JETBOXX® top-mounted mini dryers

Mounting directly on the feed section of the processing machine

Thanks to their compact design, the plastic granulate dryers can be easily mounted on the feed section of the injection moulding machine. The dried material flows directly from the dryer in the plasticating cylinder, without humidification or cooling. The JETBOXX® top-mounted dryers are used in particular where small quantities of material with highest drying precision are required. Based on the small dimensions the JETBOXX® mini dryers can be mounted on the injection molding machine directly.

Drying containers

glass or stainless steel


The detachable drying control JETBOXX® can be adapted to a glass- or stainless steel drying container.

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

Uniform 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 that is already located at machine feed is kept at the right temperature. A flow stabiliser 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 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.

Variable filling height

Overdrying protection
The maximum filling height in case of automatic filling can be reduced by the conveyor in container sizes 6 / 12 and 18 liters by the adjustable filling level sensor. Therefore the optimal container volume for keeping the permitted residence time can be adjusted.

Conveyors - Filling options

Manual filling

The drying containers can be opened easily on top for filling or cleaning. Glass containers have a swivelling cover, 6/12/18 liter containers have a hinged cover.

Compressed air conveyors

  • 1 component conveyor
  • 2 component conveyor
  • with or without dedusting

Calibration service

HELIOS dryers are maintenance-free except filters.
All the resin dryers are tested for several hours before delivery.

Dryer calibration in standard
All HELIOS dryers are factory calibrated for two dew point values, two drying temperatures and three volume flow rates with a calibration certificate.

Repeat calibrations
are possible locally by a HELIOS service technician or with HELIOS inplant. For this purpose, the dryer control is simply detachable by means of quick clamps, no tools are necessary. To avoid production stops during the service, there are interim devices available with HELIOS.

Long-term warranty for all* dryers regarding

  • Maintenance
  • Repeat calibration
  • Availability of interim devices
*for all JETBOXX® dryers built since 1998

After Sales Service

You are not alone with the HELIOS components, we will support you with whole the process up to the start-up and training of your staff. This is what the partnership exactly involves.
