Using UV-C to Control Mould in Cold Rooms and Freezer Rooms

Why a counter-intuitive problem exists — and where UV-C becomes a precise engineering solution At first glance, mould growth in cold rooms and freezer rooms feels counter-intuitive.Cold temperatures are commonly associated with preservation, hygiene, and microbial suppression. Designers, operators, and even auditors often assume that low temperature alone prevents biological growth. However, real-world cold storage facilities consistently experience mould growth Read more…

Designing HVAC Systems with UV-C (UVGI): Practical Design Guidance for Engineers

Ultraviolet-C (UV-C), also referred to as Ultraviolet Germicidal Irradiation (UVGI), is increasingly incorporated into HVAC designs to improve indoor air quality (IAQ), suppress microbial growth, and help restore system performance. Both AIRAH (Australian Institute of Refrigeration, Air Conditioning and Heating) and ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) recognise UVGI as a legitimate supplementary engineering control for air Read more…
