Dan-isoDUAL polyurethane double pipe with flexible inserts
Effective insulation and protection
Dan-isoDUAL polyurethane double pipes offer an excellent solution for the insulation of piping systems that require effective thermal protection and mechanical strength. The insulation, which is made of polyurethane (PUR), combines high temperature resistance and excellent insulation properties, making it ideal for both industrial and technical applications, including district heating systems and other pipe installations where the demands on quality and durability are high.
Flexible inserts for better fit
The insulation half-shells in Dan-isoDUAL are molded in PUR and integrated with a flexible insert in cellular rubber, which is available in different thicknesses. This insert provides a greater internal tolerance, which allows the insulation to be adjusted around compression fittings and other fittings. Dan-isoFlex, which is part of the solution, allows the insulation to be adapted quickly and easily to joints and socket installations. The internal flexibility ensures a perfect fit, while the external side retains the typical advantages of fixed insulating half-shells, such as durability and protection.
Ideal for district heating systems and advanced insulation projects
Dan-isoDUAL is particularly suitable for district heating systems where high demands are placed on both thermal insulation and mechanical protection. The flexible internal insulation in Dan-isoFlex makes it possible to protect all joints effectively, while the external PUR insulation prevents heat loss and ensures optimal energy efficiency. The insulating material helps to minimize energy consumption and protects the pipes against external influences, such as moisture and mechanical damage.
Fast and efficient installation
The Dan-isoDUAL insulation half-shells provide a quick and efficient socket assembly. The flexible cellular rubber padding adapts easily to the joints and ensures a tight and precise insulation of the pipe systems. The product is designed to make installation faster and simpler, saving both time and money in the installation process.
Dimensions and fit
The Dan-isoDUAL bowls are supplied in dimensions from 125 mm to 630 mm and can be cut to desired lengths according to the customer's needs. The standard lengths of 380mm and 580mm enable most installation requirements to be met, and the flexible nature of Dan-isoFlex means that the product can be adapted to individual systems and installation requirements.
