CNWINNEX introduces its Onshore Explosion-Proof Pressurized Control Rooms and Electrical Houses, specifically engineered for demanding onshore conditions. By integrating leading pressurized technology with modular construction, we provide an "intrinsically safe" core for intelligent control and power distribution, ensuring absolute protection for personnel and equipment within hazardous areas.
In high-risk sectors such as petroleum, chemical, military, pharmaceutical, and energy, operational safety is the lifeline of any enterprise. We understand that in environments with explosive gases or dust, even the slightest oversight can lead to irreversible losses.

Core Advantages: More Than Explosion-Proof, It‘s About Reliability
● Intrinsically Safe Pressurization Technology
Our products comply with ATEX and IECEx standards (e.g., Ex pz/px, py). By continuously introducing protective gas into the interior, a stable positive pressure is maintained, effectively preventing the ingress of an external explosive atmosphere. The system features automatic compensation, purge cycles, real-time pressure monitoring, and alarm interlocks, ensuring the control room remains safe under all operating conditions.
● Customizable Modular Design
Whether serving as an integrated central control room or an independent VFD (Variable Frequency Drive) electrical house, we tailor every detail to your process. From dimensions and layout to electrical interfaces and material selection (such as stainless steel or carbon steel with anti-corrosion coatings), our solution perfectly matches your site’s spatial and functional requirements.
● Robust Physical Protection & Environmental Adaptability
Designed to withstand onshore challenges like dust, sand, rain, snow, solar radiation, and extreme temperatures, our enclosures feature high-strength structures with excellent waterproofing (IP65), corrosion resistance, and thermal insulation. Whether in scorching deserts or frigid arctic regions, your sensitive equipment remains securely protected.
● Intelligent Monitoring & Unattended Operation
Integrated with advanced PLC control systems and HMI touch screens, the unit provides real-time data on internal pressure, temperature, and airflow. It supports remote alarm transmission and DCS integration, enabling "unattended, remote monitoring" which significantly reduces the risks and costs associated with manual inspections.
● Technical Specifications & Application Scope
Hazardous Area Classification: Suitable for Zone 1 and Zone 2 with IIA, IIB, IIC explosive gas atmospheres; and Zone 21 and Zone 22 with combustible dust atmospheres
Temperature Class: T1 to T4
Enclosure Rating: IP65 for both indoor and outdoor installation
Target Industries: Petroleum, chemical, military, pharmaceutical, warehousing, and other flammable/explosive environments.
Typical Applications
● Onshore Oil & Drilling: Drilling rig control rooms, Mud pump cabins.
● Refineries & Chemical Plants: Field analyzer houses, Equipment shelters, Power distribution rooms.
● Hazardous Chemical Warehousing & Terminals: Loading/Unloading control stations
● Pharmaceutical & Fine Chemical: Explosion-proof electrical enclosures/rooms.
● Energy & Power: Gas power plant control rooms, Energy storage system electrical houses.
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.
