection
Close
A well-documented NCR helps in traceability, corrective action and continuous quality improvement.

AIR-COOLED CHILLER |
TECHNICAL NOTES
An Air-Cooled Chiller is a self-contained refrigeration system that removes heat from chilled water and rejects it directly to the ambient air through condenser coils and fans.
Key Engineering Points:
Refrigeration Cycle:
Compressor
Condenser
Expansion Valve →
Evaporator
Compressor
Chilled Water Circuit:
Warm return water enters the evaporator heat is transferred to the refrigerant → cooled water leaves the chiller and supplies the building.
Typical CHW Design:
7°C Supply/12°C Return - actual design conditions depend on the project and manufacturer.
Ambient Temperature:
Higher outdoor temperatures can reduce cooling capacity and increase condensing pressure and compressor power.
