Mini size plastic granulate dryer for small material quantities

Compact top-mounted plastic granulate dryer with 1 – 24 liters dryer volume

Mounting directly on the feeding zone of the processing machine

Thanks to their compact design, the plastic granulate dryer can be easily mounted on the feeding zone of the injection moulding machine. The dried material flows directly from the dryer in the plasticizing cylinder, without re-humidification or cooling. The JETBOXX® plastic pellet dryers are used in particular where small quantities of material with highest drying precision are required.

Drying containers / conveying technology

Drying containers

Glass- or stainless steel. Balanced distribution of the compressed air guarantees, that your material is dry and homogeneous at the right temperature.

Matching compressed air conveying devices for all JETBOXX® dryers

The control unit can be removed without tools

The control can be removed from the drying container easily by means of clamping locks. For the time of service like recalibration, a dryer control in replacement will be provided by HELIOS.

Double-walled special glass

The whole inner body of the drying container consists of one single piece of special glass and is shaped conically at the outlet. A cushion of air is created by assembling with the outer glass, that functions according to the principle of a thermos flask. This is how you save energy. Another advantage of the glass construction is the all side transparent visibility into the drying container. Contaminations are immediately apparent when changing the material.

Air input - distribution

Balanced distribution guarantees, that your material is dry and homogeneous at the right temperature. The conically shaped inner glass forces the inrushing dry air through the material output and ensures, that the granule already at the machine feeding zone is kept at the right temperature. A constant flow stabilizer made of stainless steel distributes the dry air flowing upwards across the entire cross section of the cylindrical container and avoids, that the material flows too quickly through the container center. For cleaning purposes the stabilizer can be removed manually without tools.

Split version

For particularly difficult space conditions the drying control and the drying container can be arranged separately as convenient. The dry air is led into the container by an insulated hose (max. 1m). The heating control regards occurring heat losses of the hose connection.
