Bhutan Dustproof and Explosion-proof Distribution Box Factory

Several manufacturers provide dustproof and explosion-proof distribution boxes suitable for hazardous areas in Bhutan, including BARTEC, Extol International, SUREALL, and Atex Delvalle.Key Manufacturers and Offerings1. BARTEC BARTEC offers a wide range of explosion-proof and substance-resistant components and systems for hazardous areas. Their solutions include Ex d (flameproof), Ex e (increased safety), Ex i (intrinsically safe), and Ex p (pressurized) enclosures. They provide low- and medium-voltage power handling solutions, modular motor starters, battery solutions, and distribution boards up to 40kV. BARTEC also offers consulting, engineering, installation, and maintenance services, ensuring compliance with safety standards and long-term reliability . 2. Extol International Extol International supplies control panels and distribution boards for hazardous areas with ATEX certification. Their explosion-proof designs (Ex d / Ex'de) are suitable for Zone 1 (21) and Zone 2 (22) hazardous areas. Materials include stainless steel, aluminum, and cast iron, with protection levels ranging from IP42 (indoor) to IP66 (outdoor). They provide a variety of sizes and configurations for industrial and commercial applications . 3. SUREALL SUREALL manufactures explosion-proof boxes, including junction boxes, panelboards, receptacles, and enclosures for Class 1 Div 1/2 and Class 2 Div 1/2 hazardous locations. Their enclosures use flameproof aluminum alloy, reinforced plastic, or stainless steel to confine electrical arcing and prevent explosions. SUREALL boxes are suitable for gas groups A, B, C, D and dust groups E, F, G, covering Zones 1, 2, 21, and 22 . 4. Atex Delvalle Atex Delvalle produces custom-made local control stations and distribution boxes in stainless steel (AISI 304L/316L) or GRP. Their enclosures are ATEX and IECEx certified for Zones 1, 2, 21, and 22. They offer configurable internal layouts, front installation of control elements, and robust designs for extreme temperatures and outdoor conditions. Their products are suitable for industrial, oil, gas, and infrastructure projects . 5. Prefabricated Substations in Bhutan For integrated solutions, ZBW-type prefabricated substations combine high-voltage switchgear, transformers, low-voltage switchgear, and metering devices in one or several boxes. These substations are designed for urban, industrial, and infrastructure applications, with protection levels up to IP23D and environmental tolerance for temperatures from -25°C to 40°C, wind speeds up to 34 m/s, and ice thickness up to 20mm .Considerations for SelectionHazard Zone Classification: Ensure the enclosure matches the required Zone (1, 2, 21, 22) and gas/dust group.Material and Protection Level: Stainless steel, aluminum, or GRP with IP ratings suitable for dust and moisture protection.Customization: Many manufacturers offer configurable layouts, integrated control devices, and modular designs.Compliance: Look for ATEX, IECEx, or UL certifications for safety and regulatory compliance.Environmental Conditions: Consider temperature, humidity, wind, and altitude specifications for Bhutan's installation sites. These manufacturers provide reliable solutions for dustproof and explosion-proof distribution boxes in Bhutan, suitable for industrial, commercial, and infrastructure projects requiring high safety standards.
