- Less maintenance: Long-lasting LEDs need no lamp changes.
Item no. 36288
The WM aquatec UV-C LED water disinfection unit treats water directly in the fresh water line and switches on automatically when water is drawn. Treatment becomes part of your everyday camping routine without a separate operating step.
UV-C treatment without chemical dosing or warm-up time
Short-wave UV-C light irradiates the water flowing through the unit. This is a physical process that requires no added chemical disinfectants. The LED light sources are mercury-free.
The LEDs need no start-up or warm-up phase and are switched on only while water is being drawn. This limits active operating time to actual demand. Maximum power consumption is 14 W; the specified current draw is 0.02 A in standby and 1.2 A in operating mode.
Match the flow rate to the stated reduction performance
The unit supports a flow rate of up to 8 l/min. The stated reduction figures refer to E. coli and depend on the flow rate:
- 99.999% at 2.25 l/min
- 99.99% at 5 l/min
- 99.9% at 8 l/min
The 99.999% figure applies at 2.25 l/min, not at the maximum flow rate. Take this relationship into account when planning your water system. Multiple units can be connected in parallel for higher flow rates.
Long operating life without routine lamp replacement
The stated maximum service life is 5,000 hours of water draw-off at an average water temperature no higher than 30 °C. At an average of 365 hours of water draw-off per year, this maximum figure equates to more than 13 years. The number of switching cycles is unlimited.
No lamp replacement is required. The unit is described as maintenance-free provided the fresh water system is cleaned annually. Cleaning the water system therefore remains part of its regular care.
Recognise operating notifications through visual and audible signals
The unit incorporates current/function monitoring, temperature monitoring and service-life monitoring. Visual and audible signals make the corresponding notifications apparent.
Plan a compact retrofit that suits your installation
The LED light sources, driver and control unit share a stainless steel housing. The unit measures 113 x 159 x 105 mm excluding connections and weighs 0.9 kg. It is suitable for submersible and pressure pumps and requires a 12-18 V DC supply.
Hose tails for 9/10 mm and 12/13 mm hoses are included for connection to the water line. The connection kit also contains elbows, retaining rings, hose clamps and electrical branch connectors. Maximum permitted water pressure is 8.3 bar.
The installation location described for the Mercedes-Benz Marco Polo is the lower wardrobe compartment. The supplied information does not explicitly confirm compatibility with W447 or W639 models. For your particular vehicle, check the available space, hose dimensions and electrical supply against the technical specifications.
The unit is offered with an optional installation service. Choose the version with or without workshop installation to suit your installation plans.

How does the UV-C LED water disinfection unit work?
The WM aquatec unit is installed in the fresh water line and exposes the water flowing through it to short-wave UV-C light. It switches on automatically when water is drawn. The process requires no added chemical disinfectants; the LEDs are mercury-free and need no warm-up time.
What flow rate and reduction figures are specified?
The maximum flow rate is 8 l/min. The stated figures refer to E. coli reduction: 99.999% at 2.25 l/min, 99.99% at 5 l/min and 99.9% at 8 l/min. The highest reduction figure therefore does not apply at maximum flow. Multiple units can be connected in parallel for higher flow rates.
Where is the unit installed in the Marco Polo, and which models are confirmed?
For the Mercedes-Benz Marco Polo, the described mounting location is the lower wardrobe compartment. The information does not explicitly confirm compatibility with W447 or W639 models. Available space, water connections and electrical supply must be checked for the particular vehicle. An installation service is optional.
What are the connection and installation requirements?
The unit is suitable for submersible and pressure pumps and requires 12-18 V DC. Hose tails for 9/10 mm and 12/13 mm hoses are included. The housing measures 113 x 159 x 105 mm excluding connections and weighs 0.9 kg. Maximum water pressure is 8.3 bar and maximum ambient temperature is 55 °C. The recommended water temperature is 0-38 °C. Maximum power is 14 W; current draw is specified as 0.02 A in standby and 1.2 A in operating mode.
How long can the unit remain in service?
Maximum service life is 5,000 hours of water draw-off at an average water temperature no higher than 30 °C. At an average of 365 hours of water draw-off per year, this maximum figure equates to more than 13 years. The number of switching cycles is unlimited.
What maintenance is required?
The unit is described as maintenance-free provided the fresh water system is cleaned annually. No lamp replacement is required. Installing the unit does not remove the need for regular cleaning of the water system.
How is operation monitored?
The unit incorporates current/function monitoring, temperature monitoring and service-life monitoring. Notifications are provided through visual and audible signals.
What is included in the package?
The package contains the UV-C LED water disinfection unit, a Service-Card and operating instructions. The water connection kit includes two push-in hose tails each for 9/10 mm and 12/13 mm hoses, two 90-degree push-in elbows, four retaining rings and two hose clamps. The electrical connection kit contains three branch connectors.
