Oil-free Reciprocating Compressors for PET Bottle blowing

PET compressors enter a new era

SIAD Macchine Impianti has been present in the food and drink sector for many years and is fully aware of the standards created to prevent food contamination with oil and toxic elements. For this reason it has designed and developed compressors for blowing PET bottles with standard features capable of supplying oil-free high pressure air.

All this thanks to continuous research, constant machinery upgrading and significant investments in both staff and technology.

SIAD Macchine Impianti supplies oil-free, piston compressors with water-cooled cylinders for blowing PET bottles that are ready for use: they are complete with electrical motors, heat exchangers, instrumentation, various accessories, electrical panel and mounted on skids.

PET bottle blowing compressor models

To meet varied demands, we have designed two lines: a three-stage line , now joined by the recently launched VITO range, and the Screw + Booster piston compressor line – the BS line:

• Compressor for blowing PET bottles: the VITO line

This is the latest range of PET compressors, the result of a precise design and development initiative lasting over16 months, with numerous prototypes constructed and many months of testing. The VITO range was created to meet the demands of those who want first of all energy efficiency, lower environmental impact, maximum reliability and a design that meets the requirements of maintenance and operational ergonomics.

• Compressors for blowing PET bottles: the TEMPO line

This involves a full range of compressors that supply high-pressure, dry, totally oil-free air. It is an extremely efficient range, with low power consumption and high productivity fitted with stainless steel piping and large and efficient exchangers.

• Compressor for blowing PET bottles: the BS line

The BS line is the result of the combination of two complementary compressors: a screw compressor and a piston one, both oil-free and forming a single package to offer a totally oil-free air quality.

Our compressors compress air and respect all the regulations in force in the food sector.

• Pulsation, acoustical, torsional,bending analysis.
• Finite elements structural verification.
• Fluid-dynamic verification
• Fatigue calculation
• Measurement and verification of vibration, ultrasonic, thermography, radiography
• Chemical, physical and metal particles oil analysis.

Software for Mechanical calculation
3D modelling, static elastic Fem analysis, infinite life fatigue analysis
Elastic bodies motion of the complete frame, static elasto-plastic Fem analysis
Multiaxial fatigue analysis with the algorithm of Dang Van or Brown – Miller – Morrow

Computational Fluid Dynamics (CFD) Software
The gas paths are studied by the computer with most advanced CFD software with the aim to reach at the same time a small clearance volume, for a greater volumetric efficiency, and large and well profiled passages for low pressure losses.

SIAD Macchine Impianti has been involved in the food & Beverage sector for many years and is aware of all the regulations aimed at keeping foods uncontaminated from oil or toxic agents. It has developed a compressor with standard characteristics to supply oil-free, high pressure air for blowing bottles in PET. All of this is thanks to continual research, to constant updating of the machines and to major investments in staff and technology.
