Product information

JT Cover is an effective floating cover system for liquids and fluids. It consists of hexagonal UV-protected plastic elements, made from recycled material, which are poured on the liquid’s surface where they automatically spread and float together, thus establishing a tight cover. The elements allow free access to the tank and working without removing the cover first.

JT Cover is a maintenance-free, advantageous and highly competitive system which has a lifespan of, at least, 25 years. It can be removed and used again on another surface.

Our hexagonal covers have been proven to significantly reduce odour and smell emissions from liquids, such as wastewater, slurry etc.


The application of JT Cover is quick and easy. The hexagonal covers are delivered in big bags and simply has to be dropped into the tank, basin or pond where the elements will spread, float together and cover the odorous liquid effectively. The covers fit together like a puzzle and thereby establish a tight and flexible cover.


The specific weight of each element ensures that JT Cover does not dive when stirring in the tank. They always stay afloat even if an agitator is used below the surface. The elements will automatically form a tight cover again when the stirring has ended. All kinds of mixers can be used without removing the floating cover. The elements will just slide aside and re-establish themselves after the end of the operation. 

Suction pipes, pumps

The diameter of 313 mm ensures that JT Cover will not be an obstacle for suction pipes and pumps. Even 10″ suction pipes can be used directly in the tank without removing the elements. They will float apart and automatically restore the cover when the suction pipe or pump is removed.
