Unger Nlite brush

How to choose the Unger solar panel brush

1. Weight: How long are you working? The longer you work, the lighter the brush should be.
2. Size: 28cm = standard applications; 41cm = for large surfaces/glass; 60cm = special application e.g. solar panels.
3. Fibers: Soft = normal dirt, delicate surfaces; Rigid = stubborn dirt; Natural = high cleaning power and gentle on surfaces
4. Shape: Rectangular = standard work; curved brush = large surfaces, frames, window sills
5. Nozzles: How many do you need? (2 or more). Do you need spray (rinse) nozzles or jet (remove) nozzles? Do you need flexible nozzle positions?
Caution: Some surfaces are sensitive to scratches. Always test brushes before using them.

Information for use

What length of pole do I need for this building?
To help you determine the correct pole length for your building, as well as the best mix of different types, and the optimum number of extension poles to achieve optimum performance at a cost effective price and with the best rigidity.

Nlite System Maintenance Instructions

Regular cleaning and maintenance:
It is best to carefully wipe all the parts of the poles once a week with a microfibre cloth, preferably damp with pure water. The hose must be clean to prevent dirt and grease from being transferred to the pole. The brushes should also be cleaned regularly in a bucket with pure water and a microfibre cloth to avoid unnecessary accumulation of dirt.

Working with the pole

It is advisable not to pull the elements out of the pole too much to avoid unintentional disassembly. When assembling, pay attention to the elements of the pole. Do not bring them in uncontrolled, this could damage the clamps or injure your hands. Always use the tip at the end of the pole to avoid damaging the lower element.
Adjusting the clamps
To loosen or tighten the clamps, i.e. to adjust the optimum tension, use the green screw in the shape of the Unger logo. Do not overtighten the screw, as this can lead to increased wear on the pole. There are replacement clamps that you can easily install yourself and without glue. On each clamp there is the diameter of the pole to simplify the ordering of these parts.

LDR/Flexion

The length to deflection ratio was developed by the Unger team to obtain a qualified measurement method for an optimal balance between length and deflection rate of water-fed poles. The LDT formula measures the stiffness of the fully extended pole, loaded in the middle with a 5Kg weight. This simulates the average force applied to the pole during use. The result gives the stiffness of the pole. The higher the LDR value, the lower the deflection of the pole.

Bending values

The key factor that determines the rigidity of a pole is the material it is made of.
