Since 1974, DWD International has designed, manufactured, installed and maintained HVAC and pressurization systems that withstand the most challenging conditions. DWD was one of the first companies to offer explosion-proof, corrosion-resistant HVAC equipment, and we continue to lead the industry with innovative designs and quality equipment. In 1990, DWD pioneered a variable frequency drive (VFD) pressurization unit that offers 100% stand-by in a single cabinet, minimizing outside-air loads while still meeting NFPA 496 standards.
Safety is an integral part of our culture, from our internal shop operations to the installation, commissioning and maintenance of systems at your facilities. All DWD personnel are engaged in our behavioral-based safety management processes. We maintain all necessary training, certifications and documentation to meet SEMS requirements.
Our specialty lies in creating HVAC and pressurization systems that are able to operate in extreme temperature ranges (from -40°C to 55°C) and resist corrosion. DWD systems are ideal for specialized facilities, including:
