Zero Defects.
Absolute Reliability.

Our quality-first philosophy ensures every switchboard, panel, and heater meets global benchmarks — IEC, ISO, and beyond. We don't just test, we guarantee performance.

ISO 9001:2015 IEC 61439 CPRI Type Tested
Our Quality Pledge

Built on Precision, Validated by Science

At HAPL Controls, quality is not an afterthought — it's embedded from design to dispatch. We operate a digitally integrated Quality Management System (QMS) that monitors every stage: raw material inspection, in-process checks, final assembly, and type-testing.

Our advanced in-house high-voltage lab, temperature rise test bench, and IP testing facility simulate extreme conditions to ensure each product withstands real-world challenges. With 100% traceability and calibrated instruments, we deliver switchgear and industrial heaters that perform flawlessly for decades.

State-of-the-Art Testing Facilities

Our in-house labs replicate extreme electrical and environmental conditions

High Voltage Lab

Power frequency withstand, impulse voltage tests up to 75kV. Full compliance with IEC 61439-1.

Temperature Rise Test

Automated 2500A current injection system, thermographic imaging to verify thermal limits.

Short Circuit & Arc Fault

Internal arc tested panels (IEC/TR 61641), certified for fault levels up to 100kA.

IP Testing Chamber

IP42 to IP66 ingress protection verified via water jet & dust chambers.

Dielectric & Partial Discharge

PD measurement up to 100pC sensitivity for MV assets, ensuring insulation health.

Environmental Chamber

Salt spray, humidity, and thermal cycling tests for industrial heaters & outdoor panels.

End-to-End Quality Control

From incoming raw materials to final dispatch, every step follows strict control plans, documented traceability, and real-time SPC.

1
Incoming Inspection – Vendor PPAP, dimensional & material verification, mill test certificates.
2
In-Process Checks – Weld integrity, torque audit, electrical continuity, component alignment.
3
Final Assembly Test – Dielectric strength, functional & protection relay testing, temperature rise sample.
4
Pre-Dispatch Audit – Visual, packaging, documentation, customer witness test (on request).
QC Process

Culture of Zero Defects

Our quality isn't just about machines — it's about mindset. Every employee undergoes regular quality training, Six Sigma green belt programs, and Kaizen events. We maintain 100% calibrated equipment traceable to national standards, and our digital QMS ensures real-time non-conformance tracking and CAPA.

"Quality is never an accident — it is the result of intelligent effort."
