In-line UVC LED water sterilizers for water purifiers and appliances, in 2, 2.5 and 5 L/min capacities.
The JIN INTER UV LED filter disinfects water as it flows. Water passes through a quartz tube while UVC LEDs outside the tube irradiate it, damaging the DNA/RNA of microorganisms so they can no longer reproduce. No mercury and no chemicals are used. The compact, low-power module runs from a DC 24 V supply and drops into the water line of a purifier or appliance.
The module is robust, frugal and easy to power, which keeps the circuit and the parts around it as simple as possible.
Built to tolerate high water pressure and the water hammer caused by valve opening and closing, for up to 150,000 cycles. Maximum water pressure: 100 PSI.
Only 2.5 W, 3.5 W or 5.5 W (±15%) at DC 24 V, depending on the model.
Runs on DC 24 V, so it can use the same DC supply as the other electrical components in your product. No separate power source is needed.
It can be energized all the time, so no dedicated switching or timing circuit is required. Keep water inside the unit at all times and avoid dry operation.
Microorganisms enter with the flowing water.
UVC LEDs outside the quartz tube irradiate the water and damage microbial DNA/RNA, preventing reproduction.
The UVC-treated water flows out of the outlet, with nothing added to it.
Disinfects with UVC light only, without mercury or chemical disinfectants.
A ray-tracing-based reflective structure directs the UVC light into the water and limits light loss.
Reduces UV exposure of internal fittings and plastic tubing, protecting them from UV degradation.
A small cylindrical body fits into the water line, even where installation space is limited.
SUS 304 stainless steel housing and water-safe materials for water treatment applications.
A built-in LED shows the operating status at a glance.
All models share the same DC 24 V supply, UVC wavelength and 100 PSI pressure rating. Choose by the flow your product needs.
Compact
0.5 - 2 L/min
The smallest unit, with a Ø19.1 mm body for tight spaces in countertop and under-sink purifiers.
Built-in flow sensor
2.5 L/min
A built-in flow sensor switches the UVC LED on only when water is flowing, so no external control is needed. DC 24 V adapter included.
Highest flow
1 - 5 L/min
The highest-capacity unit, for purifiers and appliances that need up to 5 L/min.
