Valsir has commenced the fabrication and sale of a new product that has been designed especially for refrigerating systems: the new multi-layer Pexal pipe covered with a special insulating layer with a thickness of 10mm.

Such a thickness (greater than the usual 6mm) combined with the specific properties of the insulating material in PEHD with closed cells and with a conductance coefficient of =0.0397 W/mK, allow the:

Elimination of the formation of condensation, and therefore of the risk of damages to walls and ceilings.

A significant reduction of energy consumption, an important factor above all today when the cost of energy is on the increase.

The new multi-layer Pexal pipe for systems with refrigerated water is made up of:
