Use appropriate formers and bend springs. References BI, BA, BM and BM-F

Both grades comply with operational conditions 10 bar at 70 °C however the standard pipe has a thicker aluminium core and even higher performance in fail safe conditions.

A PE-RT or PE-Xc pipe expands more because it is a solid plastic pipe. A RIXc or standard pipe has an aluminium core and therefore expands less.

There is physical and chemical cross-linking. Tubes are cross-linked to optimise the strength and durability of the tube.

Chemical cross-linking is achieved by adding peroxide or silane to polyethylene. A physical cross-linking is created by exposing the tube to electron beams. Henco uses physical cross-linking because it is the purest cross-linking.

The test plugs may be only used for up to 3 months under a maximum constant pressure of 10 bar. The plugs are not suitable for making permanent sealings and are purely for testing the system. They are not reusable

Yes, for example as ground pipes. In this case, we recommend combining the Henco standard multilayer pipe with the PVDF press fittings. It is best to protect the pipe additionally with, for example, a PVC protective tube. Please note that Henco inspection certificates only apply to indoor installations.

The insulation is vapour-proof, but not suitable for long-term outdoor use or applications in moist sandy soil. If the insulation must nevertheless be used in those conditions, it is best to apply a waterproof protective tube (such as a PVC pipe) around the insulation.

Yes, the pipes may be exposed to sunlight for a short period of time. Polyethylene is not UV-resistant, so Henco tubes should not be permanently exposed. For specific outdoor applications, Henco can produce unique UV-resistant pipes on request.

The minimum temperature for Henco multilayer pipes and PVDF press fittings is -20°C. For solid plastic pipes, the minimum temperature is 7°C.

It can if the paint is water based.

Henco tubes up to and including 26 mm diameter can be bent with the appropriate tools from the Henco product range. For pipes with a diameter from 32mm onwards, it is best to use couplings.

The number of motors per zone depends on the thermostat connected to the zone.

• Analogue = without screen
• Digital = with display
• Analogue 24V = 5 motors
• Analogue 230V = 10 motors
• Digital 24 V = 5 motors
• Digital 230V = 5 motors

The control has a number of connection terminals to which motors can be connected:

• Wired 6-zone = 15 connecting terminals
• Wired 10-zone = 21 connecting terminals (maximum 18 connected)

Note: Each individual terminal can be connected to multiple motors if a relay is used.

You can connect as many zones (motors) to one thermostat as you want. The only limitation is the number of connection terminals on the control to which motors can be connected:

• Wireless 1-zone = 1 connecting terminal
• Wireless 8-zone = 12 connection terminals
• Radio 12-zone = 18 connecting terminals

Note: Each individual terminal can be connected to multiple motors if a relay is used.

When using a wet system without insulation, the lowest possible build-up is: PRO + 30mm anhydride screed

Can Henco tubes be rinsed with hydrogen peroxide/sodium hypochlorite/chlorine dioxide?

When rinsing pipes, it is best to consult the table below. In case of additional questions, please contact your Henco representative.
