OASE has an issue with murky ponds! BITRON C range clarifiers effectively fight algae with intelligent UVC technology. Pathogens and bacteria are safely reduced through the UVC radiation.

  • All Bitron devices have well-designed bypass technology. This allows individual adjustment of the water flow which is routed over the UVC bulb via the throttle handle. This makes it possible to set the optimal flow rate. Whether swimming pond, garden biotope, or fish and koi pond – Bitron devices are an ideal fit for any pond.
  • Algae, fish waste, and other pond pollutants can reduce the UVC radiation. The unique and integrated cleaning mechanism of the Bitron C range ensures simple, fast, and permanent cleaning of the UVC light source. This guarantees your customers the sustainable effect of the UVC radiation – for untroubled satisfaction.
  • Integrated magnets protect the system from dangerous lime deposits. Lime that is in the water can assume a crystalline form under the thermal development of the UVC light. These aggressive lime structures can destroy the bulb or block the rotor in the pump. The permanent magnets of the OASE Bitron clarifier prevent these crystals from forming through magnetic treatment of the water. This protects the pond as well as the filtration system and guarantees the unusually long service life of the OASE components.
  • All Bitron range UVC clarifiers are equipped with an indicator light or a control window. Thus the function of the UVC bulb can be checked at any time.
  • The light tubes should be changed after every 10,000 hours of operation, to guarantee the full-strength capacity of the UVC light waves.
  • With the performance they offer, Bitron UVC clarifiers are a valuable component in OASE BIOsys filter systems.

  • All UVC clarifiers have an automatic cleaning system, which ensures that the full output of the light is effectively used.

Mrs Sylvia Edwards Asked:

I have recently bought a second hand Bitron 72. I bought two 36watt 4 pin bulbs before using the item, but find that when using the clarifier, the blue light goes off after about an hour. I have tried it with two different pond pumps, the electric fuse does not blow and, if I turn the switch off for a few seconds and then turn it back on, it will again show the blue light. I wonder if you can give me any information as to why this may be happening.

We Replied:

Dear Sylvia Thank you for your question. Are the bulbs tight in the unit? Sometimes with the Bitron if the lamps are not properly in place they can switch off. It may also be a faulty ballast but without seeing it, it's hard to say. You're more than welcome to bring it into our store for us to inspect and diagnose the problem. Our address is 211 Chester Road, Sutton Coldfield, B73 5BD. Should you wish to contact us further or to place an order, please call us on 0121 355 7701. Thank you for using our online Q&A system. Kind regards Andy Hobson
