We 'aeropure uv systems, pune' manufacture and supply uv lamp systems to be fitted inside ahus & also other uv products suitable for germicidal irradiation, odor elimination, energy efficiency and improving iaq. The installation of uvgi devices lead to electrical energy savings to the tune of 10 to 15% by improving heat transfer efficiency of ahu cooling coil, which in turn results in reduction of chilled water requirement from the chiller. ultraviolet light is electromagnetic radiation with wavelengths shorter than visible light. At 253.7 nm wavelengths uv is mutagenic to bacteria, viruses, molds and other micro-organisms. At a wavelength of 253.7 nm, uv will break the molecular bonds within micro-organism dna thereby destroying them, rendering them harmless or prohibiting growth and reproduction. The typical problem with hvac is the growth of mold and mildew on cooling coils. Mold and mildew thrive in wet, dark environments. When ahu is in use, condensation often forms on the cooling coils. This moisture from condensation creates the ideal environment for mold and mildew to grow. This mold and mildew attracts deposition of dust on coils. During operation of ahu, this layer grows in size and reduces the airflow through coils and reduces the heat transfer efficiency between cooling coil & air. The uv system addresses the root cause; i.e. Mold & mildew growing on the cooling coils, prohibiting any deposit formation on the cooling coils and keeps them in brand new condition.
