High Pressure Compressor Plants to provide PET-Stretchblow Systems with oilfree blow air.

Under consideration of product-, project and environmental data GloCon sizes these "sub-plants" and generally supplies them as part of a systems package up to the bottling line … incl. the empty- bottle-air conveyor transport to the rinser/filler. |

B - Process support aggregates for injection moulding of preforms:

The resin drier dries the highly hygroscopic resin granules. The sufficiently dried material is an essential pre-requisite for a preform of impeccable quality with dimensional consistency which can be properly stretchblown. As a rule a drying time of 4-6 hours must precede the actual fluxing, plasticizing and injection of the material.
Even more than for blow moulding the sufficient cooling function is essential : one of the two cooling circuits provides the cooling for the drier, the hydraulic system of the machine and the cabinet - this would be a 20°C- circuit; the second circuit would provide the cooling effect for the mould, the takeout robot and - should the site of operation not be air conditioned - to the dehumidifying device. It is the mould which absorbs large volumes of clean 6°C-water for it to operate at short cycle times (= high productivity).
In order to prevent water from condensing in the cavities and on the cores resulting from the effect of the dry cold air it is imperative to either air condition the operating environment of the mould or to sue a dehumidifying cell instead.
For this purpose GloCon would install a dehumidifier unit. By way of a pipeline the humid air will be evacuated from the mould and preform takeout robot area.
Based on project and environmetal data GloCon sizes these machines and devices and usually supplies them as part of the systems package.
