We were approached by a client looking to create a bespoke assembly for use with a water sterilisation application.
Inert to UVC
Good transmission rate, so the output of the lamp is not dramatically reduced.
Ability to be reformed to apply a flange at one end and various bends along the length
Flange diameter required - 15mm nominal
Metric off the shelf size tubing, as small batch quantities required in the first instance
FEP tube 4mm ID x 5mm OD is available from stock.
FEP is inert to UVC - it doesn't become brittle or discoloured over time, unlike other general-purpose plastics.
Approximately 15% of the lamp output is lost when using a 0.25mm thick FEP tube or FEP heat shrink sleeving.
Flanging tools were developed in house by our R&D team, to create a 15mm diameter flange which is on the top end of what's usually achievable on a tube of this size.
3 different angled bends were formed along the length of the tube, which enabled the assembly to be orientated within the equipment.
