CNWINNEX Explosion-Proof Split Wall-Mounted AC Passes IEC 60335-2-40:2022 Test Report and Achieves Australian SAA Certification, Expanding Its Compliance Footprint

CNWINNEX Explosion-Proof Split Wall-Mounted AC Passes IEC 60335-2-40:2022 Test Report and Achieves Australian SAA Certification, Expanding Its Compliance Footprint

We are pleased to announce that the CNWINNEX explosion-proof split wall-mounted air conditioner has successfully passed the TEST REPORT IEC 60335-2-40 after a 10-week operation testing period, and has concurrently obtained Australian SAA certification. With these milestones, CNWINNEX explosion-proof air conditioners now close the loop across three compliance dimensions—hazardous-area explosion protection, electrical safety, and Australian market access—meeting ATEX Directive 2014/34/EU and related compliance standards, and providing customers on global hazardous-area projects with a more definitive compliance foundation.

10-Week Operation Testing: Stability Proven Through Sustained Operation

The value of a certification lies not only in the certificate itself, but in the real conditions the equipment endures during testing. This verification covered a 10-week operation testing cycle, systematically validating the split wall-mounted explosion-proof air conditioner's electrical safety, temperature-rise control, abnormal-condition response, and overall unit stability under continuous operation. For thermal control equipment required to run continuously and unattended in hazardous areas, issues surfaced during sustained operation testing carry far more reference value than short-duration spot checks—10 weeks of operating data is direct evidence of product reliability.

IEC 60335-2-40:2022: The Safety Baseline for Electrical Heat Pumps, Air Conditioners and Dehumidifiers

The test report was executed against IEC 60335-2-40:2022, in conjunction with the general safety requirements of IEC 60335-1:2010, IEC 60335-1:2010/AMD1:2013, and IEC 60335-1:2010/AMD2:2016, with the test procedure following the CB Scheme. IEC 60335-2-40 is the particular safety standard for electrical heat pumps, air conditioners, and dehumidifiers, covering core safety dimensions including electrical insulation, temperature-rise limits, mechanical strength, and abnormal-operation protection. The CB Scheme, as the IECEE conformity testing and certification system, provides test results with broad mutual recognition across member countries' national certification frameworks. This means the electrical safety performance of the CNWINNEX explosion-proof split wall-mounted air conditioner has been verified under an internationally recognized testing framework, providing reusable technical evidence for market entry across multiple countries.

Australian SAA Certification: Electrical Safety Access for Australia and New Zealand

SAA certification is a key electrical safety certification basis for products entering the Australian and New Zealand markets. Achieving SAA certification means the electrical safety design of the CNWINNEX explosion-proof split wall-mounted air conditioner meets the access requirements of the Australia/New Zealand market, supporting project deployment in both countries. For customers with oil and gas, chemical, mining, and offshore projects in the ANZ region, this certification directly reduces compliance uncertainty during equipment selection and project approval.

Triple Compliance: ATEX + IEC Electrical Safety + SAA Market Access

With this test report and SAA certification, the CNWINNEX explosion-proof air conditioner compliance system now rests on three mutually reinforcing dimensions:

• ATEX Directive 2014/34/EU — EU explosion-proof equipment directive compliance, covering explosion safety requirements for hazardous areas;

• IEC 60335-2-40:2022 (CB Scheme) — the international electrical safety testing baseline for electrical heat pumps, air conditioners, and dehumidifiers;

• Australian SAA certification — electrical product safety access for the Australian and New Zealand markets.

These three address the core project decision questions: "can it be used in the hazardous area," "does it meet electrical safety standards," and "is it admissible in the target market." For customers, this means a relatively complete set of compliance documentation can cover the multiple review requirements of explosion safety, electrical safety, and regional market access during the selection stage—reducing scheme adjustments and schedule delays caused by missing certifications.

Practical Significance for Project Delivery

In hazardous-area thermal control projects, compliance documentation is often as important as the equipment itself. During scheme review, owners, EPC contractors, and classification society/third-party auditors typically verify explosion-proof certification, electrical safety test reports, and target-market access qualifications in parallel. The IEC 60335-2-40 test report and SAA certification completed by the CNWINNEX explosion-proof split wall-mounted air conditioner, together with its existing ATEX compliance, allow project parties to obtain a relatively complete compliance evidence chain from a single supplier—reducing multi-party coordination costs and documentation gap risks.

Continued Investment in Compliance Capability

CNWINNEX has long specialized in explosion-proof thermal control, with products spanning split wall-mounted, packaged, rooftop packaged, and mobile packaged configurations, serving the oil and gas, chemical, power, military, pharmaceutical, and marine/offshore industries. Compliance capability is the underlying competitiveness of explosion-proof thermal control products. We will continue to invest in standards tracking, testing verification, and certification acquisition to deliver verifiable, traceable, and project-ready explosion-proof air conditioning solutions for hazardous-area projects worldwide.
