Which are the best wheels to use for a scrubber dryer?
The wheels installed by Eureka on its floor scrubbers are made of either polyurethane or Vulkollan, according to the characteristics of the machine.
The available materials were studied and tested by our Research and Development Department, and in the end the polyurethane compounds were the preferred choice due to their physicochemical characteristics.
In fact this material guarantees an interesting mix of features that provide safety, performance, and resistance to Eureka floor cleaning machines.
First of all, the tyres in polyurethane are full rubber, and therefore are resistant to punctures. They are also not subject to pressure loss, which can happen with pneumatic tyres.
The tyres are elastic, with non-slip characteristics. Based on the results of testing the adherence of the tyres to a wet floor with a range of machines, the best materials were chosen, and different moulds were designed for each scrubber dryer model, taking into consideration that floor cleaning machines operate in constant contact with water and chemicals.
To guarantee even greater safety, Eureka has also selected tyres that are only made of oil-proof compounds, because many of the industrial applications that scrubber dryers work in, have floors that are covered in mineral oil or when it comes to the food industry, animal fats and vegetable oils.
Some competitors propose pneumatic wheels filled with urethane foam. Eureka does not offer this choice because we believe that this type of wheel is subject to deformation. This can happen if the machine is used infrequently, or due to the presence of air bubbles inside the tyre, which in the long term can cause the tyre to become distorted, therefore compromising the distribution of the machine.
An alternative solution to polyurethane wheels, proposed by Eureka, are the wheels made of Vulkollan (patented by Bayer), with even greater characteristics than their polyurethane counterparts, but with an associated increase in price – this type of wheel is fitted as standard where the weight of the machine is such that their use is advisable.
The last key characteristic of scrubber dryer wheels is that they don’t leave any marks where the machine has passed. It wouldn’t be very professional to leave scuff marks at the end of cleaning operations, so to prevent this frustrating possibility all wheels used by Eureka are non-marking.
