Sunsun CUV-655 55W UV-C Clarifiers (CUV-655 55W UV)

SUNSUN CUV-655 55W UV-C Lamp
The SunSun CUV-655 is a 55 W UV-C lamp designed for water features and ponds with a capacity of up to 65,000 liters. The device works with systems with a flow rate of up to 8,000 l/h and helps reduce the growth of floating algae, bacteria, and other microorganisms responsible for deteriorating water quality. Thanks to UV-C radiation, the water becomes clearer without the need for chemicals, which helps maintain safe conditions for fish and plants. The model is equipped with universal hose connectors for diameters of 25, 32, and 38 mm, and a 5-meter power cord facilitates installation in a convenient location within the filtration system.


Technology that Enhances the Effectiveness of UV-C Radiation
Inside the unit, a special design directs the water flow around the UV-C lamp in a way that prolongs contact with the radiation. As a result, the disinfection process is more effective than in standard flow-through systems. Additionally, the manufacturer has included a stainless steel reflector that reflects unused UV-C rays back into the treatment chamber. This increases effectiveness without the need for a more powerful light source and simultaneously reduces the fouling problem typical of conventional reflectors.


Clear water without the use of chemicals
The UV-C lamp works by exposing the flowing water to ultraviolet radiation, which destroys the algae responsible for the “green water” effect. Dead microorganisms clump together into larger clusters that can be easily removed by a mechanical or biological filter. The manufacturer states that with a properly selected filtration system, the first results—visibly clearer water—can be seen in as little as 14 days. The best results are achieved when the UV-C lamp is used in conjunction with a biological filter, which removes any remaining contaminants from the tank.


A well-thought-out design for year-round operation
The CUV-655 model is equipped with two ferrite magnets housed within the casing, which, according to the manufacturer, aid in the magnetization of the flowing water. The housing is made of durable ASA and ABS plastics that are resistant to the conditions found around a pond. The symmetrical design allows the connection ports to be used as both an inlet and an outlet, making it easier to integrate the unit into an existing system. The dimensions are 691 × 261 × 118 mm, making it easy to verify the available installation space before purchasing. For Koi ponds, it’s important to note the manufacturer’s recommendation of approximately 3 W of UV power-C per 1,000 liters of water, which means that the 55 W model is ideal for Koi ponds with a capacity of approximately 18,000 liters.
