Chilled Water Systems

Afripex pure Pex-a piping for chilled water systems

The preferred chilled water pipe for large contractors, because it is:

  • the fastest and easiest pipe system to work with
  • with the lowest total cost to install
  • the world’s safest connection technology, and
  • design life that will outlive the equipment.

Other benefits of Afripex pure Pex-a pipe:

  • Reliability of installation: The elastic properties of the pure Pex-a pipe are used to make the connection. The installer only “stretches the elastic”. The system shrinks by itself to make a perfect connection, every time
  • No theft value: A full plastic pipe system, including threaded connectors leaving nothing to steal
  • The system is self compensating, even when pre-insulated. This means not having to worry about other services in your way, saving labour and parts in constructing expansion loops.
  • Even in its naked form, the Afripex pure Pex-a is more thermally insulative than most alternative systems. This reflects in clients saving money on energy.
  • Pure Pex-a is unique in that kinks can be repaired by use of a hot air gun, without damaging the integrity of the pipe. This allows for long runs to be installed without joins. It also facilitates easy installation and repairs in otherwise unreachable places.

Benefits of using Afripex pre insulated pipe systems

  • Our pre insulated pipe is significantly more insulative than building standard requirements. This additional insulation saves money spent on cooling, which would otherwise be lost in transit. This saving reduces operational costs and generates a healthy return on investment.
  • An added benefit is that the energy efficiency allows temperature generation units to be consolidated into single bigger units, with piped temperature distribution. These cost less to install and run, with less maintenance.
  • The insulation is jacketed, making the solution UV stable and fully weatherproof, allowing design flexibility.

Examples of application of Afripex pre-insulated pipe

  • chilled water can be piped on the top of a building, exposed to the elements without degredation, and without losing temperature. This allows reducing the number of chiller plants
  • a single chiller can service multiple buildings, with the building being connected by long lengths of pipe running underground.

Energy can be reclaimed anywhere and taken to where it is needed.
