The S series represents SMIPACK's “historic product” and is aimed at a sector closer to industry, because it achieves fairly high speeds. The S series of L -chamber packaging machines includes four models for hourly production of up to 900 packages.    

• Sealing and heat shrinking system in a single operation
• Welding blade with PTFE cover
• Air cooling of the machine frame
• Closed circuit liquid cooling of sealing bars
• Coolant level indicator
• Quick adjustment of the height of the conditioning dish with an external crank
• Movable product holder plate, not linked to the film reel support to better adapt the film to the dimensions of the package to be wrapped
• Bell retainer electromagnet
• Emergency button
• Automatic reopening of the bell
• Automatic package exit using a motorized conveyor belt
• Flextron® control system with:
  1. Alfa-digital LCD control panel with a 16-bit microprocessor board and solid state relay, allowing simple and precise control of all common operations, such as:
     • machine condition
     • number of packages produced with electronic parts counter
     • soldering temperature adjustment
     • adjustment of the bell opening delay
     • adjustment of the retraction delay
     • adjustment of the retraction time
     • temperature control of the shrinkage chamber
     • packet exit speed
     • possibility of memorizing up to 10 different work cycles: consequently production increases and use is simplified
     • possible malfunction
  2. Modular power section, separated from the control panel and characterized by:
     • solid state relays, which last longer and simplify maintenance
     • in case of failure, it is possible to replace the only damaged module, without losing the data contained in the memory
• Reduced energy consumption
• Compliance with CE standards
