Summary
A flexible and efficient pipe system for heat pumps, local heating networks and house-to-house connections.
A flexible and efficient pipe system for heat pumps, local heating networks and house-to-house connections.
Application
Heat pumps (air/ water heat pumps in particular) and local heating networks.
Heat pumps (air/ water heat pumps in particular) and local heating networks.
Description
The FLEXSTAR low-temperature system is a pre-insulated, flexible, and robust pipe system. FLEXSTAR is suited for connections to heat pumps, integration into local heating networks and for house-to-house energy distribution.
FLEXSTAR UNO (single medium pipe) and FLEXSTAR DUO (twin medium pipes) in custom cut to length or standard coil lengths or as ready-to-install heat pump sets, including accessories.
Features and benefits:
- Operating temperature: maximum 95°C (fluctuating).
- Operating pressure: 6 bar.
- Dimensions: FLEXSTAR UNO from DN 20–50, FLEXSTAR DUO from DN 20–40.
- Carrier pipe: PEXa.
- Insulation: polyurethane (PUR) foam.
- Outer jacket: linear low-density polyethylene (LLD-PE).
- Manufactured in accordance with EN 15632-2.
