Granulate dryers with dry air technology

Since HELIOS was founded by Klaus Wilhelm in 1982, our focus has been exclusively on material handling in the plastics industry.

Even if the focus was on planning and supply of central pellet drying systems and central material supply systems in the early years, we noticed the lack of a drying system for small throughputs of less than 10 kg/h per machine in the injection molding process. Especially for small throughputs and/or in case of frequent material changes, central drying and material supply systems are rather unsuitable, because the subjects overdrying, post humidification and dedusting appear to be impossible to control. The cleaning effort may be enormous.

Based on the removable HELIOMAT drying containers, the expansion of the system including a removable dryer control for different container sizes and throughputs was presented at the K-1998 - called JETBOXX^®. That system is suitable for batch drying as well as for continuous drying. Thanks to the HELIOS digital pneumatics used, just as much of compressed air as necessary is consumed for the fulfillment of the drying task. JETBOXX^® with digital pneumatics was patented in Europe and US and since then more than 10.000 were sold.

From 1999 Start and market launch of the WINstandard series.

On the occasion of the K-2001 fair a JETBOXX^® with a comfort and user benefit - once thought impossible - was presented for the first time.

This JETBOXX^® of the series –Economy– included already as standard a finely graded dry air flow rate control, a database for plastic specialized and throughput dependent dryer adjustments, a display for drying parameters, temperature, dry air volume flow, dew point of the dry air as well as energy consumption at a current throughput. Furthermore, a control for a compressed air conveyor with mixing function for 2 components and automatic filter cleaning.

This innovation of HELIOS can be described – not entirely without pride – as „mother of all current small batch compressed air dryers“. Imitated many times, but still unequalled!

K-2004 Introduction of the WINsystem^® series as a follow-up to the -Economy- series.

Since K-2007, all JETBOXX^® dryers have optionally a material feed with or without dedusting.

2012 the parallel introduction of the price-performance optimised JETBOXX^® WINneo version took place.

2020 ‒ 2023 a complete new development of the hard- and firmware for WINneo^® 2 series with the experience of 20 years of the JETBOXX^® system.
