The tunnel is designed to sterilize and depyrogenise vials by a laminar flow of hot air with continuous process. Grade A is assured in all tunnel areas above the openings of the vials. Vials are transported through the preheating zone, heating zone and cooling zone by a conveyor belt made of stainless steel wire mesh.

Key Features

• Scientific calculation, modular design and Independent air duct design.
• Negative pressure sealing for the HEPA in the heating zone.
• Double cooling zone to prevent thermal shock.
• Flexible pressure zone concept for safe processes.
• Validation ports for filter integrity test, particle counting and air velocity.
• Power failure protection: backup power supply switch / compressed air cooling in the heating zone.
• Different working modes.
• Critical parameters of the process are continuously monitored and printed.
• Automatic gate between different zones(option)
• Automatic tight gate for cooling zone(option)
• Discharge device for the end process(option)
• Sterilize the cooling zone by heat(option)
