Australia: UV system protects against green rot
To manage the risk of Penicillium Digitatum from being introduced to the fruit via the room's “outside air supply”, Australian Ultra Violet recently designed a bespoke UV Bio-wall system for a grower in Northern Queensland to retrofit to the current HVAC system providing fresh air to the fruit processing/de-greening rooms.
In just one pass the Biowall is able to destroy 99.67% as a minimum inactivation figure.
The main challenge was retrofitting the Bio-wall to fit the existing PVC ducting and to fabricate a system that was “serviceable” at height.
To do this Australian Ultra Violet installed a 24” Sanuvox Biowall inside a 1mtr x 200mm diameter Aluminium cylinder for maximum reflection and UV efficiency. The system tapered down to the existing duct with transition flanges at either end.
The Bio-wall section is removable and tethered by chain to hang for servicing or when lamp change out is required in 2 – 3 years.
All lamps are Teflon coated in the unlikely event there should be a breakage, this ensures the quartz would be contained in the sock.
The Biowall system is also monitored 24/7 and linked to a controls interface for remote On/Off controls, lamp timer, fault alerts and alerts facility personal when lamps are due to be replaced after 17000hrs.
