Product Description
Z. 122 nozzle band heaters are the confirmation in
this field of our step forward to the future.
In fact, the technical features of these new heaters
are better than the ones commonly used. Built with
a rectangular tube (mm 8.6 x 4.6), they give an
excellent guarantee of mechanical resistance
against impacts and knocks as well as safety when
using tools during maintenance operations.
Z. 122 nozzle band heaters are totally protected
from the plastic corrosive action and are
hermetically sealed from liquid plastic.
Their rectangular shape with a 8.6 mm long side,
acting as heat dissipator, allows us to reach the
highest thermal exchange with the nozzle.
