Uniquely, these hoses can now provide an electrically conductive option in applications where it is mandatory to use a white hose as opposed to a black one.

Many of the company’s customers face safety issues when they need to convey powders pneumatically through a white hose. Traditionally, white hoses have been electrically insulated and cannot convey static electricity safely. Potentially, this can spark fires and explosions. As experts in polymer engineering, the firm has developed a new kind of rubber with electrical properties that resolves this dilemma, states the company.

Three years in development, the hoses are based on the latest innovation in technology and chemistry. Meeting industry needs, the hoses are compliant for conveying powder in all Atex areas according to the technical specification CEI/TS 60079-32-1, Explosive atmospheres – Electrostatic hazards, guidance, adds the firm.

Specialist Book „Heat Transfer Technique“The comprehensive standard work „Heat Transfer Technique“ offers not only a detailed and well-founded presentation of the basics of heat transfer technique, but also shows the latest state of the art and the latest regulations in the use of organic fluids. Thematically, the book is rounded off with an overview of property data of organic heat transfer fluids as well as many use cases from practical experience.

The hoses are suitable for a wide variety of industries and applications that are conveying powder pneumatically, in particular those that require white hoses. This includes those conveying PVC granulates, pigments, lime or other coloured powders, as well as dry mix mortar, pulp and paper. Both hoses are food-approved according to the latest regulations and can be used to convey food powders, such as milk powders, sugar, flour, cocoa powders or rice, concludes the company.
