Hollow polymer floating ball blanket in sizes from 10mm to 150mm

Frogspawn Thermal Insulation Spheres form a floating blanket ideal for use on the top of open process tanks.

The system consists of hollow polymer spheres which are usually polypropylene that are floated on the surface of the liquid to provide a continuous insulating layer. Workloads like jigs and components can easily pass through the layer.

The system is used extensively by electroplaters, anodisers, steel processors and chemical manufacturers.

The spheres are supplied in PP as standard and other materials such as HDPE, available on request.
Sizes from 20mm to 50mm in PP are held in stock others are available by special order from our sales office.
