Submersible UV-C lamp

Submersible UV-C lamp

Is a simple device that can be used to effectively eliminate the growth and development of unicellular algae, funnel algae, yeasts and partially bacteria and viruses in your rearing system.

It works on the principle of emitting UV-C radiation with a wavelength of 253.7 nm into the water, thereby disrupting the DNA of microorganisms. The microorganisms do not multiply further. An important feature of UV-C radiation is that it does not cause resistance in microorganisms.

The effectiveness of the UV-C lamp depends mainly on the intensity of the radiation and the illumination time. In the case of water disinfection, the transparency of the water also matters. Cloudy water causes a lower efficiency of the UV-C lamp.

How to size the UV-C lamp ?

In RAS , i.e. in recirculating fish farming, a conversion of 5 -10 W /m3 is used, depending on the intensity of the farming and the flow rate.

In aquaculture, where often only the inflow water is treated (inflow to the hatchery, troughs, etc.), it is better to assess each case individually based on the specifics of the particular farm. If you are interested, please do not hesitate to contact us.

Composition of the UV-C submersible lamp

• amalgam germicidal fluorescent lamp
• protective quarts tube
• electronic ballast
• 4 PIN socket
• connecting fitting and cable gland
• wiring

Installation of a UV-C submersible lamp

• only the UV reactor can be immersed = quartz tube only
• fittings, wiring and ballast must not be immersed in water
• horizontal and vertical installation is possible
• submersible UV-C can be installed in pipes, UV chambers, inter-chamber biofilters, prefilters etc… The advantage is the easy expansion and reinforcement of the system. Easy installation and service.

• in case of installation on a pressure pipe, it is better to install the UV lamp on a bypass
• UV radiation must not penetrate into the biofilter where it would damage the nitrifying bacteria
• can only be connected to a 230V AC socket which is protected by a 30mA current protector
• the electronic ballast is supplied with brackets for wall mounting
• PP or stainless steel housings can be used for safe installation, which can be used to create a UV system as required

Technical specification

Length of cable between ballast and lamp is 2m, length of mains cable is 3m.
