Ensure highly consistent bottle quality for your hot-fillable and pasteurisable PET bottles by making use of the processing capabilities of the Sidel Matrix eHR blower range with electrical mould heating.
When hot-filling sensitive beverages like juices, nectars, soft drinks, isotonics and teas (JNSDIT), in order for them to be filled safely, the bottles are heated to a temperature between 80° and 95°C.
To withstand those temperatures, PET bottles are produced via a heat-resistant, stretch blow moulding process, commonly referred to as HR (heat resistance) or heat set.
The process is based on higher preform reheating capability and blowing bottles in hot moulds, usually at temperatures above 120°C.
The revolutionary Sidel eHR blowing solution replaces heating of the mould for the bottle body, traditionally carried out with oil. Instead, heating is via electrical resistance creating a temperature increase that is three times faster.
This process achieves numerous operational benefits in terms of bottle quality, performance, process flexibility, uptime, energy savings and operator safety.

The eHR blower shares a number of commonalities with the standard configuration of Sidel Matrix blowing architecture. For example, mechanical settings are the same and 73% of the eHR blowing station components are similar to those of standard Sidel Matrix blowers. But furthermore it benefits from all the most recent and proven Sidel technologies used for regular production of PET bottles including:
Sidel's eHR blowing process is very responsive. Mechanical output reaches up to 2,000 bottles per hour per mould. Temperature variation and discrepancies between different blowing stations are kept to an absolute minimum.
Sidel Matrix eHR blower offers great savings in terms of electricity and air consumption, through its innovative electrical mould heating and the proven Sidel Matrix blower technologies.
By eliminating hot oil altogether, the design of the Sidel Matrix eHR blower prevents hazards caused by the leaking of oil, such as operators' slipping and the contamination of filled bottles.
The new blowing process using heating by electrical resistance is used in the Sidel Matrix Combi Hot Fill, complementing the advantages of the standard Combi configuration that integrates the blowing, filling and capping functions in a single enclosure.
