BAND HEATERS WITH BLOWER ASSEMBLY
Ventilated band heaters are some heating units fitted with
forced air blowers. This system enables a faster cooling of the
scabbard.
Mostly used for extruders and press moulding machines, this
technology allows efficient working of the resin and of the
sensitive plastic materials, which need high and stable
working temperatures.
A ventilated band heaters assembly enables to prevent
barrels from the self-overheating effect.
The association between band heater and ventilation is a
good answer to these requests :
- quick heating process thanks to band heaters,
- quick cooling thanks to the ventilation system by forced
air heating, minimizing the thermal inertia of the scabbard.
CHARACTERISTICS
The frame made in polished or treated stainless steel
consists of 2 halfs cylinders connected by a hinge. This one
will channel the air on the scabbard in order to optimize the
cooling effect.
A security system maintains the frame on the scabbard to
enable intervention without the risk that it separates from
the scabbard .
Band heaters are set up on a frame gathering the
connections of band heaters.
(Number of band heaters depending on space).
An intensive cooling effect generated by the forced air
blowers and combined to a good thermal conductivity
thanks to the dielectric insulator of the band h. will allow
rapid elimination of calories.
Ceramic or mica band heaters, according to the application.
IP 40 band heater
The band heaters’ clamping is made barrel nuts. The frame is
closed by adjustable fasteners.
Connection : terminals under box, single or three phase
voltage. Tangential or radial position, centered on the height of
the ventilated assembly and fitted on the frame opening.
Products are made in accordance with the EN 60335-1 norm
Wattage tolerance : +5% -10%
Leakage current < 0.75 mA/kW.
OPTIONS
To define your product, refer to p 18.
In order to protect users from eventual burning, an antiburning
sheath (also called open work sheath) can be
installed in a band heater wih blower assembly.
Band heaters with blower assembly, can be fitted with
temperature regulating sensors. In this case a special boring
should be foreseen. See option 2, p12.
