- CNWINNEX Explosion-Proof Compressor: Static Pressurization + Multi-Layer Intrinsic Safety, an IECEx-Certified “Compliant Heart”The safety of an explosion-proof air conditioner is never determined by the enclosure alone. As the core moving component of the refrigeration cycle, the compressor is both the center of energy conversion and one of the potential ignition sources that most requires systematic control in hazardous areas. CNWINNEX’s affiliated company is China’s only explosion-proof compressor company holding an independent IECEx certificate. The compressor uses static positive-pressure protection as its primary structure, combined with an increased-safety junction box, intrinsically safe sensing and protection components, and a certified solenoid valve—forming a clearly layered, independently traceable explosion-proof system. Marking: Ex eb ib mb pxb IIC T4 Gb; ambient temperature range: -25°C ≤ Tamb ≤ +60°C.
CNWINNEX’s affiliated company is China’s only independently IECEx-certified explosion-proof compressor manufacturer. Certifed to IEC 60079-0/-2/-7/-11/-18, marking Ex eb ib mb pxb IIC T4 Gb, -25°C to +60°C. The compliant core inside CNWINNEX explosion-proof air conditioners.The compliance of an explosion-proof air conditioner begins with its most critical component. CNWINNEX’s affiliated company is China’s only explosion-proof compressor company holding an independent IECEx certificate—a qualification whose significance lies not in the document itself, but in the fact that it places the most critical moving part of an explosion-proof air conditioner within an independent, traceable, and verifiable international compliance framework. In oil and gas, chemical, offshore, and hazardous-material storage applications, the compressor is both the heart of the refrigeration cycle and a potential ignition source. The depth of a compressor’s explosion-proof compliance directly determines the safety margin and certification credibility of the complete unit in Zone 1 and Zone 2 hazardous areas.
CNWINNEX Explosion-Proof Split Wall-Mounted AC Passes IEC 60335-2-40:2022 Test Report and Achieves Australian SAA Certification, Expanding Its Compliance FootprintWe 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.
CNWINNEX BKT-26 Mobile Packaged Explosion-Proof Air Conditioner: 25kW Plug-and-Play Cooling for Temporary and Mobile Hazardous Work ZonesThermal control requirements in hazardous areas are not always fixed. Plant turnarounds, emergency repairs, confined-space operations, temporary hazardous-material storage, and temporary explosion-proof electrical rooms share a common profile: the work location moves, the deployment window is short, and explosion-proof compliance does not relax because the job is "temporary." Conventional fixed explosion-proof air conditioners struggle in these scenarios—long installation cycles, complex piping modifications, and equipment that cannot follow the work face. The CNWINNEX BKT-26 Mobile Packaged Explosion-Proof Air Conditioner is engineered to fill this gap: 25kW cooling capacity in a fully integrated monoblock, heavy-duty swivel casters with brakes, and dual lifting provisions (top lifting eyes and bottom forklift pockets) that let an Ex db ib mb IIC T4 Gb certified unit be moved, positioned, and commissioned as work demands shift.
CNWINNEX Rooftop Packaged Explosion-Proof Air Conditioner: 200kW All-in-One Thermal Control That Rethinks Installation for Marine & Offshore Hazardous AreasLarge-capacity climate control in hazardous areas has long carried a structural contradiction. Split explosion-proof systems distribute the compliance burden across indoor units, outdoor units, refrigerant piping, and on-site coordination—each interface a potential gap in the certification chain and a drag on project schedules. Conventional floor-standing or cabinet units, meanwhile, consume premium work area in spaces where every square meter already carries operational and safety value. The CNWINNEX Rooftop Packaged Explosion-Proof Air Conditioner resolves this by moving integration upstream: cooling, heating, humidification, steam heating, and the complete explosion-proof electrical control system are assembled and factory-tested in a single rooftop monoblock. On site, only power, water, and duct connections remain. With 200kW rated cooling and heating capacity and 36,000 m³/h airflow, it delivers centralized, uniform thermal control within an ATEX Zone 1/2 compliance envelope.
CNWINNEX Explosion-Proof Split Wall-Mounted Air Conditioner: Wide-Temperature Cooling from -7℃ to 55℃ for ATEX Zone 1 & 2 Hazardous SitesIn oil and gas stations, chemical plants, and high-temperature work zones on offshore platforms, the question is not whether an air conditioner can cool—it is whether it can keep cooling when the ambient temperature pushes past 55℃, while simultaneously meeting the non-negotiable compliance requirements of Zone 1 and Zone 2 hazardous areas. Safety and performance are not a trade-off. They are the baseline.
The CNWINNEX split wall-mounted high-temperature explosion-proof air conditioner is engineered for exactly this intersection. It delivers stable cooling across a -7℃ to 55℃ ambient range, operating reliably through both extreme heat and sub-zero cold. With explosion protection marking Ex db mb IIC T4 Gb, it is suitable for Zone 1 and Zone 2 explosive gas atmospheres and designed in strict compliance with ATEX Directive 2014/34/EU.
