Sidel Matrix eHR blower

Top HR bottle quality with electrical heating of moulds

Sidel Matrix™ eHR blower for JNSDIT:






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.


Specific PET bottles to resist hot-filling temperatures

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.


Staying ahead with innovative electrical mould heating

Matrix blower cutoutThe 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.



  • Benefits of Sidel Matrix eHR blower

  • Based on proven Sidel Matrix blower technologies  

    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. It also benefits from all the most recent and proven Sidel technologies used for regular production of PET bottles including:


    • electrical stretchingProven Sidel Matrix Ecoven: allows a wider process window with a great heating capability and reduced installed power. Improved ventilation with optimal air flow contributes to better heating regulation and temperature gradient within the preform walls.
    • Electrical stretching: as it is contactless and does not wear, it is very robust. It delivers high bottle quality and contributes to increased output. It offers more process flexibility and ensures continuity and reliability. It can be combined with the Sidel Matrix Intelliblower™, which brings control and self-regulation to the blow moulding process. Electrical stretching also contributes to increasing output.
    • AirEco2 air recovery: reduces energy consumption through the two air-recirculation steps. Available as an option, air recovery drastically decreases the need for high pressure air.
    • New automation architecture: based on four distributed processors (preform feeder, oven, blow wheel, Human Machine Interface). It allows for faster automation, giving a more reactive and qualitative blowing process.

  • Enhancing consistent performance  

    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.


    • eHR mouldWith a temperature increase three times faster, it accurately provides the correct temperatures from the very first bottles produced. 
    • The set-point temperature is easily reached because probes are directly located inside each mould shell in order to regulate the temperature as close as possible to the bottle as it is formed.
    • All the bottles undergo the same thermal conditioning and offer a consistent performance when placed on the supermarket shelf.
    • The latest generation of blowing valve on the Sidel Matrix blower, combined with the mechanical blow nozzle system, electrical stretching and automation, give great control of the blowing curve. This allows for an increased mechanical output by up to 2,000 bottles per hour per mould, while maintaining enough cycle time to ensure a consistent blowing process.

  • Great energy savings  

    EcovenSidel 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.


    • Electrical mould heating avoids temperature variation and heat loss.
    • Save up to 45% in electricity consumption with the Sidel Matrix eHR blower compared with the previous generation of Sidel blowers that used traditional mould heating with oil.
    • A further saving of 25% in electricity consumption can be achieved with the performance of the Sidel Matrix Ecoven using infra-red lamps with ceramic technology instead of metal reflectors.
    • A reduction by up to 45% of air consumption is possible for a production output of 1,800 bottles per hour per mould by implementing the AirEco2 option. 


  • Hygiene and safety  

    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. 


    • mould supportWith electrical stretching, there is no need for lubrication above the neck of the bottle, removing the risk of contamination. 
    • Some components are lubricated for life, with specific treatments to eliminate the need for greasing operations, simplifying maintenance. 
    • Food-grade grease is used for parts that do need lubrication. 
    • The proven Ecoven ventilation with air filtration ensures a more hygienic production.
    • The moulds are insulated from the mould supports. The hot temperature is focused on the moulds avoiding any thermal constraints on other nearby machine components. This contributes to safer intervention conditions for the operator.

  • Benefitting to the Sidel Matrix Combi Hot Fill  

    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.


    • Eliminates the conveying, handling, accumulation and storage of empty bottles. 
    • Compact and ergonomic, it optimises line layout with a smaller footprint.
    • Controlled production environment ensures hygiene and food safety is kept under full control.
    • Electronic filling valves are equipped with individual flow meters for highly accurate volume dispensing with minimal product wastage.
    • Hygienic design and contactless filling valves ensure complete product safety.
    • Can be used to bottle a broad range of products with and without pulps or particles and can accommodate neck changeovers easily.
    • The product circuit is equipped only with sanitary valves, which makes cleaning easier for complete food safety.
    • The fluid speed in the filling valves is monitored during cleaning to be greater than 1.5 metres per second, while temperature is kept under control in each filling valve due to the recirculation flow monitoring.
