Microspear® UV disinfection systems are specially designed in conjunction with Enviolet to produce the best results. This ensures that contamination is not carried forward into subsequent process steps and optimises functionality of machinery. On the basis of water analyses and the description of your installation, we will be able to design a UV disinfection unit with a performance guarantee.

Open Tank Disinfection

Microspear® UV disinfection units are particularly suitable for rinsing processes and hygienic storage of water and aqueous solutions.

A unique feature of the Microspear® is that it has internal grounding inside the protection tube of the submersible UV lamp.  Should the lamp become damaged then the complete system will switch to zero voltage due to the ground-fault-protection switch.

Microspear®  Submersible UV-unit

The Base unit Microspear®  is the basic module for UV disinfection of water within tanks and at the point of actual rinsing. Dependant on the tank size and the UV absorption of the water to be treated, the base unit may be extended with additional Microspear® units. In this way the Microspear® system can be adapted to the particular requirements of your site and processes. In some applications Microspear® units are combined with Microfloat® technology for optimum results.

The Microspear® base unit comprises the following as standard:

  • 1 off immersion lamp consisting of:
    • 1 protection tube made of ultrapure quartz glass with threaded PP-fitting, diameter 32 mm
    • 1 off 2 pin 40W-UV- lamp with an UV-output of 13 W at 254nm. The lifetime of the lamp is 8000 operating hours;
    • 1 piece closing plug with grommet out of stainless steel or PVDF and EPDM gasket 20 m UV-protected cable
  • 1 off 230 V/50 Hz electrical cabinet incorporating:
    • Mounting kit
    • Ballast
    • Earth leakage circuit breaker
    • Operating hour meter
    • Fuses & terminal block
    • ON/OFF Switch
    • Fan and filter unit for air cooling which is needed for more than 5 Microspear® units
  • Integration: by user, plug and play
  • Instruction manual

Additional lamp units can be supplied as required by the size or number of tanks to be disinfected.

There are also various optional accessories available including mounting plate, protective cage, lamp monitoring device, level sensors and additional cable.  It is also possible to supply an ATEX approved version of the Microspear® if required.

System Design

In order for us to recommend the most suitable Microspear® system to meet your needs we will require the following information with your initial enquiry:

  • Tank dimensions: LxWxH or DxH in metres
  • Filling volume in m³
  • Flow rate in m³/h
  • Water sample (50ml) or description of water (e.g. DI-Water, Recycling water, Rain water etc). Please note that there will be a charge for analysing your water sample if this service is required.
  • Tank construction material
  • Temperature of liquid to be treated
