Blue Box Air
Blue Box Air is a Dallas-based cleantech company that restores and maintains commercial HVAC heat-transfer coils using a patented, enzyme-infused bio-treatment process. By cleaning coils from the inside out - with no downtime and no equipment removal - Blue Box improves airflow and heat transfer, cutting building energy consumption and carbon emissions while improving indoor air quality. Its Bio-Automation system keeps coils continuously clean, and the company markets a 'self-cleaning deep coil' that promises far greater heat-transfer surface area than conventional systems.
