25+25 heating + 25+20 sanitary QUAD
25+25 heating and 25+20 sanitary Microflex QUAD (160mm casing)
Flexible pre-insulated, self-compensating underground pipe.
Two heating pipes and two sanitarypipes hot water pipe and a pipe for the circulation loop. Designed for heating water (flow and return).
Corrosion-resistant transport pipe in cross-linked PE-Xa in accordance with EN ISO 15875, with yellow oxygen diffusion barrier in accordance with DIN 4726 for the heating water pipes.
Thermal, elastic, CFC-free foam insulation made from cross-linked PE-X with closed microcellular structure.
Minimal water absorption capacity of < 1% in accordance with ISO 2896.
Insulating PE centrepiece guarantees an effective separation of flow, return, hot water and circulation pipes.
Corrugated outside casing in HDPE, provides high-grade protection to the piping system.
The Hyper Flexibility of the Microflex Piping System
Placement of the pipe over obstacles and around corners is possible.
The inside bending radii of the different pipes are specified in the Product Table. Measurements are taken from the inside of the pipe. A re- serve factor is taken into account.
