Croffles – Smarter Containment for Demanding Environments

Our Croffles offer a highly effective and low-maintenance solution for liquid surface control in industrial storage tanks. Specifically designed to tackle common issues such as evaporation, odour release, fume emissions, and heat loss, these floating covers are especially beneficial in chemical processing environments, wastewater treatment facilities, and heated or cooled storage tanks. Their versatility makes them a practical choice across a wide range of applications where product integrity, environmental compliance, and energy efficiency are top priorities.


Deployment

When deployed, the hollow plastic balls automatically float and evenly spread across the liquid surface, forming a dense, self-arranging blanket. As a result, this tight configuration covers over 91% of the surface area, creating an effective barrier between the liquid and surrounding air. This passive system requires no installation or adjustment, making it ideal for both new setups and retrofits. Consequently, it dramatically reduces mass and heat transfer, helping to maintain product stability, lower energy consumption, and extend the operational life of storage systems.

Built-In Thermal Insulation Properties

In addition, each Croffle ball holds an insulating air pocket, while the naturally low thermal conductivity of plastic further improves heat retention. Combined, these features create a passive thermal insulation system that not only limits heat loss in heated tanks but also helps maintain temperature in cooled or sensitive liquids. This built-in insulation reduces reliance on external heating or cooling systems, helping to lower energy consumption and operational costs.

 

Furthermore, beyond thermal efficiency, floating ball blankets significantly reduce liquid evaporation, suppress the release of odorous or hazardous vapours, and limit oxygen absorption ? a critical factor in maintaining chemical integrity and shelf life. These benefits make Croffles ideal for a wide range of industries, from chemical processing to food and beverage production.

What's more, one of the standout advantages of Croffles is their non-disruptive design. Equipment and products can move through the liquid surface with ease. As they pass, the balls are gently pushed aside and then quickly reform the cover once movement stops. Additionally, the balls rise and fall with changing liquid levels and adapt naturally to shifting surface areas ? stacking into double layers when space is reduced and spreading out again as levels rise. This dynamic responsiveness ensures continuous coverage without manual adjustment.
