Accessories for water cooling

The use of water cooling is an advantage, but not mandatory. The temperature-optimised aluminium profile of the PRO² LED bar also provides passive cooling. But with active water cooling, the LEDs are optimally cooled, the waste heat from the LEDs is put to effective use and the aquarium is heated.

Water cooling: In spite of the much higher efficiency of LEDs compared with conventional lighting systems, LEDs also convert part of the energy they consume into heat. This heat must be conducted away by a cooling system, either passively through an aluminium profile and/or actively.

The PRO² LED lamps can operate with a water cooling or heat recovery system, which means the LEDs are always within their optimum temperature range. Because starting of the first day a LED, whether for household or aquarium application, loses slowly but continuously its luminosity. The value of LED chip service life (eg 50,000 hours), as it is found in the technical data, says that the LED delivers only 50% of the former luminosity after this period of operation. An optimal working temperature through cooling significantly counteracts this creeping process.

Heat recovery: Heat energy that is lost in conventional LED lighting and remains unused is effectively used with the PRO² LED lamps. The system supplies the resulting waste heat to the aquarium water and thus noticeably relieves the aquarium heating.

The water cooling with heat recovery becomes a great advantage of your aquarium.
Simple - ingenious!

* The graphic shows exemplary values: Room temperature, heater, water volume etc. must be taken into account and lead to individual results.

Advantages and functions:

• The LEDs work within their optimum temperature range, which maximises the output of the LEDs and extends their period of peak lighting performance.The heat recovery / water cooling system uses the waste heat from the LEDs and feeds the aquarium with warm water.
• The electricity consumed by the aquarium heating is drastically reduced.
• PRO² LED bars with heat recovery pay for themselves very much quicker than other LED lighting systems: Lower electricity consumption with light and heat!
• The two integrated XL channels that provide water cooling to the LED bars ensure high flow rates, excellent cooling properties and very high efficiency.
• You can feed the water cooling system through a bypass in your filter system's water circulation circuit or by means of a separate pump.
• The system is nearly maintenance free and extremely durable thanks to high quality components manufactured from stainless steel and silicone.
• As you would expect, you can connect several PRO² LED bars together in parallel or in series.
• Low-noise operation

Water cooling connection

1. 180° silicone bends for connecting the feed and return sides. (Included in the scope of supply)
2. Cooling and warm water connections; hoses can be cut to length as required.
3. Version 1: Cooling water feed by bypass. Select an adapter (T-connector) that matches the existing hose system.  Use the hose line that feeds the filtered water.
   Version 2: Alternatively the cooling water can be taken directly from the aquarium by means of a minipump. (See Accessories)
