Product Features
* The unit features an auto-restart function after power recovery, enabling fully automatic, unattended operation.
* Supports RS485 communication for network integration of units (optional).
* The unit is equipped with dry contact terminals, allowing for functions such as fire alarm interlocking.
* Designed to aptly address various working environments, it comes in multiple types and models with a wide range of cooling capacities. This meets the needs for cooling, heating, dehumidification, positive pressure, and ventilation in special occasions involving various explosive gases.
* It boasts an attractive appearance and small footprint, making installation and maintenance simple and convenient.
* Comprehensive functionality: Cooling, heating, ventilation, and dehumidification meet the needs of different locations.
* Diverse installation options: Vertical ducted type, vertical wall-mounted type, horizontal ducted type, along with private customization services.
* High-efficiency refrigeration system: The heat exchanger utilizes high-performance inner-grooved copper tubes paired with hydrophilic aluminum fin sheets or copper fin sheets. Processed with advanced mechanical tube expansion technology, it achieves optimal heat exchange efficiency. Through scientifically sound refrigeration system design, the compressor and main components operate reliably in different environments. This overcomes common industry shortcomings such as insufficient cooling/dehumidification capacity, frequent unit cycling, and high product failure rates, thereby also extending the product's service life.
CNWINNEX explosion-proof systems are widely deployed in oil & gas, petrochemicals, pharmaceuticals, ports & terminals, mining, power generation, offshore platforms, and other areas where flammable gases or dusts are present. Typical applications include control room climate control, hazardous area logistics and access management, video surveillance & security, pressurized analyzer shelters, robotic inspection, as well as custom explosion-proof enclosures and system integration.
An explosion-proof air conditioner is a specialized HVAC unit designed for hazardous environments where flammable gases, vapors, or combustible dusts are present (e.g., petrochemical plants, gas stations, paint booths, pharmaceutical labs).
The most critical difference from a standard air conditioner lies in “active ignition prevention.” Standard units generate tiny sparks during normal operation – such as when relays open/close, compressors start/stop, or circuits make/break. While safe in normal air, these sparks can be deadly in an explosive atmosphere.
CNWINNEX’s explosion-proof design is based on the T4 temperature class. For high-temperature regions such as the Middle East or areas with extreme summer heat, we offer custom units rated for ambient temperatures up to 60°C (140°F) , ensuring reliable operation without overload in harsh tropical climates. For cold regions, we offer custom units rated for ambient temperatures as low as -50°C (-58°F) , guaranteeing safe operation in extreme arctic conditions.
The explosion-proof rating of CNWINNEX air conditioners is:
Ex 2 G D Ex db ib mb IIB T4 Gb / Ex 2 G D Ex db ib mb IIC T4 Gb / Ex ib mb tb IIIC T130°C Db
●For Gas (G): Ex db ib mb IIC T4 Gb
Suitable for IIC gas groups (including hydrogen, acetylene, etc.), using flameproof (db), intrinsic safety (ib), and encapsulated (mb) combined protection. Temperature class T4 (max surface temperature ≤135°C), Equipment Protection Level Gb.
●For Dust (D): Ex ib mb tb IIIC T130°C Db
Suitable for IIIC conductive dusts, using intrinsic safety (ib), encapsulation (mb), and dust-tight (tb) protection. Maximum surface temperature 130°C, Equipment Protection Level Db.
CNWINNEX products comply with international explosion-proof certification standards such as ISO, CNEX, ATEX, IECEx, SAA, EAC, ensuring safe use in different countries and regions., and BV or DNV (for offshore applications) . Depending on the product type and zone classification, we offer various protection concepts including Ex d, Ex e, Ex ib, and Ex nA, with ingress protection up to IP66/IP67, ensuring safe and compliant operation in hazardous environments worldwide.
