ENERGY SAVING BAND HEATERS
The energy saving BAJ band heaters are specially set up on
injection moulding machines and extrusion heads. By
combining a band heater to a BAJ insulation system, we can
guarantee a very low heating loss, both conductive and
radiative. This system allows a lower energy consumption
than compared to an installation equipped with standard,
non insulated band heaters.
This system exists in 2 types :
- mini B.A.J. : insulation provided by a thin layer of insulator,
energy saving of 15% on average.
- B.A.J. : insulation provided by a thick layer of insulator,
energy saving of 40% on average.
The energy saving band heater technology also called BAJ
(Brevet Acim Jouanin), can be adapted to all kind of band
heaters, mica and ceramic.
The particular design allows a very good preservation of the
insulator even with high temperature.
The advantage of the BAJ is the thermal isolation of each
bandheater, which enables to respect the different heating
zones on injection and extrusion lines.
CHARACTERISTICS
External sheath, in polished steel or steel treated in the
surface, protecting the insulator from all sort of compression.
It acts like a reflector, spreading the radiation towards the
surface to be heated. The outside frame is made of two halfs
cylinder connected by a hinge for easy mounting on the
sheath.
Insulating structure with a low thermal conductivity, placed
between the frame and the band heater. The thickness of the
the insulator has been specially improved in order to
minimize eventual loss.
Mica or ceramic band heaters, depending on the
application.
Their thermal capacity respects all insulation factors in order
to avoid overheating problems and premature failure of the
band heater. IP 40 band heater.
The band heater and the frame are clamped with barrel nuts,
which allows a strong clamping and is specially designed
for a mounting where space is limited.
Connection under cap : axial, radial or tangential, set up on
the outside frame. Different types of connection, see p 11.
Products are in accordance with the EN 60335-1norm

- BAJ assembly on a mica or ceramic band heater.
In order to protect users from eventual burning, an antiburning
sheath (also called open work sheath) can be
installed on a band heater supplied with the BAJ system.
The energy saving band heaters can be fitted with sensors
supports. See option 2, p12.
