UV-Disinfection of Closed Tanks

Microfloat® and Microspear® were specially developed for the chemical-free disinfection of water in storage tanks and tubs using UV radiation. Microfloat® (floating UV unit) is used in closed tanks with static and strongly fluctuating filling levels. Microspear® (UV immersion lamp) is used in rinses with a more static filling levels and in machines.

Microfloat® irradiates the water and the tank walls above and below the water level with UV-C radiation, so that no biofilm can develop and the water is permanently disinfected. This not only optimally disinfects the water, but also prevents rapid renewed contamination of the water from causing problems; these devices are therefore a real in-situ solution.

Microfloat® disinfects the entire interior of the tank (liquid, gas space and tank wall surfaces) and also forms an effective barrier against contamination via the tank ventilation.

In this way, a chemical-free solution ensures better efficiency than chemicals, because no resistance to UV radiation can develop without the side effects of the disinfectant having to be accepted.

The combined disinfection solution can easily be built into any water vessel, with seamless integration and operation.

The retrofit of existing tanks is easily achieved.

Due to the low energy consumption and high efficiency Microfloat® is the optimum disinfection approach for all tanks with static and varying filling levels.

Typical Applications:

• Climate chambers (scrubber and humidifiers)
• Cooling towers
• Food and beverage
• Pharmaceutical
• Chemical industry
• Surface technology
• Drinking water storage

Custom Quotes

We can provide you with an UV disinfection system designed specifically for your requirements. In order to quote your system we will require the following information:

• Tank dimensions: LxWxH or DxH in m
