Durable Industrial HVAC Systems for Onshore and Offshore Environments
Since 1974, DWD International has specialized in designing, manufacturing, and maintaining industrial HVAC and pressurization systems engineered to withstand extreme conditions. Our expertise in explosion-proof and corrosion-resistant systems has positioned us as pioneers in the field, with innovations like the first variable frequency drive pressurization unit meeting NFPA 496 standards. We maintain full control over every project phasefrom engineering and fabrication to coating and commissioningensuring precision and quality at every stage. Our in-house processes, supported by a 60,000-square-foot facility, enable efficient management of complex projects while adhering to rigorous international codes and client specifications. With over 45 years of experience, we serve the energy industry globally, delivering systems that operate reliably in temperatures ranging from -40C to 55C.Our commitment to safety, evidenced by behavioral-based safety management and SEMS compliance, extends across all operations, from shop fabrication to on-site maintenance. We prioritize long-term partnerships, offering worldwide field service support and systems designed to last over 30 years. Third-party testing and a stringent internal quality-control program ensure every project meets exacting standards, including ABS, ATEX, and U.S. Coast Guard requirements. Our proprietary coating systems and meticulous electrical panel designs further enhance durability, even in corrosive marine environments. By integrating customization with standardized excellence, DWD International remains a trusted leader in specialized HVAC solutions for offshore platforms, chemical plants, refineries, and more.

Industrial HVAC Systems
DWD designs and manufactures industrial HVAC systems for extreme environments. Our systems ensure reliable operation in temperatures from -40C to 55C, meeting explosion-proof and corrosion-resistant requirements. Clients benefit from customized solutions tailored to offshore platforms, chemical plants, and refineries.
Explosion-Proof HVAC
We engineer explosion-proof HVAC units compliant with NFPA 496 standards. These systems minimize outside-air loads while ensuring safety in hazardous environments. Our pioneering VFD pressurization units provide 100% standby capability, ideal for offshore and industrial facilities.
Corrosion-Resistant Systems
Our proprietary coating systems protect HVAC equipment in corrosive marine environments. Condenser and evaporator coils retain heat transfer efficiency while resisting degradation. These systems are critical for offshore living quarters and coastal industrial facilities.
Custom Fabrication
DWD fabricates custom HVAC skids and cabinetry in-house. All components undergo stringent quality checks per client specifications. This process ensures systems meet exact project requirements, from initial design to final assembly and testing.
Global Maintenance
We provide worldwide commissioning and maintenance for HVAC systems. Our field service team supports systems decades after installation, ensuring long-term reliability. Services include parts replacement, repairs, and compliance testing for international standards.
