Rendering Ventilation Upgrade Location: Christchurch, New Zealand Year: 2019 In 2019, our team had the opportunity to work on an air exchange system project for a food industry client located in Christchurch, New Zealand. The client was facing issues with insufficient air exchange in multiple process rooms, resulting in foul odours that posed a health risk for operators. Our team designed and installed a new extraction fan with increased capacity, along with a replacement fan and new ducting, to feed into the existing BioFilter. We also covered external process tanks and included them in the extraction system to help mitigate the odour issues. Since the new system was installed, it has performed well, helping to improve air quality and reduce health risks for operators at the client facility in Christchurch.
