Sealing cables and lines for solar, HVAC and mobile communications systems pose our customers with major challenges every single time. Hauff-Technik can offer roof entries like the SHD swan neck entry or HRD-FUFF(A) wall sleeves with fixed/loose flange that are tailor-made to provide the best possible solution for the corresponding roof construction and customer-specific application. The seals between the building and the cables and lines are established with press seals tailor-made specifically to meet customer requirements. We are happy to propose other solutions on request.
