A flexible and environmetal-friendly cover

The Clean Cover Concept JT Cover prevents unpleasant smell and reduces ammonia emission from biogas and open slurry tanks. And this in a particularly simple, quick and economical way - without static load on the tank and approved construction measures.

JT Cover covers the surface almost 100% and ensures up to 90% less odour and 84% less ammonia emission.

The Clean Cover Concept is a flexible floating cover of hexagonal elements which are fully environment-friendly. They are made entirely of recycled plastic. The material is practically indestructible and has a lifespan of at least 25 years which makes it possible to clean and use  the elements again on another surface.


JT Cover does always stay on top

The Clean Cover elements cannot dive. They do always stay on top 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 mixeres can be used. 

The diameter of 313 mm ensures that the covers are no obstacles for suction pipes and pumps. Even 10" suction pipes can be used directly in the tank. They elements will simply slide aside, reestablish themselves and keep the surface closed.


No maintenance, no consequential costs

Optimal function and convincing economy ensured by the JT Cover system easily and permanently meet the constantly growing requirements for the environment. There is no expenditure on energy nor any consequential costs, and the cover is completely maintance-free.

With the Clean Cover Concept you are always safe, and flexibilty is ensured. If you want to use JT Cover on larger or smaller surfaces, you can add or remove covers at any time. 


From the big bag directly onto the surface

The application of JT Cover is quick and easy. The covers are delivered in big bags or in bulk in containers from which they can be dropped directly onto the slurry.

The construction of the elements ensures that they automatically spread on the surface and float together. The elements fit together like a puzzle and do thereby establish a tight and flexible cover.

Delivery: In big bags or in bulk in containers

The Clean Cover Concept

JT Cover is a floating and maintenance-free cover system for fluids made of hexagonal Clean Cover elements.

They spread on the surface and automatically form a tight cover.

Odour emission, evaporation and algae formation are massively reduced, and heat loss is prevented.

And this in a particularly simple, quick and economical way - without static load and approved construction meassures.

Directly from the big bag onto the liquid.
