SunSurfs Twin Way Pre Insulated Flexible Solar Hose
This hose is used to connect solar thermal collectors to solar storage water tanks.
Specifically designed for solar thermal panels:
1. Each coil includes both the feed and return pipes.
2. A flexible high-grade stainless steel tube 316L(or 304).Maximum pressure DN 16 /17.5 bar; DN 20/17.5 bar,DN25 17.5 bar Rated burst pressure 200 bar
3. 100% Genuine EPDM insulation pipe. light, flexible, closed cell, synthetic caoutchouc; free of PVC and non- CFC.Very good ozone resistance, UV-resistant. Work Temperature range from -200 degrees to 150 degrees, Max to 175 degrees
1.Jacketing coated on the insulation pipe is a super high density water proof polyolefin copolymer foil. Excellent performance of UV-resistance, water proof and bird peck-Protective.
2. Save money. Easy connect, no soldering required, Saves installation time, reduction costs.
3. Save space. Minimal space required for installation · SunSurfs-FLEX Solar Hose Flexible stainless steel tube with insulation, minimal pressure loss.
