2 1 Description and key features 1.1 Description The ST is a hot water shrink tunnel designed for use with the full range of Cryovac shrink bags. It has a wide range of application and is used as the final component of many Cryovac packaging systems. The machine consists of a conveyor which transports the packages through a hot water spray enclosed in a tunnel. Water temperature is regulated by an electronic control unit to ensure that a consistent shrink and pack appearance is obtained. All functions are automatic and the machine does not require operator intervention except for switching on and off. Two versions of the machine are available; with heating by means of electric immersion elements or by a closed loop steam coil. Extensive use of insulation is used to minimise the external surface temperature and prevent excessive heat loss. Construction is simple and robust. All critical parts are treated against the corrosive environment often found in food production and packaging rooms. Designed with ergonomics safety and hygiene in mind it is easy to use and clean, simple to maintain and meets all relevant European legislation for safety and hygiene. 1.2 Key features No operators required Continuous process Electronic temperature control for consistent and repeatable results Low temperature control - prevents use of machine until water is at the correct operating temperature Vertical water vapour duct - makes installation easier Alarm lamp to indicate failure of conveyor motor or fan motor - gives early warning of breakdown Fully automatic control of water level Valves to adjust water flow through spray bars Variable speed conveyor in option Produced in 2 versions, electrical and steam heating Good thermal insulation, for example 4 curtains for insulation of the hot water spraying area Small floor space requirement PakFormance Compliance Kit as an option upon Customization Request, enabling access to the Sealed Air PakFormance functionalities through networking of the machine Hygienic design makes cleaning easy and effective Good access for maintenance, for example a removable water tank Robust, high quality build standard using food approved materials throughout 2
