The Flexible Tube System

A flexible high-grade stainless steel helical or annular tube encapsulated in a weatherproof UV-stable and PVC-free insulation for both lines. This insulation provides excellent thermal stability. A silicone electrical cable for the temperature sensor is integrated with the insulation jacket. The complete tube system allows quick and easy installation.

ADVANTAGES HELICAL TUBE VERSUS ANNULAR TUBE IN SOLAR-SYSTEMS

- No air bubbles during system filling due to helical design

- 20 % more flow volume compared to annular type

- No deposits because of the helical design

- A unique conical sealing ensures high temperature stability and 100 % tightness

- The assembly is extremely easy and the joints can be made on the spot without any special tools

ADVANTAGES OF HELICAL TUBE VERSUS COPPER TUBE IN SOLAR-SYSTEMS

- Is manufactured from 316 stainless ensuring high pressure resistance and good heat transfer

- The assembly is extremely easy and the joints can be made on the spot without any special tools

- Significant reduction in costs due to reduced installation time – no soldering required

- A unique conical sealing ensures high temperature stability and 100 % tightness

- Small coils ensures low weight for transport
