Pex-Al-Pex

BM AIR specializes in installations of chilled water systems to large server complexes. BM AIR uses Cross-linked Polyethylene piping as a reliable choice for distribution of water and glycol based cooling fluids through the Cooling Distribution Unit (CDU). The Pex-Al-Pex material allows flexible installation techniques that minimize joint use and prevent vibration transmission, while providing good strength and durability for system pressures under 150
psig.

Pex-Al-Pex is a multi-layered composite tube consisting of an extruded inner core of PEX, a thin layer of aluminum, and an outer extruded covering of PEX. The PEX layers are bonded to the inner layer of aluminum using a melt
adhesive.

The aluminum layer between the PEX allows it to be bent into an arc, retain its shape, and prevents kinking. This unique property allows tight bends to be made without the use of fittings which reduces the overall joint count in a typical installation and is a major reason that BM AIR uses this type of material for its distributing of chilled water to its desired location.

The aluminum layer keeps the piping from returning to its original coiled shape, which makes installation easier and requires fewer fixtures to hold the Pex-Al-Pex in place.
