Profile: The Nuaire Group designs and manufactures energy efficient commercial & renewable ventilation solutions. We offer heat recovery systems and renewable energy solutions. We develop a wide range of associated fan control sensors, speed controls, and integrated software. We also focus on solar technology to address the increasing need for carbon emission reduction. Our solar air heating system maximizes energy efficiency by capturing solar energy via two roof collectors. The air handling unit is designed using expanded polypropylene which provides good thermal insulation, and incorporates low energy positive input ventilation unit. The system monitors a plurality of temperature sensors located within the ducting of each of the three inlet locations which are collectors, loft space, and fresh air intake. The flow of air through the system is then automatically controlled to optimize energy efficiency. It helps in preventing condensation and moisture build up.
