Leister LE 5000 HT-U / LE 5000 HT-S, 3 x 200V/7.0kW, 3 x 400V/7.5kW
Details Hot air side sealing for liquid packaging
The hot air sealing unit for liquid packaging include two different units: The LE 5000 HT-U air heater has the hot air outlet on the upper side, while the LE 5000 HT-S blows the hot air downwards. The air outlet openings are designed precisely for welding the longitudinal seam in liquid packaging. Thanks to the great thermal insulation on the units, the maximum amount of energy is implemented in the weld seam.
The sealing unit reaches production speeds up to 700 m/min and operates with an air temperature of 900 °C/1652 °F. The temperatures and the air flow can be easily controlled with the sealing units. This makes the hot air process much more precise and climate-friendly than the process with gas flame. The pre sealing units consist of two LE 5000 HT-U devices, which are used in the prefold section of the machine shown by Fortuna Spezialmaschinen GmbH.
