The range of SFL linear blowers, which were introduced to the market in 2006, represent an important technical success for SIPA, with more than 200 systems installed in 47 different countries. These machines stand out on the market due to their high productivity (up to 1,800 bottles/hour/cavity) and low energy consumption, but above all as a result of their versatility and flexibility. |
By making simple modifications to the same machine it is possible to produce a large variety of bottles, including:
- Standard bottles
- Hot-fill bottles
- Large bottles (up to 16 litres)
- Fully-customised bottled for cosmetics, detergents and chemical products
- Bottles with handles formed in the body of the bottle
- Containers with shaped necks
- Oval bottles with differential heating
- OPP bottles
- PLA bottles
- Small bottles for pharmaceutical products
- Extremely light bottles with lightweight necks
The SFL blowmolders also benefit from all the other technological innovations of the rotary blowmolders (SFR) developed by SIPA, especially the patented oven system, and they guarantee the lowest energy consumption in their category.
The adoption of a fully electrical operational system, which is fast and precise, guarantees the maximum energy saving for the mechanical movements for the specific production output.
The oven for the thermal conditioning of the preforms ensures their perfect conditioning with lower temperatures and more efficient ventilation. This results in a significant energy saving and a considerable flexibility in the adjustment of the heating-stretching-blowing process.
In order to reduce the air consumption for blowing, SIPA uses the new and exclusive air recovery system, ARS Plus, on the SFL blowers. The exhaust air recovered with the ARS Plus version (recently tested) may be used not only for pre-blowing, but also for high-pressure blowing. With this option, the size of the air compressor may be reduced by 35%, with a consequent reduction in energy consumption and costs.
