Twin Way Pre Insulated Solar Hose

The Demax Twin Way Pre Insulated Solar Hose is a pre-assembled piping solution for solar systems, consisting of two SUS304 stainless steel tubes (feed/return), high-temperature EPDM insulation, a UV-resistant protective jacket, and an integrated temperature sensor cable. It enables non-welded, fast connections between solar components: the insulation preserves thermal efficiency (operating -200°C to 175°C), while the jacket shields against environmental damage. The twin pipes can split at a designated point for flexible installation, streamlining system setup.

Product Introduction

Main features

Features	Advantages
1. Twin-tube design (feed/return pipes) with marked lines + integrated silicone temperature sensor cable	1. Easy to distinguish pipe functions; eliminates separate sensor wiring
2. Core tubes: Flexible SUS304 stainless steel (max pressure 17.5 bar; burst pressure 200 bar; 1050°C heat resistance)	2. Durable, high-pressure/temperature tolerance; suitable for extreme operating conditions
3. Insulation: 100% EPDM (closed-cell; -200°C to 175°C; PVC/CFC-free; ozone/UV-resistant)	3. Excellent thermal retention; eco-friendly; long-term performance in outdoor/underground environments
4. Seamless UV-resistant jacket (polyethylene copolymer foil; 500h UV test passed)	4. Protects against UV, mechanical damage, bird pecking, and water intrusion
5. Pre-assembled, non-welded connection	5. Reduces installation time; lowers labor costs
6. Splittable twin pipes (break point for separate single pipes)	6. Adapts to varied installation spaces; no jacket damage during splitting
7. Coil lengths: 10/15/20/30/60m (custom lengths available)	7. Flexible sizing for different project scales; minimizes material waste
8. Lightweight, space-saving design	8. Easy to handle, even in confined spaces
