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.

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.

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.
